Simulating 3 phase mosfet bridge with LEDs
If you merely want a visual indicator for port active, then use the Gate drive with series R &amp; LED.   

When you need to verify critical timing, such as deadtime > L/R &amp; RC decay times and prevent shoot-thru, start with dummy load like a light bulb then introduce inductance while monitoring your thermal design with sensors.

I suggest you must include current sensors for feedback on faults.  Consider all aspects of critical unknown and how you will verify it and plan for DFT test design before you make it.

A tungsten light bulb will somewhat simulate the up to 10x start surge of an efficient motor or capacitive load, but without the reactive phase shift.
