 **Hint:**
-AMC characterization relies on SPICE simulations and for large SRAM arrays, characterization is slow. To reduce the characterization time you can trim the SPICE netlist using //AMC/compiler/characterizer/trim_spice.py// file. By timing the SPICE netlist, portions of SRAM array that are not critical during read/write operation will be removed. Trimed netlists can be used for delay calculations. Do **NOT** use trimed netlist for LVS verification or leakage/energy measurement.
