14 nm finFET MERCHANT 1 Gb SRAM STRESS TEST CASE
NO VARIANTS
A preliminary version of a 14 nm finFET gigabit (128 megabytes) SRAM synthetic design/stress test case is available for download now on the Yotta FTP site. It features:

  • 18 nm drawn gate length
  • 65 nm SRAM contacted gate pitch
  • 130 nm by 600 nm single-port SRAM core bit cell size
  • two layers of local interconnect
  • three layers of metal
  • 40 nm fin pitch
  • 2-D gate layer
  • 2-D routing

This design simulates a commercial 128 megabyte single-port SRAM using 10 nm finFET design rules. It is 12,046.3 microns wide and 13,413.4 microns high with a total of 8,569,132,296 transistors transistors.

The family of 14 nm finFET design rules used for this design has an 18 nm drawn gate length, a 64 nm theoretical contacted gate pitch, one layer of local interconnect, six metal layers, 64 nm routing pitches for lower metal layers, and 84 nm routing pitches for upper metal layers (metal 4 and up).

​All transistor gates are vertical; only gate layer routing within standard cells or SRAM circuits can be horizontal.

Because the metal 2 and metal 3 layers allow 2-D routing, they have via doubling. Except for this, geometry on any given metal layer runs in a single direction (horizontal or vertical).

​Design rule variants in this family can have 2-D routing on any subset of gate or routing layers (except metal 1), or diffraction gratings with blockage or cut masks on any subset of gate or routing layers.
