APB3 to AXI4 Lite Converter Testbench

You can choose to generate the testbench when generating the core in the IP Manager Configuration window. To generate testbench, the Testbench Deliverables Option signals must be enabled.

Note: You must include all .v files generated in the /Testbench directory in your simulation.

Important: tested the testbench generated with the default parameter options only.

provides a simulation script for you to run the testbench quickly using the Modelsim software. To run the Modelsim testbench script, run vsim -do modelsim.do in a terminal application. You must have Modelsim installed on your computer to use this script.

The testbench includes several tests that use either randomly generated data or user input data. The testbench also includes a comparator to indicate a pass/fail for the read and write operations.

Table 1. Test Types and Input Type
Test	Description	Input Type
Write	Single write test	Random or user input
Read	Single read test	Random or user input
Continuous Write	8 (default) cycles write test	Random
Continuous Read	8 (default) cycles read test	Random
Write Wait	Single wait write test	User input
Read Wait	Single wait read test	User input
Write then Read	Single write then read test	User input
Error	Error test	User input

After running the write simulation, the test prints the following message:

80000- PASS! the output write address is correct
80000- PASS! the output write data is correct

After running the read simulation, the test prints the following message:

480000- PASS! the output read address is correct
510000- PASS! the output read data is correct

After running the error simulation, the test prints the following message:

5980000- PASS! the signal is correct on State Error
