Hi, I am trying to find a loop in a particular net. I am able to get the routing either from net tracer utility or through power plot using DIVA. Now, I have a cell where I only have that particular routing. I wanted to find if there is any loop exists. If yes, I wanted the list of shapes and vias associated with that loop. There cloud be multiple loops. Loops can be filtered out based on the loop length. Any suggestion will be highly appreciated. Note : I am able to figure out loops in single layer using DIVA (geomHoles). Need to trace the loop with multiple layers through vias. Thanks, Amit
