ppl interactive tweaking #1997

Closed oharboe closed 1 month ago

oharboe commented 1 month ago

These changes support updating and seeing the results interactively in the GUI of changes to io pin placement.

Example:

  1. make floorplan
  2. make gui_2_1_floorplan.odb
  3. Now run source scripts/io_placement_util.tcl
  4. Resize GUI so that pins are rendered(this is probably a tiny bug in the GUI...)
  5. Tweak pin configuration .tcl files or e.g. set ::env(PLACE_PINS_ARGS) {-annealing -min_distance 7 -min_distance_in_tracks}
  6. Run clear_io_pin_constraints; source scripts/io_placement_util.tcl

See results immediately.
