wafer.space Community - Openroad GUI timing corner selection

I've tried googling this, but not having much luck yet. When opening the openroad-gui via librelane 'nom_tt_25C_5v00' timing corners are loaded and reported. I'm seeing a large gap between the slowest:'max_ss_125C_4v50' and fastest: 'min_ff_n40C_5v50' corners. Curious how I would load the other timing corners to visually see the paths, and maybe optimise macro placements. I've tried read_spef --corner <file>, but the corner names don't seem to be correct.

Quick and dirty: add e.g. DEFAULT_CORNER: nom_ss_125C_4v50 to your config and LibeLane will load this corner instead.

However, LibreLane should really load all timing corners that are available.
