Technology Mapping & Cell Libraries
Generic gates become real, specific transistors from the foundry's catalog.
After generic logic optimization, synthesis maps the design onto the actual standard cells available in a specific process technology's library — often with multiple flavors of the same gate (different drive strengths, threshold voltages, low-power vs high-speed variants) so the tool can pick the right cell for each location's timing and power needs.
