Dear All,
I am designing robust SRAM memory cells for space application. I have to calculate the minimum critical charge that each memory node can tolerate until data flips.
I run ADE L several times (let’s say around 300-400 times) to find the minimum critical charge and optimum transistors sizes. Each time, I opened up the waveform viewer to check the waveforms. When I found the optimum sizes, I wrote down them and turned off my laptop. The day after that, when I again run ADE L, my saved results were not the optimum! Again, I had to run the simulator several times to find the optimum transistor sizes; they were close to the previous data, but different numbers! I am sure I did not make any mistakes. What can be the problem? Is it a bug?
Bests,
Clik here to view.
