![]() * EQUIVALENT REFERENCE SIMULATION MODEL FAST CASE when i add the output signal to my transient analisis, the analisis results blank and also all other signals will disappear. after the model is in the library, i can put it in my circuit, but it does nothing. I really tried a few times to import the model as you described it. National Instruments - Electronics Workbench Group Again the tedious part is convertign this heirarchical format into a flattened model. Use the Multisim Component Wizard to finish creating the part and map the symbol pins to the top level model pins for the INVERT10 model. So your model will generally look like this.Ħ. Finally you will need to copy the MPEN and MNEN mosfet models from the lvcnom.lib and place these after these. I believe these are used for modeling the package/wirebond parasitics.ĥ. Specifically open up the "so.s" and you will find the package model for the PAK14 model. The "XPAK14" is referencing the PAK14 package model file - these are the "*.s" documents. subckt definition you created for your newly created INVERT10 part model.Ĥ. Copy these parts in their entirety (.subckt to. subckt definitions are found at the top of this 'lvcnom.lib' document. XIN1 relates to the LVCINPAN model, XINV1 relates to the LVCINVAN model and XOUT relates to the LVCOUTODN - these. specifically "XIN1", "XINV1", "XOUT" and "XPAK14" - these are other subckt models that also need to be included within the Multisim model directly.ģ. Notice it references other parts with an "X" reference designator. Open up a new text document and copy the INVERT10 model out of here and into this new document. It looks like the use of different Mosfet models are used to describe the parts operation over the variance of the specification.Ģ. nominal, fast, slow. I'll assume nominal will be preferred (lvcnom.lib). Choose which mode of operation you want to use. Here is what you need to do to get these parts working in Multisim. They can be opened in Wordpad or Notepad - I find the best formatting with Wordpad. These are hierarchical model libraries (*.lib) formatted for Orcad, however they can still be used to create a model in Multisim. ![]() I think you may be missing some model definitions.
