#250 Missing Cont in IO cells Issue created by dnltz I have a design with IO ring and DRCs report

LU.d

and

LU.d1

violations. Both rules are defined as following: image As you can see in the next image, all violations are located in the IO cells itself. It looks like there is quite some

Cont

missing. (Image is showing the

LU.d

violations). image We taped-out these cells in May and used Cadence for Metal fill. We also had no

LU.d

violations in that tape-out. So, seems like Cadence is smart enough to fill the missing

Cont

filler. However, I would propose to add the missing

Cont

to the IO cells directly. It's probably easier to just add it once instead of filling it in each design. --- The following image is showing the

LU.d1
