5. Board Update Portal This chapter describes the Board Update Portal which allows you to upload new designs and provides access to useful and relevant information about the kit. Board Update Portal This development kit is shipped with an example design stored in the factory portion of the flash memory on the board. Whenever jumper J62 is set to LOAD FACTORY, the Stratix IV GX FPGA is automatically configured with the Board Update Portal example design. The example design is an embedded web server, which serves the Board Update Portal web page. The web page allows you to upload new FPGA designs to the designated flash memory on your board, and also provides links to useful information, on the Altera website at www.altera.com, including links to kit-specific and design resources. After the Board Update Portal is used to successfully update a design, jumper J62 can be set to LOAD and the design configures upon reset or power up. To do so, set the configuration program select jumper, PGMSEL, (J62) to the position (jump pins 1-2) and power cycle the board. This cycle can be repeated for different designs as long as the factory Board Update Portal is preserved. If the Board Update Portal is corrupted or deleted from the flash memory, refer to “Restoring the Factory Design to the Flash Device” on pageA–4 to restore the board to factory condition. The source for the Board Update Portal design resides in the <install dir\kits\stratixIVGX_4sgx230_si\examples. It consists of a Nios II embedded processor, an Ethernet MAC, and an HTML web server. When the board is connected to the network, the Nios II processor obtains an IP address and allows the browser access to its HTML web page. This section provides instructions on how to connect to the Board Update Portal web page. 1 Before you proceed, ensure that you have the following: ■ A PC with a connection to a working Ethernet port on a DHCP enabled network. ■ A separate working Ethernet port connected to the same network for the board. ■ The Ethernet and power cables that are included in the kit. Connecting to the Board Update Portal Web Page 1. With the board powered down, make sure jumper J62 is in the LOAD FACTORY position (pins 2-3). 2. Attach the Ethernet cable from the board to the LAN. 3. Power up the board. The board connects to the LAN’s gateway router, and obtains an IP address. The LCD on the board displays the IP address.

(J19 and J20) Note to Table6–1: (1) The clock input is expected from the socketed oscillator (Y3) (soc_clk) on the board. If you are targeting –2 speed grade device on the board, you can use 425 MHz. For –3 speed grade, the maximum data rate limit supported is 6.5 Gbps. Therefore, you must use 312.5 MHz (312.5*20 < 6.5 Gbps) and not the 425-MHz clock crystal. Configuring the FPGA Using Quartus II Programmer It is sometimes necessary to use the Quartus II Programmer to configure the FPGA with specific .sof files, such as the designs in Table6–1. Before configuring the FPGA, ensure that the Quartus II Programmer and the USB-Blaster driver are installed on the host computer and the development board is powered up. To configure the StratixIV GX FPGA, perform the following steps: 1. Start the QuartusII Programmer. 2. Click Add File and select the path to the desired .sof. 3. Turn on the Program/Configure option for the added file. 4. Click Start to download the selected file to the FPGA. The FPGA is configured when the progress bar reaches 100%.

6–2 Chapter 6: Stratix IV GX Transceiver Signal Integrity Demonstration LCD Information 1 To determine if the appropriate test design .sof is programmed, check the LCD for the test design number. Refer to “LCD Information” for more information. LCD Information The LCD shows the following information: ■ The Stratix IV GX device junction temperature in Celsius. ■ The power in watts for the different transceivers (VCCA_L/R, VCCT, VCCR, VCCH_GXB, VCCL_GXB) and core (VCC) voltage supply rails. Turn the rotary switch SW16 to observe the different voltage supply values. To learn more about the switch position for displaying the various supply rail values on the LCD, click the Help button in the demonstration application. ■ The sof/pof number that is programmed is indicated by ‘pof’ followed by the number. The power values shown for the VCCA_L/R and the VCCH_GXB assume that the jumper settings are set to 3.0V and 2.5V, respectively. Click the Help button to see the required jumper settings. Running the Demonstration Application and Test Designs The demonstration application communicates with the set of test designs provided with the kit. You can change the various transceiver parameters that are described in this section. To run the application, make sure that the board is powered up properly and there is a USB cable attached, then go to the <installdir>\kits\stratixIVGX_4sgx230_si\demos\ directory and double-click on stratixIVGX_si_demo.exe file. Ensure that the StratixIV FPGA is programmed with the .sof specified in Table6–1 on page6–1. 1 Certain DLLs are required for the demonstration application (stratixIVGX_si_demo.exe) to function properly that are not included with the kit installation software. These needed DLLs are installed with the Quartus II Subscription Edition software, version 9.1. Once installed, you can immediately uninstall the Quartus II software afterwards if you don’t want to purchase a license. Refer to “Installing the Quartus II Software” on page3–2. To enable the application to communicate with the board, click the Connect button. To close the application, click the Disconnect button (Figure6–1). 1 Because the demonstration application communicates with the board using the same interface as the Quartus II Programmer or SignalTap®II Embedded Logic Analyzer, you can run only one of these applications at a time. 1 The application will not run unless the USB cable is attached, power is applied, and the correct .sof is programmed to the Stratix IV GX FPGA as specified in Table6–1 on page6–1.

