genus reports referenced package cv32e40p_fpu_pkg does not exist

[Ceridli]

Component:RTL: For issues in the RTL (e.g. for files in the rtl directory)

Component:Tool-and-build: For issues in the tool and build flow (e.g. Makefile, FuseSoc, etc.)

Steps to Reproduce

Please provide

1. git hash : I don't know what this is, but I used version 1.3.0
2. Command line: I used 'bender script genus > bender-genus.tcl' at the top of source directory to generate synthesis scripts.
3. Logfile and/or wave-dump info (screen shots can be useful)

Hi @Ceridli,

Bender.yml and src_files.yml files are not used in OpenHW group methodology, only cv32e40p_manifest.flist. Those yaml files came from ETHZ repo and I am not sure they have been used/updated for v1.0.0 RTL freeze. What can be seen is that v1.0.0 version of cv32e40p_decoder.sv was already using that fpu package but Bender file was not listing it.

For sure between v1.0.0 and v1.3.0 I have not updated them, only updated cv32e40p_manifest.flist and added another one including FPU called cv32e40p_fpu_manifest.flist So Bender file including FPU does not exist even if I see dependencies to fpnew git repos (now managed with local copies using vendorization flow).

You can submit a PR to dev only touching those files to fulfil your needs, we will merge it in dev and master after review.

Cheers, Pascal.

Thanks for the response. I was not familiar with 'bender' methodology. I liked the idea though. It could be especially useful if you are doing transaction level verification. Different tools may require different directives, and they need to be passed to them accordingly. For example, your docs recommends some changes for clock gating. I did the change for v1.0.0 but forgot about it in v1.3.0. My synthesis should have failed. I will strip the file list to manifest versions, and try again.

@Ceridli , feel free to send a PR with the fixes for Bender if you wish, happy to merge them
