Automating pin field modeling for serdes channel simulations

The demands for higher serializer-deserializer (SerDes) data rates dictate the need for more accurate channel models. Assuming that component models are supplied by the vendor, then the printed wiring board (PWB) pin fields are frequently by far the most challenging models for a designer to generate. To greatly reduce the effort required for pin field modeling, automation of the model build process was undertaken. A useful automation script was realized by following a comprehensive set of requirements. Several examples illustrate the utility of this pin field modeling script.
