Hi all,
also lattice has programable analog which is an ic containing opamps, switched capacitor filters bandgap references and some analog muxes which are transfer gates I guess, and some programable resistors (mux and resistor on chip) and capacitors. They are called PAC, iirc.
Just look it up.
If we want such we can start with a bandgap some op amps like lm324 and a lot of transfer gates like cd4066. With a lot of pins we can connect external components and we may have on chip resistors and matched pair transistors in bipolar and junction fets .
Cheers
Ludwig

Hi best place to ask, Have forgotten the name of a company that has a sea of gates high end
ASIC, you get to do only the one mask, the via layer. Does anyone know the company? It is apparently supported by libre design tools.
So sorry, um I found it:
https://www.easic.com/products/28-nm-easic-nextreme-3/
They are now Intel and not interested in low to medium volume.
Second, somewhere in this talk https://youtu.be/zXwy65d_tu8 is mentioned
an open analog design project, does anyone know what that project is?
Haven't found this one yet
The VIA programmable analog company I know of is Triad Semiconductor with
their configurable IC Technology.
