Instrumenting adders to measure speed

An SRAM IP Uniquely designed with open source tools. Static RAM is a type of random-access memory that uses latching circuitry (flip-flop) to store each bit. The size of SRAM specs is 32kbit/4k bytes with 1.8v. A 6T SRAM pairs up with two access transistors for read, write state and cross coupled inverter to hold/regenerate the state.

Analog circuit simulation library; wrapper for ngspice
