Can someone please tell me how I can create a new PSPICE model? I am trying to modify the existing 1N4148 diode and create a model for a 1N34 diode. Please help me out if you know how to. Also, if you have any documentation that shows how it could be done, please help me out.
1. I already have all the specifications for the 1N34 diode but I am failing to make it work.
2. I am not sure if this matters but I am using PSPICE 16.5 demo version. Does the demo allows to do this or you have to have a full version?
Thanks in advance for your help!
Yes, demo version allows diode modeling.
Here is what you need to do:
Launch Model Editor and do File>NewDo Model>Copy From > Enter new model name and browse to library where you have 1N4148 model and select 1N4148 from listSay OK
Now modify the model parameters as per your requirementSave this library (say new_diode.lib)Use File>Export to Capture part... to create symbol for this newly created model
Place this symbol in schematicBring up simulation setting dialog and add this library(new_diode.lib) under configuration setting TAB in library files
You should be able to simulate design based on this newly developed model
In reply to alokt:
Thanks a lot for your quick reply. I tried this method but I am having a problem finding .lib files. Indeed, all my library are in the .olb files (The 1N4148 diode is located in EVALAA.OLB file). Actually, do I need a .OLB file or a .LIB file? It seems that PSPICE uses .OLB file as a default library file format. If this is the case, how can I create a .lib file from a .olb file if it is possible. I'm so sorry for asking too much!
Again thanks for the provided help.
In reply to Kaka:
.OLB is symbol library, this does not conatain simulation model details. Simulation can be found in EVALAA.lib, this is located at <installdir>/tools/pspice/library
On following the steps mentioned in previous note, first you will create a .LIB file and then you will generate a .OLB (on export to Capture library)
Hope this helps.
