Stimuli-Driven Power Grid Analysis

The terms vector and vectorless modes are commonly used in the context of dynamic power grid (PG) analysis, but what do these terms mean? The PG dynamic simulator uses a design’s activity suite to compute the voltages and currents in the PG network. In vector mode, logic simulation is used to generate the complete activity suite. Vector mode is typically referred as a VCD (Value Change Dump).... » read more
