Sigrity is a suite of advanced analysis tools used for power integrity (PI), signal integrity (SI), and electromagnetic interference (EMI) in electronic systems. It is part of Cadence’s electronic design automation (EDA) ecosystem and is widely used for analyzing and validating high-speed PCB and package designs. Sigrity helps engineers understand electrical behavior at both board and system levels before physical implementation.
Sigrity Aurora
