I just saw this and figured that it would be of interest to viewers

> The MPAA020 is a field programmable analog array based on a general
> purpose analog cell that may be configured, either alone or in
> combinations, as any of a wide range of analog functions from simple
> comparators to complex filters.  Looking through the manual (about 160
> pages, downloadable), I see that they have macros set up for designs of
> oscillators, gain stages, signal conditioning, filter stages, rectifiers,
> etc.  Each cell's function may be programmed to connect with any of the
> other cells in the array.  There are 20 cells is the MPAA020 part.
>  Digital interface circuitry is provided to write the anaolg circuit
> configuration data to on-chip SRAM in the same manner as Motorola's
> digital FPGAs.  Analog design is simplified with EasyAnalog (tm) design
> software which handles bit level circuit configuration details, allowing
> the user to do analog design using functional macros in an easy to use
> point-and-click graphical environment.

>  Apparently, you can do your total design with this software without
