Device Simulator Square Wave

I am having issues with the device simulator square wave generator. I currently have a time-step of 10000 ms. The Square wave function looks like this:

square(0.0,1.0,0.1,true)

Based off what I read in the manual I would expect this to produce a square wave with a duty cycle of 50% and a period of 1 second ranging from 0 to 1. However, I get nothing. I have tried every iteration of this function and cannot get anything to work even remotely close to what I would expect.

Has anyone successfully used these simulator functions or know what I might be doing wrong here?
