Hi, I'm trying to simulate this circuit on simunlink and I got these two errors on the equivalent model

I'm not sure what is the problem here ; it says "error in port dimensions"

Block error simulink : input is a one dimentional vector with 6 elements

Looks like the problem is in the Universal Bridge. The dimension of 'g' input is expected to be 6 as we have 6 switching devices in a three-phase inverter. However, in the attached image the input 'g' is connected to a Pulse Generator that outputs only a pulse. Probably it is better to use a PWM Generator that would output 6 pulses.
