That's how all chip design works today. Except we write code, not
schematics. Code - VHDL/(System)Verilog, higher level hardware description
langauges like Bluespec and Chisel - scale better than schematics.
The compiler takes that and produces a netlist of 'gates' (often more
complicated things than regular logic gates, eg lookup tables, adders,
memory elements and such) and the place and route tool decides how to pack
them onto the chip (either laying down transistor shapes for an ASIC or
fititng to existing structures as on FPGAs) and wire them up.
