EPC2088 Pspice Model is Not Working

Designing with GaN FETs and ICs Modeling and Simulation
1

I am designing a boost power supply using the EPC2088.

I usually copy and pasted the text format of the library into the LTspice to ensure portability of the file, and ensure that correct symbol and syntax were done on the component.

It seems that the spice model is not working

This is the circuit below:

This is the error that I received when hitting run:

This is the syntax of my symbol:

I would really appreciate your help on this one as it will help me in using your product for the reference design that I am currently working on.

Let me know if you need additional information

Hi John,

(1)From your attached file, the EPC2088 GaN run the LTC7893 simulation in LTSpice is error message removed in my environment,

Some circuit behavior is incorrect and command issue when run the circuit show as below :

It is the correct EPC GaN Lib when simulated with example file from LTC website :

LTC7893 Datasheet and Product Info | Analog Devices

We can talk more if you want to have time to discuss the design.

Best Regards
