NI Circuit design suite component making - errored component behaviour

[BobyCV]

This is where I posted the question some time ago and still waiting for someone to help me.

http://forums.ni.com/t5/Circuit-Design-Suite-Multisim/How-do-I-make-generic-spice-models-work-in-mul...

The component I made using the circuit is behaving erratically and the DC voltage sweep gives a resistor like IV curve rather than diode like IV curve.

This is a huge problem and hence need your support.

Thank you.

My Regards.

BobyCV,

Sorry for this oversight as we do like to see posts answered by users, and if not by a member of our staff (either to answer directly or if not known internally as to point you in the right direction).   I will build and see if I can replicate your circuits behavior as you've mentioned.  I do use Multisim to build 'macro models' from the components - or to modify the behavior of existing macro models such as you have done here.

If I don't see the problem directly, I will work with one of our modeling experts to identify a reason for the response you are seeing.

A good tutorial or reference for many of the SPICE component models is the component refence guide...

You can find this from the Windows Start Menu:

Program Files -> National Instruments -> Circuit Design Suite XX.X -> Documentation -> Component Reference (Windows Help)...

An older document (PDF) is found here: http://digital.ni.com/manuals.nsf/websearch/81AE3340E7A24EB286257260006798F9

BobyCV,

See if this helps to address your problem.   It might be a mapping issue, but the macro model test circuit and the created single Multisim part that I created from the test circuit seem to appear to work correctly.   Often this is a mapping issue related to how the symbol pin names and model pin order are attributed in the final mapping step...

Try this out and let me know if this solves your problem.
