  Description		  "Triggered Subsystem Demonstration\n\nThis demonstra"
"tion shows the concept of triggered subsystems and what the \ndifferent trigg"
"er types are.  A triggered subsystem is executed for one time step\nonly each"
" time the trigger port transitions from false to true in a certain direction."
"\nThe transition of the trigger port may occur when the direction of the tran"
"sition\nis rising, falling or both rising and falling.\n\nA rising transition"
" occurs when the trigger signal transitions from zero or below\nto a positive"
" value.  A falling transition occurs when the trigger signal transitions\nfro"
"m zero or above to a negaive value.\n\nAfter running the simulation, look clo"
"sely at the top plot in the scope.  This shows\na sine wave, a waveform and t"
"he grounded value of zero.  As the waveform\ntransitions through zero, each o"
"f the subsystems is triggered appropriately.  The\noutput of each subsystem i"
"s equal to the current value of the sine wave at the time.\n\nTo help view ex"
"actly what is going on, you may want to turn the scope crosshair on.\nYou can"
" do this by double clicking on the block that says Scope Crosshair.  This wil"
"l\nenable a set of crosshairs on the scope so that s you move your mouse you "
"can line\ncorresponding values up across the plots."
