Tip of the Month
Writing your own UDMs
Here is a list of tutorials and documentations that can help you get started with writing your own user-defined models (UDMs) and generating the functional models of your choice from circuits.
Q&A of the Month
The leakage in the 'switch' primitive
For numerical stability, XMODEL adds GMIN resistances to the nodes with no DC path, which may cause leakage in some of the off-state switches. Here is a tip on how to avoid it.
