Introduction I had been working on a pulse-width-modulation (PWM) design. It was a pseudo-digital implementation, in that the output was clocked by a high-speed clock. The actual switching rate was much lower than this clock. I wanted to simulate this design in Cadence/Spectre by running a transient and then taking an FFT. However, I ran […]

Non-Radix-2 FFT in Cadence/Ocean/Skill/Spectre | Using Cadence IPC to talk to Matlab (or anything else)
However, here’s how I compute SNR/SNDR from an FFT using Cadence Ocean/Skill.
