Static IRdrop Analysis Using Open Source CAD Software

This paper investigates the open source static IRdrop analysis tool, PDNSim, which is part of the OpenROAD computer-aided design tool. The main approach used for static IRdrop analysis is discussed, namely the compilation of an equivalent circuit model used for further calculations. The results of static IRdrop analysis obtained using PDNSim are compared with the results obtained using modern commercial CAD tool and the error of the obtained analysis results is evaluated.
