6 track Ultra High Density standard cell library at TSMC 55 nm

Overview

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).

Key Features

  • 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
