laurentc2 / asap7_for_klayout Goto Github PK

Hey Laurent, Thanks a lot for the KLayout drc files. I assume these were for ASAP7 version 1.7 PDK.

I am currently using it for GDSII generated according to the rules here

I get over 350 issues when I run it for the GCD design. Is the .lydrc file applicable to the files described in the config.mk, or it needs to be modified?

If yes, could you provide the new DRC files, as this would be helpful for the current designs being implemented using OpenROAD Flow Scripts?

Looking forward to your reply and help!

A number of standard cells in https://github.com/The-OpenROAD-Project/asap7/blob/master/asap7sc7p5t_28/GDS/asap7sc7p5t_28_R_220121a.gds are failing the GCUT.GATE.EX.1 rule. It looks like the rule is checking both horizontal and vertical extension, but the rule definition is Minimum horizontal extension of GCUT past GATE

A number of the enclosing() checks are of the form .polygons.without_area(0).edges.with_angle(90):

gcut.enclosing(gate.and(gcut), 17.nm, projection).polygons.without_area(0).edges.with_angle(90).output("GCUT.GATE.EX.1", "GCUT.GATE.EX.1 : Min. horizontal extension of GCUT past GATE : 17nm")

This is producing many false positives. enclosing() can be filtered directly with angle(), and this seems to produce the correct output:

gcut.enclosing(gate.and(gcut), 17.nm, projection).with_angle(90).output("GCUT.GATE.EX.1", "GCUT.GATE.EX.1 : Min. horizontal extension of GCUT past GATE : 17nm")
