 |
|
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.

Not a problem with PSpice Schematics either. Only caught it when I

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.
