Hi there, My group and I are currently working on a school project and are having some troubles. We can't currently find any models for the parts of a project that we are working on and were curious if it was possible to create the models based off of the datasheets? These are the parts that we are using and were unable to find any PSPICE models for. Any suggestions or comments would be greatly appreciated. Also if we were able to find models for some other program, besides PSPICE, would there be a way to convert those models over to something that PSPICE would recognize so that we can actually get some simulations done?
