Modeling application enables designer to quickly develop models during the schematic entry phase. You can generate a model and place schematic components associated with the newly created model, without having to get out of the schematic entry interface of OrCAD Capture. These modeling applications also take care of simulation profile configuration and automatically include newly created libraries in the simulation profile to ensure successful simulation.
For example, if you want to simulate a capacitor with a parasitic, you can directly specify the electrical information from the datasheet to generate the required model and place it on the schematic.
Modeling application also supports use of expressions to define model parameters.
