Not able to use peek, poke, step and expect for testing a simple hardware description

[Pinaki Chakrabarti]

Hello,

Recently I downloaded Chisel-3 from Github . I saw the examples and ran with the provided Makefile. It is able to create a .v file along with .fir, .cpp and a .json file. But when I tried experimenting with my own hardware description and tried using peek, poke, step and expect, as suggested in many chisel related documents/tutorials, I could not use those. It was saying undefined or not available. I also wrote a tester class extending from PeekPokeTester but did not help.

What is needed to do so that I can see all the generated files for my test case ?

Also, is there any way I can see the .fir (IR) dumping in different phases ?

Please help.

Thanks,

Hi Pinaki,

I would recommend you start with the chisel template which can be found here: https://github.com/freechipsproject/chisel-template

This already includes an example of how to write a test: https://github.com/freechipsproject/chisel-template/blob/main/src/test/scala/gcd/GCDSpec.scala

You can launch the test either with `sbt test` or when you use an IDE like IntelliJ it will show a green arrow next to the test that you can click to launch it.

Hope this helps.
