EMIR analysis is one of the more challenging fields of circuit simulation. It requires the power and/or signal net parasitics to be preserved for the later IR drop and EM current analysis. At the same time the EMIR analysis requires SPICE accuracy for properly checking the EM currents against the current limits defined by the foundry. The Cadence transistor level EMIR analysis tool is Voltus-Fi XL which uses the Spectre EMIR solution for simulating the circuit behavior and for calculating the IR drop and EM current data. This blog explores the value of Spectre X in EMIR analysis and compares it against Spectre APS for both, direct and iterated EMIR method.(read more)![]()