Gain DC gain. preemphasis/deemphasis. PE pre, 1stpost, and 2ndpost settings represent different taps. Resets The following list describes the available resets: Table6–2. Reset Description System Reset for the transceiver. Error Reset for all the error counters to zero. 1 After the System Reset is asserted, the DataChk Status may show unsynced for some channels due to the asynchronous nature of the reset. Asserting the Data Patrst synchronizes the error checker to the transmitted data. Help The Help button displays the image of the Stratix IV signal integrity board and also highlights the channel locations and their data rates based on the .sof loaded. Power Down Turn on Powerdown to power down the transceiver block. Serial Loopback Serial loopback is available for all the channels and can be controlled during run time. After the serial loopback status in the interface changes, the DataChk Status field may show unsynced for some channels due to the asynchronous nature of the serial loopback signal. The Data Patrst should be asserted in this case to synchronize the error checker with the transmitted data. Transceiver Signal Integrity Development Kit, December 2011 Altera Corporation Stratix IV GX Edition User Guide

Chapter 6: Stratix IV GX Transceiver Signal Integrity Demonstration 6–5 Running the Demonstration Application and Test Designs In the signal_integrity_demo1.sof, internal serial loopback is not enabled for the two channels configured in PCI Express (PIPE) mode. Therefore, you must connect an external SMA cable between the transmit output and the receive input to loopback the data. Autolink Setup This feature provides the following options: Table6–3. Parameter Description You can manually change the preemphasis and equalization to observe the Manual setting that provides an error free link. For more information about DataChkStatus, refer to “Link Statistics Tab” on page6–6. When you select this option and the start button, the hardware finds a PEandEQ preemphasis and equalization setting that meets the bit-error rate (BER) of 10–12. When you select this option and the start button, the hardware finds an EQonly equalization setting that meets the BER of 10–12. When you select this option and the start button, the hardware finds the PEonly preemphasis settings (pre tap and 1stpost tap) to obtain an error free link. 1 The receiver data checker must be active to determine whether the settings attempted by the hardware are successful. Therefore, you must connect the transmitter output to the receiver input through external cable. If you are evaluating the characteristic of a third party upstream transmitter connected to the Stratix IV GX receiver, you must supply the appropriate data pattern as selected in the application, for the data checker to determine the BER for a given setting. Autolink Start and Stop Selecting the start option enables the hardware to perform the operation specified in Autolink setup. After this setup is complete, the stop field gets highlighted in green or red. Set the stop field and record the converged settings. The following explains the color coding of the stop field: Table6–4. Color Code Description green the hardware successfully finds the settings that give an error free link. if the hardware is not able to find the settings, it provides the setting that red yielded the least number of errors. yellow the hardware is finding the PMA settings. The DataChk Status field also shows whether the hardware is in progress, done (successful), or no setting (failure) status.

6–6 Chapter 6: Stratix IV GX Transceiver Signal Integrity Demonstration Running the Demonstration Application and Test Designs Data Patterns The application supports PRBS15i, PRBS7, PRBS23, CJTPAT, compliance pattern (only for specific designs and channels), high frequency, and low frequency patterns. No synchronization patterns are sent prior to sending the PRBS pattern. Therefore, you can use a third party receiver to recognize the PRBS/CJTPAT data. Data verifiers are not available for the high frequency (1010..) and low frequency (5’1s and 5’0s) patterns. Link Statistics Tab The Link Statistics settings include the following options: Table6–5. Parameter Description Displays the BER, number of bits received, number of errors received, and the error slope based on the What statistic to selection from the list. display? The error slope shows the error trend (increase or decrease). You can use this statistic to determine whether the PMA control settings must be increased or decreased to get an error free link. Inject Error Injects errors in the channels. Every time this button is asserted, one-bit error is introduced. Data Patrst Reset for the data pattern generators and checkers. Based on the test design selected, the application displays the serial data rate of the transceiver Data Rate channels. GXB Encoding Displays whether the data sent by the test design is 8B/10B encoded. The DataChk Status field displays the following: ■ synced status displayed in green indicates that the error checker has received the predefined header byte and no errors are detected. ■ unsynced status displayed in gray indicates that the error checker has not received the selected pattern. DataChk Status n If the DataChk Status field shows unsynced, check whether the transmitter of the channel showing unsynced is connected to the receiver channel by external cable or by internal serial loopback. However, when sending the high frequency data pattern, the DataChk Status shows unsynced. This is because the error checker is not provided for high frequency pattern. ■ error status indicates that the error checker is detecting errors in the received pattern. Shows whether the transceiver Clock Recovery Unit (CRU) is locked to the reference clock or to the CDRLock Mode data. When the transceiver locks to the incoming data, this field displays data indicating that the receive PLL has recovered the clock from the incoming data. When you click the Freeze display button, the display field does not change and the counting Freeze Display continues. When you click the Unfreeze display, the current running values are shown.

