Generate Vivado hardware usage reports #6

Closed lindemer closed 3 years ago

lindemer commented 3 years ago

I'd like to view the hardware use statistics after building this repository for an Artix-7 35T FPGA (e.g., https://github.com/SpinalHDL/VexRiscv/pull/148#issuecomment-722227413), but the report files don't appear to be generated automatically. Is there some way I can enable this? @kgugala maybe you know something about this? Thanks in advance.

Those are generated by default, you can find all the reports in build/arty/gateware directory. In e.g arty_utilization_hierarchical_place.rpt I got:
