I'm using OrCAD Pspice simulation for my project.. I have encountered a program that says the selected component is undefined..

ERROR -- Model IRF510 used by M_M2 is undefined

Is there any solution for this?

 

Have you created that model by yourself or is it a normal component you picked up from an existing library? (not a library that you've created).

 

I think that the component does not exist in the Pspice supplied library.. I have no idea how to create my own model from Pspice..

 

The error tells you that IRF510 model is missing. Normally, IR offers models for its MOSFETs, but IRF510 was discontinued. I suggest you download from International Rectifier the IRF540 model (http://www.irf.com/product-info/models/SPICE/irf540n.spi), rename it for IRF510, include it in your file, and see if it works. Or, you can call the IRF540 model in your simulation and use the downloaded model.
