place_and_route: Syntax of generated textproto files #295

Closed mczyz-antmicro closed 8 months ago

mczyz-antmicro commented 8 months ago

Textproto files are generated from generate_power_results and generate_area_results, which are used in the global_routing.tcl. What syntax are they meant to be? By file extension, I presume that they are meant to be protobuf files, but unfortunately they are not consistent with protobuf syntax (you can test with protolinter). I propose to make effort to make these files consistent.

Example of generated file:

total_package_power_watts: 0.0059173996560275555
corner: "asap7-sc7p5t_rev28_rvt-ccs_ss_SS"
power_maginitude: "p"

They are text protos. https://protobuf.dev/reference/protobuf/textformat-spec/

Exactly what I was looking for is at the bottom of the page you linked, thanks!
