Hspice and SIC Mosfet models

[elsalty]

I have downloaded several models for SiC mosfets from Rohm and Cree, however I am wanting to use Hspice and these models are not compatible. Some of the obvious things are easy to change (like changes the { to ' ). These models use the .FUNC command to define a function, and then use it in other places. I can't find where hspice supports something like this, but I can just put the function in everywhere it is called. However there is one specific thing that I can't find a way around. All of these models use an "IF" statement. Something like

{IF(V>0,770.4u*V**(8.323*EXP((TEMP-T0)/-899.6))*EXP((TEMP-T0)/33.22),0)}

---

Which I assume states that if V>0 then the equation is equal to 770.4u*V**(8.323*EXP((TEMP-T0)/-899.6))*EXP((TEMP-T0)/33.22), and if V is equal to or less than 0 then it is equal to 0. However I can't find a way to implement this in hspice. I have spent time looking through the hspice manuals but I haven't found anything. Thanks in advance for any help.

Here's an excerpt from an HSPICE manual which explains the .IF .ELSEIF .ELSE function: View attachment HSPICE_if_else.pdf

Does HSpice digest veriloga blocks properly? If so, there
is your flexible simulation language.
