A computer software implemented method of automatically determining adequacy of an integrated circuit electrical power distribution and signal protection schemes, based on netlist data, which does not rely on other a-priori data. The method determines which nets are power supply nets, their connectivity to different types of power supplies. The method automatically traverses the nested block structure of the circuit, ascending and descending in block hierarchy as needed, and automatically determines (often based on an inspection of the power needs of the individual block devices) the type of power supply needed to power that block, power supply adequacy, and adequate protection of signal interfaces to other blocks. The method can present the analysis in a high level report, such as a graphical map, that can make root cause sources of power and power related signal interface problems immediately evident, and which suppresses most irrelevant details.
