Software Projects


VerilogAe is a new open-source Verilog-A compiler, purpose-built to ease compact model parameter extraction. It has been developed by my student Pascal as a back-end for our parameter extraction toolkit. VerilogAE retrieves all model equations, their dependencies, and relevant model parameters that are defined in a Verilog-A source file.


COOS is a TCAD simulator targeted at SiGe and III-V HBTs. I am deveoping this simulator in the scope of my PhD thesis, since none of the commercial tools fits my needs.


Ngspice is an open-source spice simulator for electronic circuits. It enjoys high popularity in the open-source community and has a huge number of features that make it attractive for academia and industry.


DMT (Device-Modeling-Toolkit) is a framework intended to enable device-engineers to extract the parameters of compact models. have one unified infrastructure that can be used for: analyzing and collecting measurement data working with TCAD and circuit simulators.
