roms missing when building caravel user project

[mattvenn]

Hi Eric, not sure how to solve this in context of your project, but wanted to make a note. The paddle and sine roms needed to be in the src directory for yosys to find them in the caravel context.

so what's interesting is that in this case the roms need to be in the same directory as the source files. but they need to be elsewhere for the tests. What would be ideal is if we could just have them in the src location and somehow make the tests find them.

I guess we could just put symlinks in the src directory as well, but it's weird that in the caravel context they need to be src not your top level.

Yeah, the tools seem fairly picky in resolving rom paths. It would make sense for them to at least look in the same directory as the source file that loads them, followed by the tool's own PWD, but unfortunately they don't all do that. iverilator does not look relative to the source file and so fails when run from somewhere else.

As mentioned I've been creating symlinks in various places, but it's obviously not ideal :-)

I'm assuming you ran into this running make user_project_wrapper in caravel_user_project?

How did you work around that? It's unclear from what directory yosys is run and therefore where to create more symlinks.

[mattvenn]

I symlinked them from the wrapped_pong/pong/src directory. Might have got that directory wrong, but the same directory as paddle.v that tries to read the rom. That's what I meant about it being weird that when we run yosys in this context it expects the roms to be where the source files are. I still don't know how to alter this.
