Invalid subckt definition name

musicholic — Fri, 30 Jul 2010 04:28:14 GMT

Hi, guys

I imported CD4046 spice model which is used in Cadence capture program into Multisim.

However, I got an error message, I don't know what it is.

Here is the message.

And also, when I import the model, model pins were not matched with datasheet. Thus, I rearranged the model nodes in edit component in DB.

However, on schematic page, pin numbers didn;t change. Is that okay?

SPICE Netlist Error in schematic RefDes 'u1', element 'xu1': Invalid subckt definition name '0'

The issue is that there is no SPICE model attached to your component. If you have already created the model in Multisim, you need to link it to your component.

To do this:

Double-click on the component to invoke its properties
Click Edit in DB
Select the Model tab
From here, you can select Add/Edit to link the model to the component
Once you are done, map the model nodes according to the pinout in the model

To add the model in Multisim, go to the User Database and select Add once you're in the Select a Model dialog. If you're still having issues, let us know.

I am already done pin mapping, but I am not sure about user database.

I cannot find user database tab. Where is it?

When you open the Select a Model dialog, you will see the various databases to select from there. There should be Master/Corporate/User available

A model is already added. Model data as well.

But I have sitll that problem.

When I double-click on the component and go to the Model tab, the model data is EMPTY and that the model is a lossless transmission line. Here's what I see exactly:

Do you see something different?

I've attached what I seeing, and also ms11 file again.

Unfortunately you won't be able to import this netlist since it's a particular digital syntax that Multisim does not support. Multisim supports SPICE/XSPICE/Pspice(analog) syntax, but not this particular digital syntax.

Oh, I see.

Then, don't you have any Phase lock loop model?

Hi,

Yes! You will find the PLL_VIRTUAL that can be customized based on the component's paramaters in the Mixed Group > Mixed Virtual family.

There are also customers who have created their own in the past. If you search the forums you'll find similar threads on this topic.

Hope that helps!

Natasha

I also found a PLL for Multisim that approximates the modeling of a CD4046 uploaded by a user on Kittmaster's Component Database:
