How to use "Virtual IO loopback" (e.g. to use PWM modulator) in TyphoonSim

Question

Hello,

I've created a blank DC/DC converter model including the PWM modulator component. This block has no output, help says 

In TyphoonSim, component outputs can be individually routed through virtual IO loopback

I did find the help page "Analog/digital IO loopback" which contains too much data for a HIL-device-less TyphoonSim user, but which says reassuringly

When using TyphoonSim IO loopback is always enabled.

...

In TyphoonSim, digital and analog signals are read from the internal virtual IO bus and can be individually routed. Hence, if some signal is sent to digital/analog ouput 1, it will appear on                digital/analog input 1.

Also, in the Digital Input help it says again "In TyphoonSim, component outputs can be individually routed through virtual IO loopback."

However, in the end, I didn't find how to route the PWM generator switching signal to the gate input of a Mosfet switch. I tried to use the Digital Input set to "Input 1", but this had no effect. So what is the correct approach?

Best,

Pierre

Hello Pierre,

You can achieve this by configuring Output Settings component from System category. There you can assign PWM Modulator signals to digital outputs that will be looped back virtually to digital inputs in TyphoonSim.
