2.8.2.1. Generating the LL 100GbE Testbench
A single procedure generates the testbench and example project (for Stratix V variations) or the testbench, compilation-only design example, and hardware design example (for Arria 10 variations). The procedure varies depending on your target device. To generate these demonstration aids:
- Follow the steps in Specifying the IP Core Parameters and Options to parameterize your IP core.
- If your IP core variation targets a Stratix V device, go to step 4.
- If your IP core variation targets an Arria 10 device, in the LL 100GbE parameter editor:
- On the Example Design tab, select Simulation, Synthesis, or both to specify whether you want to generate the simulation-only testbench, the compilation-only and hardware design examples, or all three options.
- Click the Generate Example Design button to generate these options for the IP core variation you intend to generate.
Tip: You are prompted to locate the new testbench and example project in the directory <working directory>/alt_eth_ultra_100_0_example_design. You can accept the default path or modify the path to the new testbench and example project. - Generate the IP core by clicking Generate HDL for Arria 10 variations or Generate for Stratix V variations.
Note: If your IP core variation targets a Stratix V device, when prompted at the start of generation, you must turn on Generate example design. Turning on Generate example design is the only process that generates a functional testbench and a functional example project for Stratix V variations.
When the IP core is generated in <working directory>, the testbench and example projects are generated in different locations depending on the device family your IP core variation targets.
- For Stratix V variations, the testbench and example project are generated in <working directory>/<IP core variation>_example_design/alt_eth_ultra.
- For Arria 10 variations, the testench and the compilation-only and hardware design examples are generated in the directory you specify in Step 3. If you do not modify the location text at the prompt, they are generated in <working directory>/alt_eth_ultra_100_0_example_design.
The directory with the testbench and design example has four subdirectories for Arria 10 variations and three subdirectories for Stratix V variations:
- example_testbench
- compilation_test_design
- hardware_test_design
- ex_100g or ex_100g_caui4 , for Arria 10 variations only
The ex_100g or ex_100g_caui4 directory contains a copy of the IP core variation. The testbench and design examples (compilation-only and hardware design example) for your Arria 10 IP core variation connect to the copy in this directory rather than to the copy you generate in <working directory>.
