Hi, After some CV32E40P RTL analysis, here is the status: - FS (and SD) are always hardwired to 0 even when FPU = 1 After some RISC-V spec analysis, here...

Hi, Compared to the single-core test-bench parameter values, I just changed: - EnableNaNBox to 1 even if I guess it is not necessary. But it allows to have all FPnew...

Due to following Hardware Loop constraint from User Manual, both counters can never be decremented at the same time. So hwlp_dec_cnt_i can not be at 2'b11 but only 2'b01 or...

Hi, Starting from the proposal made by @jm4rtin and amended by @jeremybennett in [pulp_encoding_blocks-jpb.xlsx](https://github.com/openhwgroup/cv32e40p/files/5109998/pulp_encoding_blocks-jpb.xlsx), here is a new PULP re-encoding proposal for CV32E40Pv2 [pulp_encoding_blocks-OPHW-jm-jpb-pgo.xlsx](https://github.com/openhwgroup/cv32e40p/files/8132021/pulp_encoding_blocks-OPHW-jm-jpb-pgo.xlsx). It contains few corrections and modifications...

Hi, Here is a new version [pulp_encoding_blocks-OPHW-jm-jpb-pgo-2022-04-06.xlsx](https://github.com/openhwgroup/cv32e40p/files/8429042/pulp_encoding_blocks-OPHW-jm-jpb-pgo-2022-04-06.xlsx) with X's removal and some bit manip instructions grouping in custom-3.

Thanks John. #700 will only be documentation updates. I will submit another PR with RTL changes.

Final version of the document with removal of old JM encoding proposals [pulp_encoding_blocks-OPHW-final-2022-06-22.xlsx](https://github.com/openhwgroup/cv32e40p/files/8967606/pulp_encoding_blocks-OPHW-final-2022-06-22.xlsx)

Hi As always when starting to implement specification and verifying it, you find some problems you didn't anticipate. Here things are that some ALU control signals are not generated in...
