Reply #1 - Nov 6^th, 2006, 6:10am I don't know of a full AMS simulator on PC, never mind a free one. There is a sourceforge project "ADMS" that is a free, open-source Verilog-A only compiler; the developer is hooking it into the "ngspice" project. Last I tried ADMS, there was a fair bit of hassle getting it all working.

Reply #2 - Nov 21^st, 2006, 8:32pm Ken's paper on rapid top-down development with Verilog-A got me interested in this. Is that methodology seeing much use? It sounds like it would be a very quick and sensible way to design any non-trivial system.

Reply #4 - Dec 5^th, 2006, 10:19am I was chatting with someone the other day that said at their company, it's more trouble to do the modeling than it is to jump into a transistor-level design. I suspect this is only true is the design is already well-understood.

I can understand some designers thinking that it will take more time to build up a model than to simply jump into the transistor level. �After creating my first Verilog-A models I probably would have agreed. �But now that I have made a dozen or so models, I am more proficient and I �can make most models in under an hour which is far faster than any transistor circuit even if it is a simple diff pair with a hand full of specs. �The speed improvements in transient sims make AMS worth my time as well.

As an update, there is a "free" simulator being developed as a Gnu project, led by Al Davis,
called GnuCap.. and he is moving it to use verilog-AMS as its NATIVE netlisting language..
the developement version has significant verilog-A support already.
While it will run on a PC - it should probably be running Linux.. but you might be able to run it on OS-X
