Power mosfet model for spectre

[Sergio Gascón]

I am designing a circuit in Cadence using spectre but I want to
simulate an extermal power mos which model is not included in the
foundry kit (obviously). The mosfet is the irf3315 and the only model
I have found is a very simple model to be used in pspice. This model
could be enough for these first step simulations but I am not familiar
with model conversions and there are some lines I do not know how to
translate:

FI2 79 VFI2 -1
VFI2 4 0 0
EV16 10 0 9 7 1
FI1 7 9 VFI1 -1
VFI1 11 6 0

If anyone could give me a hand with the meaning or translation of this
lines it would be fantastic. A model suitable for spectre would be
even better but I think it is impossible.

Since I see a similar device below listed correctly I presume a typo
here and it should be

FI2 7 9 VFI2 -1

This is a current-controlled current source, output is from node 7 to
node 9, "current measuring" voltage source is VFI2, and gain is -1

VFI2 4 0 0

Voltage

EV16 10 0 9 7 1

Voltage-controlled voltage source, output at nodes 10,0, input at
nodes 9,7, gain is 1

FI1 7 9 VFI1 -1

Same device type as FI2

VFI1 11 6 0

Voltage source

lines it would be fantastic. A model suitable for spectre would be

Sorry I can't help with the model for an IRF3315, I don't see it in my
PSpice libraries at all.

I love to cook with wine. Sometimes I even put it in the food.

Thanks for your help.
