Adding Instructions

These options are all available by clicking the add instruction buttons on the toolbar.

Generate

Generates a named waveform. You can generate the entire waveform or a subset of it. You can also choose to generate a marker at a specified location in the named waveform. For example, to generate a marker at the 150th sample of the waveform, type 150 in the Marker 0 textbox.

Repeat

Repeats a set of instructions. You can repeat a finite number of times, repeat forever, or repeat until a hardware Script trigger is received.

If/Else/End If

Determines what sections of a script to execute, based on whether a particular Script trigger was received.

Wait

Pauses execution until a Script trigger is received.

Clear

Ignores a previously latched Script trigger. This option is typically used before the wait or repeat until instructions. For example, if the two instructions in myScript are:

script myScript

generate mywfm

wait until scriptTrigger0

end script

The Script trigger may arrive when mywfm is being generated. So when Wait until scriptTrigger0 is called, it is executed after the shortest possible delay. If you wish to ignore previously asserted Script triggers, then use the clear instruction:

script myScript

generate mywfm

clear scriptTrigger0

wait until scriptTrigger0

end script
