The simulation design example top-level test file is basic_avl_tb_top.sv. This file instantiates and connects an ATX PLL. It includes a task to send and receive 10 packets. The simulation design example for 40GBASE-KR4 variations also exercises auto-negotiation and link training, if enabled.

File Names

Description

Testbench and Simulation Files
basic_avl_tb_top.sv Top-level testbench file. The testbench instantiates the DUT and runs Verilog HDL tasks to generate and accept packets. The testbench also implements auto-negotiation and link training if enabled in a 40GBASE-KR4/CR4 DUT.
Testbench Scripts
run_vsim.do

The Mentor Graphics* ModelSim* SE or Questa* Intel® FPGA Edition script to run the testbench.

run_vcs.sh

The Synopsys* VCS* script to run the testbench.

run_vcsmx.sh

The Synopsys* VCS* MX script (combined Verilog HDL and System Verilog with VHDL) to run the testbench.

run_ncsim.sh

The Cadence NCSim script to run the testbench.

run_xcelium.sh The Cadence Xcelium* script to run the testbench.
