MicroSim 8 error

Bob, Need a lot more information than that. Is this on standard parts, or parts you created yourself? What is the exact wording of the error message, and where are you seeing it? Be sure and take a look at the output file (*.out) and see exactly where it indicates the error...

Charlie

Thanks for replying Charlie,

The MicroSim 8.0 started to show ERROR subcircuit xxxx missing or undefined or just undefined for all semiconductor parts. All parts are from the standard parts libraries. Bilateral switches never did work, showing subcircuit missing.

The same errors show in the message viewer and output file. All semiconductor parts have one or the other error.

Example messages;

Model D1N4148 used by D_D1 is undefined.

Subcircuit TLC4016 used by X_U1D is undefined. This message occurs for any bilateral switch tried.

The latest simple circuit was working with a MOSFET. When the MOSFET was replaced with a bilateral switch the subcircuit missing message occured. Since then all semiconductors return a either a model or subcircuit undefined.

Hope you have an idea about how to solve this.

Bob, Ok, take a look at your simulation settings, especially your setup options, and make sure that nom.lib is listed. Plus, you need to make sure that any other simulaiton libraries, other than the standard ones, are listed there as well. This error basically says that, in none of the configured libraries, is a model with name XXXXX defined.

Got it Charlie,

Added nom.lib* to library files in library and include window. That was accepted except for a subcircuit undefined error for the TLC4066.

Had to go back in and specifically ad the Ana_swit.lib file to run a simulation without errors. The library and include has only the circuit file, nom lib*, and ana swit* files in the library files window. Is this normal?

Why aren't all the "lib*" files automatically loaded? Do you want to add them all, and if so how? Select all?

Thanks,

BobS

Hi Bob, Normally, they are all loaded, but sometimes, you do something, and you erase it or remove it, and then you have problems like what you saw. The usual problem is that you create a new part, and add the symbol library, but forget to add the model library.

The reason you don't see libraries added automatically, is because some users have multiple model libraries for the same parts. They use different versions of the model depending on what simulation they are performings, such as an AC sweep, or transient, or even Monte Carlo vs. standard transient...
