IRIS – Fast RFIC Passive Extraction

Background

Xpeedic IRIS provides high frequency silicon design engineer a 3D fast EM simulation tool integrated in Cadence Virtuoso design flow to analyze on-chip passive devices. IC designers now have an automated way to access EM analysis of passive devices without limiting them to any specific PDK. IRIS is now an indispensable tool for the modern designer.
