The filter designer for windoze was free last I looked (I think you 
have to register on their site for the download). It doesn't do 
anything really impressive, just like the software that Zetex sells for 
TRAC.

The Anadigm stuff is switched capacitor, like most of the configurable 
filter IC, while TRAC is continous time. The building blocks and 
connectivity in TRAC are a bit limiting (don't expect full utilization 
for circuits of any complexity) and the development kit is really 
expensive for what it delivers, but the chips themselves are relatively 
cheap.

Fraunhofer IMS once developed a multiplier based architecture they 
named Analog Silicon Breadboard (ASBB) or Field Programmable Analog 
Device (FPAD). They had working silicon, unfortunately rather noisy, a 
prototype board and rudimentary development software. The tape for the 
second generation product that supposedly fixed the noise issues 
unfortunately never reached mask production.

Motorola had a similar product at one time, which is also not available 
anymore.
