Hi guys
I'm using TSMC90nm and calibre.
When I draw a path with 45-degree, i get grid error in calibre DRC.
The error is on picture that attach to this message.
If i use 45-degree path, i get this error. Also the snap spacing has true value.
How can i resolve it???
This is a normal problem encountered when using paths at a non-orthogonal angle. I believe Calibre converts paths to polygons thus creating an off grid geometry. It does this because DRC has to check the actual spacing between geometry edges and not the path centerline. You will need to convert any non-orthogonal paths into polygons to solve this issue.
