ARM Artisan Standard Cell Libraries are available from the latest advanced 28nm nodes to established mainstream 250nm nodes. These are "best in class" libraries based on architectural analysis by experts in leading-edge processes and design styles. The libraries include models for successful implementation across the entire design flow, from synthesis to tapeout. ARM processors and other IP use the ARM Standard Cell Libraries for reference and benchmark designs.

Wide performance range for all types of designs

  • Ultra high density/low power; 7 or 8-track (SC7/SC8) libraries for cost critical applications
  • High density; 9 or 10-track (SC9/SC10) libraries for mainstream applications
  • High performance; 12-track (SC12) libraries for speed critical designs

Footprint compatible multi-channel length (MC) and multi-Vt libraries

  • MC libraries enable the combination of high performance with ultra-low power
  • MC leakage reduction proven in silicon
  • MC libraries provide higher yield than competing solutions
  • Available for different performance ranges
  • Use multi-Vt flow for MC libraries; no special design flow

ARM has a successful history of library development and takes the forefront in cooperation with foundries, customers and EDA vendors. Such alignment, across key disciplines within the industry, results in continuous improvements in cell sets, architecture and modeling, all of which are proven in thousands of designs.


ARM Standard Cell Libraries are for use in ultra-low power designs in the MHz range up to multiple GHz in performance critical applications. 
  • Variety of architectures based on different track heights and cell designs cover a wide performance, power and area range
    • High Performance libraries are 20% faster than High Density mainstream libraries
    • Ultra High Density versions based on smallest cell height require 20% less area and power than mainstream libraries
  • All libraries are silicon tested at various voltage and temperature conditions and correlated with library models
    • Low voltage Si verification ensures functionality at low power applications

Very large cell set to ensure optimal implementation of all types of design

  • 1250 cells per Vt or channel length at 32/45 nm
  • Smaller cell set in more mature technologies
  • Wide variety of specialty cells like clock gating cells and decoupling capacitors

Optimized cell set targeted performance range/applications

  • Hand tuned and handcrafted cell designs for highest density and routeability 
  • Multiple beta (P:N) transistor ratios for performance - power tuning
  • Tapless cell design for all libraries at 65nm and smaller geometries as well as for selected 180 to 90 nm libraries
  • 65nm and larger geometries use M1 power rails
  • 45nm and smaller geometries use M2 power rails for optimal support of restricted design rules
  • Strain optimized layouts for high performance libraries in selected process nodes

Leading edge design flow and model support

  • CCS timing, noise and power, ECSM, Voltage Storm, Celtic and other specialty models 
  • Latest DRC rules and electrical models  

Extensive set of PVT corners

  • Multi-Vdd characterization
  • Overdrive voltage support
  • Support for temperature inversion corners
  • High leakage corner (standard at 90 nm and below)
  • Custom PVT support
