Hello all,In my application,I am trying to develop IGBT using gate driver circuit.

When Im selecting I-V characteristics defined by: 3D lookup table (temperature dependant), Im always getting Ic as 0 in the output. But in the syntax in the "help" documentation is given as zeroes(Vge,Vce,T). I also tried giving different combinations of Ic according to Vge,Vce and T. For example assuming Ic as 2x2x2 matrix .

First combination: [[[0,0],[60,100]],[[90,200],[250,400]]]

Second combination: [[0,0,60,100],[90,200,250,400]]

But nothing works,it doesn't consider as 3D matrix. Then how exactly i should give the values especially Ic so that i do not get just 0s or errors. I have attached the model and datasheet output characteristics.
