When I use Edit--> Split Plane--> Create On some designs, the copper pour doesn't adhere to the design constraints. For example, the shape to pin distance might be set at 6 mils but I will get a drc violation because the copper pour is actually 5.999 mils away from the pin. I have an easy work around for that one but sometimes it violates the route keep-in. Any suggestions? John
Take a look at Sourcelink solution # 11149292. Basically, they recommend adding a small oversize value to the global shape parameter clearance table.
Thanks Randy R. I appricate the quick response too. John
Really the subject should be "Rounding Error: Shape parameter settings VIA Thermal/Anti vs DRC" If the DRC value is equal to the Anti-Pad value a rounding error occurs. This is a bug and I submitted PCR# 759117 a while ago to address the issue. Oddly enough it was partially fixed in 15.5 but still errors exist (even in 15.5.1-43P). I'm waiting for a response from R&D. The original thought was it was fixed but that does not appear to be the case.
