A long, long time ago, in a galaxy far way, or some reasonbly close approximiation thereof, a dear friend of mine Pat Davis (a world class PCB Designer at Millennium Design) started having problems with his EDA and CAD systems. Oddly enough, I'm one of those people who is equally well versed in both causing and solving problems, so I started fixing things for Pat... This is how I first got involved with EDA and CAD software.
As Pat would come to eventually say, "If you never want to do a repetitive task ever again, just tell Roberts to do it twice and he'll automate the heck out of it." This personality flaw of mine led to vast swaths of useful source code, primarily written in the Cadence SKILL programming language for the Cadence design platform. The resulting code is what I am (slowly) organizing into what will be known as the DesignTools project.
The code within the "project" was started long before I ever made it public and well before I ever had the idea of making a "project" out of it. The date you see above is when I started coding the web site framework used to generate the HTML that is sent to your browser. Though the framework is far from finished, it's functional enough to be used.
