Causality Enforcement in Transient Co-Simulation of Signal and Power Delivery Networks

This paper discusses a transient simulation method that co-simulates the signal and power delivery networks in a packaged system. The method includes a novel delay extraction technique that enables the enforcement of causality conditions on the resulting transient waveforms. This paper describes the application of the method on a number of test cases to account for electromagnetic parasitics and cross-talk, and shows the scalability of the method for performing large sized transient simulations
