Sigrity PowerSI

Sigrity PowerSI offers a quick and exact 3D full wave analysis of circuit boards and PC packages. With the results of this analysis problems in the domains of power integrity (PI), signal integrity (SI) and electromagnetic compatibility (EMC) can be controled. In the analyses numerous interpretations of electromagnetic couplings of wires and vias are available. An interpretation of the fluctuations of supply systems (power and ground) depending on e.g. simultaneous switching of the signals is an important point to guarantee the stability and the function of a circuit. Zones can be recognized in which the power supply is under or oversupplied.

With PowerSI frequency depending network parameter models can be extracted which enables to visualize understandingly complex coherences.
