Thanks for this @ludovicpion. I would like to request a few changes:

1. There are separate copies of the LICENSE file for the pulse_gen and bp_gen components. These are not necessary since there is a top-level LICENSE file for this repository and there are license headers for all svh files.
2. The bp_gen has an added layer of heirarchy (bp_gen/bp_gen) that does not seem to have any purpose.

Hi @MikeOpenHWGroup,

Regarding layer of heirarchy for the bp_gen, it is a mistake. I just fixed it.

For the LICENSE, all the cv_dv_utils have the same of managing it. I know that there is some redudancy but we agreed at the begining that it was ok to keep it like this. Is there any problem now?

Thanks,
Ludovic

Thanks for fixing the "extra layer of hierarchy" issue. The redundant license files are unnecessary, but I am unaware of any legal reason not to included them, so I will approve/merge this PR.

Thanks for the contribution to CORE-V-VERIF!
