[BUG] cva6/core/Flist.cva6 mentions " ENV variable CVA6_REPO_DIR" but there are others

[rajatkmitra]

Is there an existing CVA6 bug for this?

• I have searched the existing bug issues

Bug Description

The header should also mention that HPDCACHE_DIR and HPDCACHE_TARGET_CFG need to be set. I noticed that HPCACHE_DIR can easily be inferred as it already resides under -
cva6/core/cache_subsystem/hpdcache/
So why do we need a seperate macro for it ? Also where do I find the options for HPDCACHE_TARGET_CFG?

Hi @rajatkmitra, thanks for your interest in OpenHW and CVA6. We are updating our script-ware and associated documentation to simplify supporting CVA6 and also to enable compilation of multiple configurations of the CVA6. We will ensure your questions are addressed in a future update of the docs.

Many thanks @MikeOpenHWGroup !!

Hello @rajatkmitra
You do not need to setup these variables when using cva6.py, which is the recommended way to simulate, except for the pk, which is under fixing. Do you get the issue using pk?

[rajatkmitra]

Hi @JeanRochCoulon
As you noted in the othere post #1358 , I had some difficulties using pk.. The instructions were not clear. But @valentinThomazic
clarified the directions. I noticed that the default Makefile is looking for verilator target in cva6/tmp. Again this was missing from the instructions. I have still to try using pk and will inform shortly if that was successful. My goal is to replace verilator with Xcelium and then use pk + Xcelium. If that is successful I plan to run ariane SoC on emulator - Z2.

Hello @rajatkmitra
@valentinThomazic has just updated the README.md. Pk support has been removed but recommandations to simulate CVA6 updated. Can you review it to give us your feedback ?
