Title: Synthesis of Analog Modules
Post by krishnap on Dec 11th, 2006, 3:27am

Is it realistic to  synthesize the basic Analog building blocks  like opamp,comparator with
some general design specification and build the library for that particular  process.
It would be great if the flow generates layout (GDS) automatically.

It is possible.  if you have an easy way to take the constraints into the optimization tool (which is what the "synthesis" tool has to be)
The last attempt at this - Barcelona Design's tool, was successful at building OpAmps and even PLL's..
but the time it took to capture the constraints in a form compatible with the optimization engine, and tuning was much less efficient than having a designer iterate the design for a new spec..
Worse, you practically had to start over if you needed a circuit topology not already supported by the constraint sets you had done..
This is the "holy grail" (the object of the "quests" undertaken in Arthurian Legends) of Analog design..

but If you have specs, and a "simulator in the middle" optimization engine with a good RCX extraction tool, and a compute farm you might be able to find some good solutions that you could put in a library..

Not viable with present methods and technology.

Its quicker to have a designer do the design than trying to optimize software to do the job.

A bunch of companies have tried to automate analog design and have failed.
