Parametric generation
Configurable depth, word width, column multiplexing, and write-mask granularity. SRAM22 generates the array geometry and sizes the decoders and wordline drivers for each configuration.
Physical-design views
GDS layout, LEF abstracts, SPICE netlists, Verilog models, and interpolated Liberty timing for simulation and place-and-route. BWRC builds also support Liberate characterization and DRC, LVS, and parasitic extraction through commercial tools.
Self-timed architecture
Replica-based timing controls the wordline pulse and sense-amplifier activation. A single bitcell array shares precharge, transmission-gate column muxes, sense amplifiers, and masked write drivers. See the control sequence.
