Electronics Forum / CAD / July 2008Bug in OrCAD Crapture
In OrCAD Crapture, wiring as below... ----.---------------> GND __|__ --- - Wiring from a ground symbol to a port name, the "zero" node effect is lost, giving "floating node" errors and all kinds of nonsensical grief. Cured by inserting a zero-volt voltage source: ----.---------(=)-----> GND __|__ --- - I have a small "(=)" symbol which netlists as a zero-volt voltage source that I use to make node-name-to-node-name connections without losing the uniqueness of each name. ...Jim Thompson | James E.Thompson, P.E. | 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 | | | | America: Land of the Free, Because of the Brave | | | | Due to excessive spam, googlegroups, UAR & AIOE are blocked! | > In OrCAD Crapture, wiring as below... > [quoted text clipped - 17 lines] > source that I use to make node-name-to-node-name connections without > losing the uniqueness of each name. You mean OrCad can't even do that anymore? ----. .-------> GND PORT __|__ __|__ --- --- - - <gasp> Was no problem with SDT.

The problem is so bad in ConceptHDL that they included the symbol to do that - connect two different named nets. In Capture, the only place you really need it is for power and ground nets, where you can't tolerate the name changes...

This was done a few times in my cases since my clients use all kinds of CAD systems, one even AutoCAD (including the schematics). Adds a couple hours of my time to check the results but it sure is cheaper for the client. Beats having to pay for a complete seat plus my training.
