Big Chip

Just collected all the documentation together for my latest chip design into a hierarchical PDF... 77 pages of schematics... 12 of them B-size ;-)



If anyone out there is using PSpice Schematics, I learn something new each trip. Found a trick to ease netlisting when you have a HUGE data bus ;-)

Schematics? Did you use tools to generate certain parts or did you draw everything 'by hand'?

Failure does not prove something is impossible, failure simply indicates you are not using the right tools... "If it doesn\'t fit, use a bigger hammer!" --------------------------------------------------------------

I haven't drawn "by hand" since around 1988 (?), when I began using OrCAD (for DOS :-)

(I did surprise myself the other day by drafting, by hand/pencil, a drawing and taking it to a machine shop, where they made my part without further question :-)

I presently use PSpice Schematics v15.7

Besides the normal collection of library parts, I have around 1500 customized device symbols, some of which ease calculation of certain simulation values/performance analyses, etc.

Some of these specialized devices are posted on my website.

Additionally, many of these techniques can be easily imported into LTspice. A recent client checked my work using LTspice, directly importing my netlists. He's now switching to OrCAD Capture :-( which I can also directly export schematics to. ...Jim Thompson

Old buck started late. Young buck started in 1986, using Futurenet Dash-2, later Dash-4. I could have gotten on Racal-Redac a year earlier but it ran as a one-seater on a VAX mainframe and only after-midnight slots were still available, so I passed on that. Really young bucks weren't high on the CAD pecking order in them's days.

I was on a VAX by somewhere around 1977-1980, but it had only Spice

2G6 on it, no schematic drawing packages. ...Jim Thompson
