Substrate Parasitic Extraction (SPX™)

Latch up and substrate noise induced by parasitic coupling can have a major impact on circuit operation. They can cause outright failure or lead to unusual power consumption and improper operation. Finding the source of these phenomenon can be extremely difficult without insight into minority carrier injection and transport in the substrate.

Magwel^® SPX™ is part of a methodology to better understand current flows in the substrate. SPX™ is suitable for analog or AMS IC’s, both large and small. Its advanced solver based technology used in conjunction with foundry process data can give insight into the behavior of parasitic Bipolars. SPX™ also provides input for SPICE simulation for modeling the substrate.

SPX™ has been used to solve a variety of difficult problems. Correlation with silicon shows excellent results, even when the design includes biased or floating pockets, wells and contacts.
