SESAME HD-BTF rel 1.2 SMIC 130 nm G

 

High density stem

Back-Tracking Freedom capability

Both for Cost reduction

 

 

A library for cost reduction!

Cost reduction in mature technological processes requires that IP providers take divergent paths: high density with standard design rules is a must, but Place and Route also is reduced by Back-Tracking Freedom.
The SESAME HD-BTF library is already celebrated for its twofold cost reduction capability in the standard processes 0.18 and 0.13 µm G, due on the one hand to its RCSL (Reduced Cell Stem Library) structure and on the other hand to its BTF capability (Back-Tracking freedom).
The HD-BTF stem is particularly fit for applications like multimedia players, USB controllers, RFID and GPS/PDA.

 

Positioning & Differentiators

Just like ants, the small cells of the HD-BTF library allow to build complex and highly efficient superstructures


Key benefits of The HD-BTF Stem

  • High density:
    • Up to 20% smaller area compared to the best high density alternatives
    • High Density flip flop: the Spinner Cell
    • Split of Spinner Buffer from Clock Gating enabling a faster clock tree synthesis while ensuring higher density
  • Low dynamic power:
    • Twice less consuming, to reduce the costs of system cooling and power supply component and improve heat dissipation
  • High routability
    • Only Metal 1 is used in layout

 

Sesame Principles

  • Back-Tracking Freedom
    • Capability that eliminates the disruptive loops for fixing timing-critical paths
  • Stem composition
    • The Ultimate flexibility through mixing by synthesizer and Placer and router to enhance either speed or density depending on the design
    • Higher performance in two focused library stems than in a single CCSL even when free
  • Optimal DfY
    • Mismatch simulation of the Spinner Cell system
    • 45 corners validation of the Spinner Cell system
