sram compiler

**SRAM Compiler** — a tool that automatically generates custom SRAM memory blocks with specified dimensions, port configurations, and timing characteristics. **Why Compilers?** - Every chip needs memory (caches, buffers, register files) - SRAM layout is highly regular but must be tuned for each size and port count - Manual design for every needed configuration is impractical - Compiler generates layout, netlist, timing models, and verification views in minutes **Configuration Parameters** - Word count (depth): 64, 128, 256, 512, 1024... - Word width (bits): 8, 16, 32, 64, 128... - Number of ports: 1RW, 1R1W, 2RW (trade-off: access bandwidth vs area) - Mux factor: Column MUX ratio (affects aspect ratio) - Voltage and timing corners **Generated Outputs** - GDSII layout (physical design) - Liberty .lib (timing/power characterization) - Verilog behavioral model (simulation) - LEF (abstract layout for PnR) - DRC/LVS clean guaranteed **SRAM in Modern Chips** - Apple M4: ~40% of die area is SRAM - GPU register files, L1/L2 caches, buffers everywhere - SRAM bit cell: 6T (standard), 8T (read-disturb free), custom (high-density) **SRAM compilers** are among the most valuable IP deliverables from a foundry process development kit (PDK).
