[Question] How to use testbenches?

[thomas-woehrle]

Hi,

I want to use Teros' Testbench capability. The documentation thinly shows how to create testbench templates, but I didn't find more in the documentation about Testbenches and neither in the GitHub issues - feel free to refer me if there is existing documentation.

I am interested how I can use the Testbenches feature and what it is capable of doing. Can I aggregate different testbenches here and execute them centrally?

Screenshot from VScode currently:

Thanks in advance and as for the last issue I created (#698) : If I end up knowing well how the feature works after I have worked with it for a while, I will gladly contribute to the documentation.

You can follow this tutorial: https://terostechnology.github.io/terosHDLdoc/docs/tutorials/tutorial_vhdl All the help in the documentation improvement is appreciated.

And: https://terostechnology.github.io/terosHDLdoc/docs/project_configuration/

I have worked through all those documentation pages before, they are not of great help to me unfortunately :/. Mainly because of the issue that I don't even know what sources and libraries can be used for (see this issue #698).

[thomas-woehrle]

You can follow this tutorial: https://terostechnology.github.io/terosHDLdoc/docs/tutorials/tutorial_vhdl

Sorry, but unfortunately this doesn't help either, because it not thorough enough imo.

This is its explanation of running a simulation:

And for me that leaves a lot of things open, fe how to even get a test which can be run in the first place...

I greatly appreciate your work with the extension, but I find it tough to use

[qarlosalberto]

But I don't understand your question. Do you want to run a simulation? Or are you learning HDL?

[thomas-woehrle]

I want to run a simulation and I am wondering how TerosHDL is intended to help with that.

Lets say I have a testfile TestBench.v and I am manually running it like so:

iverilog -o test_executable TestBench.v
vvp test_executable

Is Teros gonna help automize that or can it instead be used f.e. for triggering cocotb tests or ... ?

I don't know what I can use it for and how I can set up tests with it.

[qarlosalberto]

Then you have to follow this tutorial: https://terostechnology.github.io/terosHDLdoc/docs/tutorials/tutorial_vhdl

You only need to use Icarus instead GHDL. Let me know if you are stucks in any step.

[thomas-woehrle]

Okay, I followed the tutorial.

I set my TestBench file (FloatAdditionTB.v) as top module file and ran the TestBench from the Teros UI.

I get this error:

I have Icarus set up as a tool in Teros

[qarlosalberto]

It seems that you have GHDL. Your linter is Icarus, but your simulation tool is GHDL.

[qarlosalberto]

Go to config, tools and select Icarus

[thomas-woehrle]

Sorry, I am not sure what you mean.

Do you mean this:

I can't select it as simulation tool here

[qarlosalberto]

Click in "Tools". There is another tab.

Okay, now it works.

Additional question though:

What do these settings do:

Switching between execution mode "Command Line" and "GUI" didn't change anything. And the TestBench should create a .vcd ($dumpfile("FloatAdditionTB.vcd");), but gtkwave is not run atm. Not sure if this would be intended
