Hi.
I am suffering from a lot of DRC errors of Metal1 in P&R of ICC.
Calibre reports a lot of DRC errors while ICC doesn't report any error.
Total number of DRCs = 0
The main errors in Calibre are for Metal 1.
These are adjacent edges, spacing, minarea, spacing of VIA1.
I checked the tf file. The definitions for these parameters are correct.
What is the problem? Can anybody give me some suggestions?
After I execute route_zrt_detail, the number of spacing errors is decreased, but the number of Minarea error increases. In the std cell, there is no gds. Some errors can be fixed if the connect to the Metal 1 of std cell. But now, I cannot see anything of std cell. It is also difficult when I use Virtuoso to correct these errors because it may cause a short problem.
Any comments? Please.
