[Solved] MTS temperature discrenpancy

threepwood06

Hi,

I am trying to use MTS just to compare two voltage values at two different temperatures (same models) in a single testbench.

Here I am simulating a bandgap core voltage vs. temp, so I set one cell to -40deg and the other to 125deg, but the values (especially at -40deg) looks wrong compared to the temperature DC sweep simulation (or even to the DC operating point at -40deg without MTS that matches the value from DC sweep).

In DC OP+MTS, I see a bandgap core voltage =1.216V for -40deg, whereas in the temperature DC sweep simulation I get 1.2257V.

What do I do wrong?

Thanks a lot in advance and best regards

    Ok I've solved the problem: I had to set the model individually for the two blocks.

    Thanks and BR.
