Each circuit was simulated and optimized through three sequential scenarios: nominal (1), realistic (2), and optimized (3). In the first scenario (gray box), the MemSim+ nominal model was used along with the selected design parameters to ensure the overall output was 100% correct. Next, the circuit was simulated again with the same design parameters while using the MemSim+ variability-aware model in the second scenario (red box). When considering the device variability, the simulated output in the second scenario dropped significantly from 100%. Therefore, the third scenario (green box) was engaged to maximize the overall output correctness by iteratively optimizing the design parameters.
