Hi All,
 I need to learn how to write a functional model for an analog-front-end core of a larger chip.  It's a random assortment of op-amps, PGAs, LPF & HPFs, equalizers, S/H &  max/min detectors, etc.  The model will be used in an verilog digital regression environment, getting its input stream directly from files of real numbers.

I'm a decent spice & verilogD hacker,  and I can do floating-point emulations of simple analog stuff in verilogD.  But I've never used the analog side.  Where do I start to educate myself?  I'm not even sure of the difference between verilogA and verilogAMS.   Is verilogA an historical term now, superceeded by verilogAMS?

I could probably get my company to send me to a training class where I could enjoy some of Cadence's excellent meals, but I would prefer not to commit a week away from my desk to this effort.

A general question, I know...  But I appreciate any advice you could give me.  Cheers!
