Viso Parasitic Analyzer and Debugger Viso analyzes the electrical properties of RC parasitic networks which crucially impact circuit behavior in nanometer processes. These impacts affect circuit gain, delay, maximum clock rate, cross-coupling, level of ESD protection and other features, which can cripple a design. Viso’s parasitics-focused approach enables quick analysis of interconnect in order to pinpoint problems. It provides timing estimation and accurate comparison of different extracted netlists.
