How stable is your IC Package's PDN?

There are three goals for a power a delivery network (PDN): sufficiency, efficiency, and stability.  Simultaneous switching of Gigahertz speed signals (i.e. DDR3) has made the stability of power a pressing issue in today’s designs. The Cadence SPB 16.2 release has addressed this challenge and will make analysis of the PDN a much easier job for IC Package Designers.

An automated flow fueled by Apache’s PakSi-E 3D field solver engine, enables the efficient extraction of coupled power, ground and signal nets.  The extracted models are then used in simulation to check that power and ground voltage variations caused by signals switching simultaneously are within specification.

This topic will be addressed at CDNLive! in Silicon Valley on September 9, so be sure to attend session 81CP2 - Package Design Flow for Multi-Gigabit Devices .
