Two recently, one is a state machine specification tool that uses a tableview (like excel) and is an executable specification that can automatically generate code and test cases, plus documentaation, originally aimed at functional safety and burner systems, but applicable a far afield as business processes and UI design. It has an OPC server built in so you can interface the simulation with a HMI, or whatever you want.

The other I just got to useable POC last night - making process control Cause and Effects diagrams 'executable' straight off the PDF's.

Both cases I used a mix of python, PyQt, numpy and OpenCV, primarily.

I am an electrical and control systems engineer that primarily analyses and/or designs and delivers control and safety systems.
