Breaking down where time is being spent in my design (time in seconds). @User had some ideas on how to speed up DRC, but I haven't had a chance to try them yet.

4058.0 magic DRC
2412.0 magic spice
 433.0 TritonRoute
 369.0 magic mag_gds
 355.0 magic gds_pointers
 300.0 magic lef
 292.0 netgen
 183.0 yosys synth
 183.0 yosys synth

Could you share what those ideas are?

A few things. He suggested running

DRC(routing)

which avoids any GDS based rules. Might be good enough for design exploration before doing the final tape out. Tim also has some ideas on how we could parallelise DRC, which would be very nice.
