Verilog-A standard function <transition> is not supported #87

Any plan to have the function supported by OpenVAF? Thanks.

I probably won't implement that. Transistion and similar functions are kind of strange because they are not physical. That means that they don't work with small signal and harmonic balance simulations.

That clashes with the model OSDI/OpenVAF uses which is designed around DAE systems. I could make this work by extending the specification with state tracking but that is a fairly large effort that I will probably not take on for personal reasons.
