[Feature request] Add a command to report the utilization info. #351

Open zapta opened 4 months ago

zapta commented 4 months ago

This request is for a command similar to apio time that reports the FPGA utilization. Alternatively, the time and the utilization reporting can be combined into a single reporting command, that can be extended later to report additional information.

By utilization I mean something similar to this part of the the apio build -v log:

IceStudio shows this information in the status bar, scraped from this log test. I wonder if the nextpnr team would agree to add a --report flag that emits the report as flag text or structured json.
