Libraries of Standard Cells: Main Logic Libraries

SESAME uHD - 6 tracks

TSMC 55 LP, SESAME uHD for ultra high-density logic design thanks to 6-track cells combined with pulsed latch cells acting as spinner cells (densest alternative to flip-flops).


    • Ultra High Density
    • 7% up to 15% denser after P&R compared to standard 7-Track library
    • Pulsed latches as ?Spinner Cells? instead of D-flip-flops: for min. 30% gain in density
    • Metal layer 2 available for routing as only Metal 1 used for cell design
    • 6-Track cells for optimal area reduction
    • Power reduction features
    • 30% less power consumption versus 7-Track library at nominal voltage
    • Low Voltage Capability for additional power savings when operating down to 1.0 V +/-10%
    • Smooth implementation
    • Pulse generation automated by the script for ?Insert pulse generation?
    • Spinner cell design minimizing hold time violations
    • Optimal Design for Yield
    • Design methodology ensuring High-Yield circuits despite Mismatch
