Temperature sweep analysis problem

[jucimar.carpe]

Hi folks, i'm having problems to plot a simple temperature sweep analysis.

I've created the NTC sensor with the follwing spice program:

.SUBCKT ultimo 1 2 PARAMS: T0=25 R0=10k T1=120 R1=300
R1 1 2 (R0*((R1/R0)^((T0*T1-TEMP*T1)/(TEMP*T0-TEMP*T1))))
.ENDS

The graph should do a Temp vs Tension in a determined point of circuit. Does someone knows how can i correct this?

Hello, jucimar.carpe

I've tried to perform a Parameter Sweep using temperature as the sweep parameter and the problem I've faced here was not to find your NTC temp param. Is that the issue you are having there?
