Heterogeneous Symbol In OrCAD Capture.

[brucesun]

Hi Robert,

I created a Heterogeneous part with 2 sections like T?A and T?B. But when I incrementally annotated the schematic the references of the part became T1A and T2B. I expected the 2 sections to be T1A and T1B. Did I do something wrong?

Update: I tried the method here but it doesn't work. Also failed this way: https://www.youtube.com/watch?v=sifrtqcE1Rc

I can't try that (I still do not have a new license) and I do not remember exactly, but maybe it was something about Update Occurrences vs Update Instances (in the annotation window)? Did you try that options? But I really do not remember ... maybe I didn't spent too much time with it and just named it manually.

Hi Robert,

I tried both update occurrences and update instances but the results are the same. I will create a footprint for this part and I hope the software will treat these 2 symbols as 1 part but not 2.

Thanks.

I will create a footprint for this part and I hope the software will treat these 2 symbols as 1 part but not 2.

- you can manually change the designator and if you use the same number, then it will be one component

Hi Robert,

I completed the footprint for this part and generated the netlist with T1-1 and T2-2 designators. But the problem is that there are 2 components as T1 ans T2.

If I changed the T2-2 as T1-2 manually and the nestlist generating stopped with errors.

#1 WARNING(ORCAP-36050): No pins are present in PCB1. Ignoring this component in netlist.
#2 ERROR(ORCAP-36003): Conflicting values of following Component Definition properties found on different sections of T1.
VALUE
#3 ERROR(ORCAP-36004): Conflicting values of part name found on different sections of "T1".
Conflicting values: XXXXX_(S1+S2)_XXXXXXXXX_(S1+S2)_TERMINAL
Property values of "Device","PCB FootPrint", "Class" and "Value" should be identical
on all sections of the part.
#4 ERROR(ORCAP-36018): Netlisting cannot complete because of the errors listed above in the session log. Correct the errors and netlist design.

I hid some part specific information with XXXX.

The parts are U1A, U1B - same component U1 with two parts A and B. I do not think you can use T1-1 and T2-2, that is not correct. How did you create your symbol? Could you attach some screenshots?

[brucesun]

Hi Robert,

The T?-1 and T?-2 are added automatically when a heterogeneous part is created and the numeric numbering is selected. It will be T?A and T?B only if alphabetic numbering is selected.

Please see the attached file.

Ah, then maybe T1-1 and T1-2 would be correct (Component T1, parts 1 and 2)?

#3 ERROR(ORCAP-36004): Conflicting values of part name found on different sections of "T1".
Conflicting values: XXXXX_(S1+S2)_XXXXXXXXX_(S1+S2)_TERMINAL
Property values of "Device","PCB FootPrint", "Class" and "Value" should be identical
on all sections of the part.

I changed the values of the 2 parts according to the error information and I can generate the netlist without any issues.

[robertferanec]

So it works now oki?

[brucesun]

Yes. The 2 parts must have exactly the same values.

And after the values of the 2 parts are the same, the auto annotated reference designators are T1-1 and T1-2 as I expected before.
