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 [...]

Getting subversion and Cadence to play nice together

By Poojan Wagh | Published: August 29, 2008
I wrote a set of scripts to make Cadence IC tools & Subversion work together. This requires subversion 1.4 or higher. Red Hat Enterprise Linux 4 by default ships with 1.3. See also Pictorial Introduction to Using Cadence/Subversion for detailed tutorial on usage. This post is mostly about the guts of the scripts. Note: this [...]

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 [...]
