hello all,
i am using technology TSMC 65nm and i reach to final stages, now i am trying to add metal fill to avoid min density violations.
i am using ICV (ic validator) to do this on ICC2 using command (signoff_create_metal_fill).
here is a problem, when i run this command it takes time to finish and when finishing i don't see anything changes (no metal fill added in design).
i opened icv.log file related to metal fill, i see that it adds a metal fillers but i don't see anything.
i decide to run drc check using icv, still i have the same min density violations.
i decide to write gds and see layout in Klayout tool, nothing added in gds.
finally, i run icv standalone, it generates gds by new filling and when i merge it with original gds, the violations disapperes.
can anyone help me, i want to add fillers in design in icc2 and debug errors in gui of icv in design in ICC2.
thanks alot.
