Work in progress

Here is a list of some of the projects that need to be done. There are many more not listed here.

• Model compiler
• Multi rate
• IBIS

Model Compiler

The gnucap model compiler already makes model addition much easier than other simulators. In general, it does a good job, but there are a few pieces missing. The most significant missing piece is automatic differentiation of the evaluation functions. The gather/scatter portion also needs improvement.

Multi-rate

The highest research priority is the completion of multi-rate transient analysis. This should improve the performance in transient analysis by using different time steps in different parts of the circuit. This research is being done at Idaho State University, in Pocatello, Idaho, USA.

IBIS

I have the code for IBIS support mostly complete except for waveform generation. Some help in comptleting this part would make available the first free simulator with IBIS support. This has been a high priority, but has moved down due to funding issues, simply that the models and model compiler are more important.