Channel Reconfig Tab This tab is only available when signal_integrity_demo3.sof is loaded. You can dynamically select the input reference clock from the socket clock input or an external SMA clock input (J19 and J20). To receive the input clock from the external SMA, turn on switch to SMA clock. The serial data rate of each transceiver channel can be 16 times or 20 times the clock rate. The Change Data Rate controls configure each transceiver block with one of the following data rates: 5Gbps— Configures the transceiver channel to run at 16 times the input reference clock. If input reference clock is 312.5MHz, the transceiver runs at 5Gbps. 6.25Gbps— Configures the transceiver channel to run at 20 times the input reference clock. If input reference clock is 312.5MHz, the transceiver runs at 6.25Gbps. Reverse serial 5G (Post CDR)— Configures the transceiver channel in reverse serial loop back mode. In this configuration, the output of the RX CDR that is configured to track serial data input at 16 times the input reference clock is looped to the transmitter serializer. The serializer is clocked by the recovered clock generated by the RX CDR. Data checkers are not available for this option. Reverse serial 6.25G (Post CDR)— Configures the transceiver channel in reverse serial loop back mode. In this configuration, the output of the RX CDR that is configured to track serial data input at 20 times the input reference clock is looped to the transmitter serializer. The serializer is clocked by the recovered clock generated by the RX CDR. Data checkers are not available for this option.

6–8 Chapter 6: Stratix IV GX Transceiver Signal Integrity Demonstration Running the Demonstration Application and Test Designs Reverse serial (Pre CDR)— Configures the transceiver channel in reverse serial (Pre CDR) mode. The received serial data input is looped to the transmit buffer before it passes through the RX CDR. Data checkers are not available for this option. EyeQ Tab This tab is only available when signal_integrity_demo3.sof is loaded. The options set the phase step to move the sampling point of the recovered data. For more information about this feature, refer to “EyeQ” in the StratixIV Dynamic Reconfiguration chapter in volume2 of the StratixIV Device Handbook. The following EyeQ features can be used in channels configured up to 6Gbps: Manual— Sets the phase step from 0 to 31. Once the GUI and the hardware computes 3*10E12 bits, the GUI displays the bit error rate (BER) for the phase step, plots the value, and records the BER information for each phase step in a .csv format. The block<block number>stats.csv file is saved in the same folder from which the application is launched. Automatic— Automatically sequences through the phase steps 0-31, plots the value, and records the BER information for each phase step in a .csv format. 1 For proper GUI operation, close all the .csv files previously created by the GUI before launching the GUI. To estimate the eye opening, use the following equation: Eye opening (as a % of unit interval) = N*1/32*100 +/- 3%, where N is the number of phase steps with no errors.

A. Programming the Flash Device There is a common flash interface (CFI) type flash memory device on the StratixIVGX transceiver signal integrity board. When you first receive the kit, the CFIflash device arrives programmed with a default factory FPGA configuration for running the Board Update Portal example design and a default user configuration for running the primary transceiver signal integrity demonstration. There are several other factory software files written to the CFI flash device to support the running of the Board Update Portal. These software files were created using the Nios II EDS just as the hardware design was created using the Quartus II Design application. f For more information about Altera development tools, refer to www.altera.com/products/software/sfw-index.jsp. Board Update Portal CFI Flash Memory Map TableA–1 shows the default memory contents of the 512-Mb (64-MB) single-die CFI flash device. For the Board Update Portal to run correctly and update designs in the user memory, this memory map must not be altered. TableA–1.

