Alpha 21064, 1992, was using domino logic [1]. [1] https://en.wikipedia.org/wiki/Domino_logic https://en.wikipedia.org/wiki/Domino_logic There was no synthesis algorithms that would map VHDL or Verilog designs into domino logic elements at the time. I believe that the most work in the synthesis-to-domino-logic area was done at the beginning of current century. So, DEC's engineers and, I think, Intel's engineers were doing work using schematics well into 21-st century.
