getting the same - it looks like its inside the cells?
are you also getting "Poly resistor spacing to poly" ? @tgingold
t
No, but I also get 
poly overlap of poly contact < 0.08um in one direction (licon.8a)
.
t
@tgingold: Which cell(s)?
t
At least in clkdlybuf4s15_1 I also get 
Poly resistor spacing to diffusion < 0.48um (poly.9
when tapvpwrvgnd_1 is just on the left side of a conb_1
t
I believe that I may be using the wrong type of poly resistor in that rule, which means any such rule is a false positive. I'm going to look into it now.
@tgingold: The error in clkdlybuf4s15_1 is an actual error in the standard cell library, as far as I can tell.
t
Ok, I won't use that cell. Weird!
Thanks!
t
@tgingold: I just posted a corrected version of the GDS for that cell in github skywater-pdks issue #261.
t
Great!
