CAS380M17HM3 LTSpice model switching speed

Hi,

I'm simulating a Double pulse test of the CAS380M17HM3 module using the provided model and datasheet parameters for Gate resistance and load inductance. However, I get considerably lower dv/dt values (25 V/ns instead of 50-60 V/ns, as it should be according to the datasheet and experimental tests I've carried on).

Do you have any advice for getting switching speeds closer to datasheet values? (I understand from the user guide that it can be different, but a difference of half the magnitude seems too big)

I attach screenshots showing the parameters and the obtained 40%-60% dv/dt rate as a reference.

Best regards!