A–2 Appendix A: Programming the Flash Device Parallel Flash Loader Parallel Flash Loader The development kit features a MAX II configuration design in the <install dir>\kits\stratixIVGX_4sgx230_si\examples\maxII_epm1270_si directory that includes a PFL megafunction. The Parallel Flash Loader (PFL) on the MAX II device is used to configure from CFIflash when the RESET SW8 is pressed or the board is powered up. f For more information about the PFL megafunction, refer to AN 386: Using the Parallel Flash Loader with the Quartus II Software. Custom User Design As you develop your own project using the Altera tools, you may wish to program the flash device so that, upon power up, it loads the FPGA with your own user design. With the Nios II EDS tool sof2flash, your Quartus II compiled .sof can be converted to a .flash file. The .flash file can then be written to the user hardware location of the flash memory using either the Board Update Portal or the Nios II EDS nios2-flash-programmer from a Nios II command-line shell. If you used the Nios II EDS to derive your software design, you can use the Nios II EDS tools to convert your compiled and linked software Executable and Linkable Format File (.elf) design to .flash files. After your design files are in the .flash format, then both hardware and software files can be written using the Board Update Portal or using the Nios II EDS nios2-flash-programmer. 1 For more information about Nios II EDS software tools and practices, refer to www.altera.com/products/ip/processors/nios2/tools/ni2-development_tools.html The following sections describe how to program the flash device using first the Board Update Portal, then using only the Nios II EDS command-line tools. Creating Flash Files Using the Nios II EDS If you have hardware developed using the Quartus II application, and software developed using the NiosII EDS, follow these instructions: 1. On the Windows Start Menu, go to All Programs> altera> Nios II EDS> Nios II Command Shell. 2. In the Nios II Command Shell, navigate to the directory where your design files are located and type the following Nios II EDS commands: ■ For .sof Quartus II hardware files: sof2flash --input=yourfile_hw.sof --output=yourfile_hw.flash --offset=0xC20000 r ■ For .elf Nios II software files: elf2flash --base=0x08000000 --end=0x0BFFFFFF --reset=0x08820000 --input=yourfile_sw.elf -–output=yourfile_sw.flash --boot=$SOPC_KIT_NIOS2/components/altera_nios2/boot_loader_cfi.srec r Transceiver Signal Integrity Development Kit, December 2011 Altera Corporation Stratix IV GX Edition User Guide

Appendix A: Programming the Flash Device A–3 Nios II EDS Flash Programming Instructions 1 For boards with dual-die CFI flash devices, use --base=0x0A000000 and --offset=0x00020000. For more information, refer to the Board Revision History appendix of the Transceiver Signal Integrity Development Kit, Stratix IV GX Edition Reference Manual. These steps result in a set of .flash files suitable for Board Update Portal writing to the user flash memory. For more information, refer to “Board Update Portal” on page5–1. 1 If your own design uses additional software files such as files used by the runtime program or image data, you must first convert the files to .flash format and concatenate them into one your_sw.flash file before using the Board Update Portal to upload them. 1 The Board Update Portal standard .flash format conventionally uses either <filename>_hw.flash for hardware design files or <filename>_sw.flash for software design files. If you have a hardware .sof developed using the Quartus II application that operates without a software design file, you should still use the Nios II EDS tool sof2flash to convert the .sof to .flash file, as described earlier for the hardware files. When the Board Update Portal is implemented in this case, only the yourfile_hw.flash file is selected without the yourfile_sw.flash file. You can program the .flash files using the Nios II EDS nios2-flash-programmer instead of the Board Update Portal as described in the next section. Nios II EDS Flash Programming Instructions To program the .flash files or any compatible S-Record File (.srec) to the board using nios2-flash-programmer, perform the following steps: Firstly, configure the FPGA with a compatible .sof for flash-programming: 1. Move jumper J62 from LOAD FACTORY to LOAD USER (jump pins 1-2). 2. With the board powered up and the USB cable attached, as described in “Configuring the FPGA Using Quartus II Programmer” on page6–1, start the Quartus II Programmer. 3. Click Add File and select the following path: <install dir>\kits\stratixIVGX_4sgx230_si\factory_recovery\s4gx230_si_bup.sof 4. Turn on the Program/Configure option for the added file. 5. Click Start to download the selected configuration file to FPGA. The FPGA is configured when the progress bar reaches 100%, after which the user LEDs flash repeatedly on and off indicating that the flash device is ready for programming. Secondly, run the Nios II EDS nios2-flash-programmer: 1. On the Windows Start Menu, go to All Programs> altera> Nios II EDS> Nios II Command Shell.
