If one is doing an analysis over a range of variables, one should use the paramAnalysis ocean function. That said, I’m constantly having to look up how to do a for loop in Skill. So, I’m placing a couple examples where I know I can get to them.

Skill File I/O
I keep having to look up file I/O using Cadence’s SKILL language, so I’m putting it here for easy reference
Updates to Cadence/Subversion (CDSVN) scripts
Our Brazilian Friends PCS and NGJr have offered the following changes to the CDSVN package: Into the file “cdsLibMgr.lib” was created the menu item “SVN Unlock Cell” Into the file “svnLockCell.il” were created the procedures “svnUnlockCell” and “svnUnlockCellFormCB” Inside the procedures “svnUnlockCellFormCB” and “svnUnlockCVFormCB” were made the following changes: where you have: if( !(rexMatchp(“.*.svn$”, file~>readPath) [...]

My other blogs & plans for the future
It used to be that I’d post just about anything here. However, after a few months of posting circuit design articles, I developed a consistent readership and decided that most of you aren’t interested in my daily life and/or the tech hobbies that I might be up to. As a result, I separated my personally-centered [...]
Tunable Non-Foster Match Using Switched Capacitor
What’s even cooler about this reactance is that the Non-Foster region is determined by the switching frequency–so, one could move it around just by changing the switching frequency. You’d effectively have a digitally-tunable antenna.

Median vs Mean
I’ve been doing some statistical measurements lately (more to follow). It occurs to me that while most people measure the mean of a set of measurements, the median is more useful.

CircuitDesign.Info: Site maintenance
Some of you may have noticed that the site was down for a day last week. Expect a bit more down-time: I’m going to do a bit of experimentation to ensure that future down-time doesn’t happen again (improve reliability).
The benefits of differential circuits
Introduction From my personal blog: I’ve been lucky enough to find myself in a team that’s intent on finding the best circuit design for a given application. This doesn’t happen often to many people, but I feel that I’ve had more than my share of this opportunity. The conclusion is usually that we come up [...]
