Start with a Square signal and then you can drag and drop any part of the signal lines to make whatever you want.

There are some keyboard shortcuts that will be useful to know if you want to manually modify the waveform. See: http://www.mathworks.com/help/releases/R2011b/toolbox/simulink/ug/f15-109640.html#f15-109779.
You could also choose the 'Custom...' option and enter time and Y vectors, such as [0 1.5 1.5 2.5 2.5 5.2 5.2 6.2 6.2 8] for time and [0 0 1 1 0 0 1 1 0 0]

@Doug, Thank you for sharing the link. That's quite useful. I've tried "Custom..." before and found it impossible to make a straight rising or falling edge.

The trick there is to repeat a value in the time vector like I mentioned above. If your time is [0 1 1 2] and your value is [0 0 1 1] that will create a rising edge at 1 second.

That is weird but good! I thought I tried before but it was telling me that the time stamp needs to be strictly incremental. Thanks, Doug!
