orcad to ulltiboard

What is the best way to import a netlist into ultiboard from orcad capture?

[Bhavesh]

In OrCAD capture export the netlist to a Calay netlist format. Importing this netlist format to Ultiboard will be your easiest method of going from OrCAD to Ultiboard.

Notes on transfer from OrCAD Capture CIS 16.0.0.p001 to Ultiboard 10.1.197  

 

In Orcad, create netlist, pick tab other, formatter: calay.dll

The output is 2 files: *.net and *.cmp  

If feasible, in Orcad, renumber reference designations before starting

Print out the *.net and the *.cmp files.

 

In Ultiboard, File->New Design

In Ultiboard, File->Open…

Pick Files of Type: Calay Netlist Files (*.net)

Open the *.net file

 

In Ultiboard, in spreadsheet view, pick parts tab. Print using the spreadsheet view print icon. Compare with the *.cmp file printed above. Insure that all the parts and reference designations are there! (The reading of the *.net and *.cmp file doe not always report it could not find / match a footprint.)   

 

Ultiboard expects electrolytic capacitor pin names + and -. Orcad and Calay format uses 1 and 2. In Ultiboard, make a new properly sized electrolytic capacitor footprint but with pin names 1 and 2.

Ultiboard expects diode pin names C and A (for Cathode and Anode). In Ultiboard, make a new properly sized diode footprint with pins named 1 and 2.

And so on.

One has to be careful the parts with changed pin names do not conflict with future Multisim / Ultiboard transfers. Use unique names!  

 

For uncommon parts, compare the expected pin locations with the original schematic and the part’s data sheet.

 

Go over the *.net file. For example, the /GND (digital ground) and /AGND (analog ground) nets, even if connected on the schematic, are separate nets in the netlist.

There is a “net bridge” in Ultiboard to connect nets, but look in the forums for more information on using it.

Since this answer is quite old I would like to get the response refreshed. 

I need to import a netlist from a recent version ORCAD schematic to Ultiboard 14.1.

Is Calay still the preferred ORCAD export format?

Thanks.

I was able to import the calay64 netlist, though no parts came in.  I would have thought any part without a matching footprint would come is as a 'no footprint' symbol, but no parts came in, even those that had matching footprints.  When I added a few parts manually I found there are netlist errors.  i.e. I have a resistor with one pin listed in two different nets, even though the input calay netlist is correct and does have that extra false connection.

It also looks like I can't import a revised netlist into an existing design.  Each new import results in a new design opening instead.

Any ideas?
