Big Chip

Started by Jim Thompson October 19, 2009
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 ;-)

Drop me an E-mail if you want info.

I love to cook with wine.      Sometimes I even put it in the food.

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...

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 -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Cranky Old Git With Engineering Mind Faster Than a Speeding Prissy

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. [...] -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

I was on a VAX by somewhere around 1977-1980, but it had only Spice 2G6 on it, no schematic drawing packages. ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | Cranky Old Git With Engineering Mind Faster Than a Speeding Prissy
