Alpha 21064, 1992, was using domino logic [1].

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.

In the early nineties, standard cell design was already used by everyone except those who needed clock speed at all cost.
