I am interested in simulating the ADA4817 op amp. I have downloaded the SPICE model. When I try to run it in Altium I get the following errors:

I assume that the Altium XSpice is not compatible with the Pspice format. What I need to know is how can I manually modify the file to be acceptable (the "t_abs" does not seem to be readable by Altium)?

 

I realize that I can use the analog devices  multisim, but we really need to do our simulation within the Altium environment.

 

Thanx,
