Standard Cell Library

Our Standard cell libraries include thousands of combinational and sequential logic cells, each optimized for area, speed, power, routability and yield.

Each family of cells is carefully sized, use optimal transistor sizes, P/N ratios, stacking factor and drive strength granularity, with variants that prioritize low-latency, balanced-latency, leakage power and energy efficiency objectives.

To further improve density and routability, our libraries provides multi-bit flipflops and multi-height cells.
