Memory generator generates a synthesizable memory macro by combining the auxiliary cell models and simulation-based optimization of the low-level components to determine the SRAM configuration (#banks, #rows per bank and #columns per bank) accounting the key constraints like performance, power, area and yield. A parameterized verilog netlist is then generated depending on the implementation hierarchy (Figure 1) computed based on the cost function of the performance and yield.

“MEM_GEN” tool that automates the optimization and generation of synthesizable memory satisfying a range of user specifications is developed to achieve a technology agnostic memory design platform. Below are the targeted user specifications of the memory (more user specs are added as the tool matures) for which “MEM_GEN” tool creates the memory TSMC 65nm and IBM 130nm PDK’s.
|Operating Voltage||0.5V – 0.8V|
|Word Size||32 bits and 64 bits|
