LM22678: Buck converter design, simulation stuck on warning "ORPSIM-15256" PSpice For TI

Part Number: LM22678

Hello,

I am trying to simulate LM22678TJE-5.0/NOPB in my buck converter design using PSpice For TI, however, I am running into the following warning and the simulation just stops. This warning seems to be related to the inductor.

Warning: "ORPSIM-15256" (See screenshot below)

I checked the spice model for the inductor and noticed that the values for the six parameters in the warning ("a","Is","L","Z0","F0","EL") is just 0. Is this something I have to talk to the manufacturer (CoilCraft) about or I can do something else in PSpice myself in order to go past this warning issue so that I can get my simulation working? (For example, can I just delete these 6 parameters from the spice model file since I doubt they have any affect?)

Also another question I have is regarding the diode... I downloaded the spice model from the manufacturer's website but had to create the symbol in PSpice. One thing I am not sure about the diode symbol is the number of pins. The diode I am using in my circuit has 3 pins (2 Anode & 1 Cathode). This is also stated in the spice model, however, I was only able to select 2 pin symbol in PSpice when creating the symbol for my diode. Can this create some of issues as well?

FYI:

  • For the inductor in the schematic, I am using model library from CoilCraft (downloaded from their website)
  • I have attached archived zip file of my project for reference.
