Standard Cell

A pre-designed, pre-characterized logic cell used as a building block in ASIC design.

Detailed Explanation

Standard cells are library elements—gates, flip-flops, muxes, and complex logic functions—designed for a specific process. Cells have uniform height (for row-based placement) and multiple drive strengths. Libraries include timing, power, and noise models.

Synthesis maps RTL to standard cells. Place-and-route positions cells and wires them. Standard cell methodology enables automated design flow, unlike full-custom design where each transistor is individually placed.
