There have been FPGAs in the past which used the logic blocks for routing, including the Xilinx 6200. I think that was also the case for the Atmel AT40K FPGAs, but could be remembering wrong.
In fact, our project for the previous Google shuttle was an FPGA-like device which also routes data using logic cells. Here is an introduction to the idea:
https://github.com/fiberhood/MorphleLogic/blob/main/README_MORPHLE_LOGIC.md https://github.com/fiberhood/MorphleLogic/blob/main/README_M...
It worked in simulation and the chip is currently scheduled to be shipped to us on September 6. There were 2 or 3 projects that were more conventional FPGAs.

- jecel 5y agoThere are some common features, but also differences that makes them a bit hard to compare directly. An academic project that takes yet another approach to this design space is: http://cba.mit.edu/projects/rala/ http://cba.mit.edu/projects/rala/
