Error - must be a two terminal device

Pista

I am getting above error when I run Monte Carlo analysis. I have read the PSpice User's Guide but the examples are not clear and do not work either. I think it has a problem with the analysis directives. From the error message I think it is a trivial problem but I could not put my finger on it. Please see below:

*Analysis directives:
.TRAN  0 1.5us 0
.MC 5 TRAN V MAX LIST OUTPUT ALL SEED=101
-------------$
ERROR -- Must be a two terminal device
.PROBE V(alias(*)) I(alias(*)) W(alias(*)) D(alias(*)) NOISE(alias(*))
.INC "..\SCHEMATIC1.net"

I run Orcad 10.5. I would appreciate if anyone could suggest a solution or a reading material with clear examples.

Thanks!

Regards,

  • Check out the PSpice Reference manual, pspcref.pdf in the doc\pspcref directory of the installation. The .MC directive sytax is as follows

    .MC <#runs> <analysis> <Output variable> <function> [option] SEED=<value>

    So, you have #runs, OK; analysis, OK; output variable V, not OK, should be V(<node_name>) for a voltage; function, OK; option, OK; seed, OK. The output variable needs to be defined correctly. (On your fixed spaced console output, the "$" will be under the "V" which is where the problem is)

  • Hi oldmouldy,

    Thank you for the help, it did vork! I had to name the net in question, though, by placing a net alias on the schematics.

    It did not work with "V(R6.2)". When I named that net to "out" on the schematics and defined the 'Output variable' on the 'Analysis' tab of PSpice A/D as "V(OUT), it did work. The suggested reading material is excellent!

    Thanks again!
