New question about Netlist errors

[dresslered]

I built a custom OpAmp using the component Wizard and so far have been unable to simulate this component.  I keep getting the errors listed below.  Is the paramater name 'dmos' not supported by multisim?  TIA

Hi,

dmos is an arbitrary name for the model. It just has to match the name used in the circuit instance.

The problem is that there are syntax errors in the model -  a couple of parantheses are unmatched.

Attached is the fixed version.

Thank you MaxNI.  That was indeed the problem.

Hello, I have a problem that seems to be like this in some way.

I've created an ECC83 vacuum tube and tried to simulate it. Surprisingly it works... and works in the correct way, but there is one error:

------ Checking SPICE netlist for ModeloECC83Funcionando - miércoles, 07 de marzo de 2012, 15:46:00 ------
SPICE Netlist Error in schematic RefDes 'u1', element 'xu1': Unable to interpret 'u1_open_x1'

I have no idea about what multisim is trying to say. There is attached a printscreen of the circuit and its pins and the model text file.

Thanks for helping.

I need the actual Multisim circuit file. 

Did you set symbol pins 4-8 to 'NC' (Not Connected) in the symbol-to-model mapping?

[Zung]

I think no. I changed them to NC the first time and I couldn't change to the original value again... then I remade the entire model and the pins were OK.

However, that pins are unused in the circuit I made.

The m11 is attached.

Thanks for your help.

the unused pins are not set to NC. Multisim is trying to connect these to non-existent model pins. 

Edit the component in the database and set all pins expect for P1 G1 and K1 to NC

Thanks

[Zung]

It really worked.

Thank you very much for answering so fast.
