Non-Radix-2 FFT in Cadence/Ocean/Skill/Spectre | Using Cadence IPC to talk to Matlab (or anything else)

By Poojan Wagh | Published: January 19, 2009
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 into a [...]

Pictorial introduction to using Cadence & Subversion

By Poojan Wagh | Published: September 5, 2008
I previously blogged about some scripts I use to help Cadence & Subversion be more compatible. I received some feedback that the scripts were incomplete and came without any usage model. So, I went through an excercise to document the scripts and to make sure they were complete.

Getting subversion and Cadence to play nice

By Poojan Wagh | Published: November 29, 1999
I wrote a set of scripts to make Cadence IC tools & Subversion work together. Note: this is not actual Cadence/Subversion integration (which is much more powerful and highly recommended). There were a few problems that I had to solve: Pesky .svn directories The main problem is that Subversion puts .svn housekeeping directories everywhere. When I’d copy a [...]
