Yeah, there have been a dozen different attempts to make "an FPGA, but analog". This is one of them. They all failed. You'll note the page hasn't been updated since 02006: https://web.archive.org/web/20060715013941/http://www.anadig.... Analog circuits aren't fungible the way digital circuits are.
I'm not saying it's not a worthwhile research direction, just that it hasn't borne commercially viable fruit so far, despite decades of attempts.
