That was a lot of words to say "custom silicon is currently on the upswing".

Sorry, I could not make it through!

Aside: Although not strictly custom silicon, one can get close to making a custom chip with a Programmable System On Chip (PSoC) made by Cypress who look to have been "consumed". [1]

I did toy with the idea of making application specific "chips" from this system, but couldn't find enough inspiration. The design tooling - last time I looked - was pretty good.

How is that different from a normal FPGA?

They're more like microcontrollers with a small CPLD peripheral. Not enough programmable logic to implement an interesting IP core, last time I checked.

It is FPGA technology alongside analog blocks as well as other pre-defined peripherals available from the design tool. Most pin are unallocated and you drag and drop gates, ADCs counter etc etc and wire them up. If a block can be software controlled it is addressable via the ARM core and one can read hardware state in software.
