ORPSIM-15141 after including model from ICA

Falessio

Hi, 

I revived an old project (>8 years old) in SPICE to make an alternative design for a future application and I started porting everything to OrCAD Capture CIS 16.6. Some things I'll keep, some I'll change. I have not been using PSPICE or similia for about the same time now and I feel like I lost the touch and I am stuck on a problem which I simply can't solve.

Simply, I want to include in my schematic alternative chips to the ones I had in my previous design and they are not in my local database (nor in my previous project). I'm therefore using the ICA to get the models. Everything goes fine until I want to simulate the thing. It always complain with the "ERROR (ORPSIM-15141) : Less than 2 connections at node bla bla". It does it for ALL (and only) the chips I get from ICA, I am surely doing something wrong, but I simply can't get around it.

My last resort is to generate the chip myself, but as we are talking O(100) chips, I think that is not very practical... What do I have to do in between "placing part in schematics" and "connecting then simulating"?

Hope I was clear and thanks for any help.

  • Hi oldmouldy, 

    thanks a lot for you answer. First of all, I'm a little surprised that if I get a schematic model from ICA, it doesn't automatically attach (or download with it) the specific PSpice properties. I mean, what's the point then? If I have a specific component then I still have to get the underlying model from the website, then what is the point to use the ICA at all? 

    In any case, you anticipated the second part of my question, because I already did what you said. After a quick search on the net about the criptic error message, I realized the problem was the missing underlying model. I tried what you said. I went on the manufacturer website, I got the model, I tried to link them (like I used to do in the far past), but it just did not work. If I click on Edit Properties, I see everything as it should (I think). I see the library model (.OLB), I see the PSpice Model option, I just don't see the PSpice Template. 

    So, what I thought of doing was to go and get the model from the manufacturer website as I said. I went to ONSEMI (in one specific case I need a PECL->LVPECL translator, MC100LVEL92DW) and in ONSEMI they have only IBIS library. OK, then now 16.6 allows for IBIS translation, so I did it with Model Editor. Created the .lib, then I tried to link the .lib to the .OLB, obviously did not work. So I created to generate the .OLB from the .lib, but it creates three symbols with just an INPUT each and nothing else which I can't do anything with. ON top of the fact that my part has 20 pins and the IBIS model shows only 6 so I can't even map the .lib to the .OLB from ICA, but that is a different question...  

    Any other suggestion how to go about? I really need to fix this because I need to put other 100 chips in my schematics and most of them are on the same line, so I need a "functional trick" for this. 

    Thanks a lot.
