Usage
ADD OBserve Points pin_pathname...
Description
Adds observe points to output pins.
The Add Observe Points command adds observe points to the output pins of cells, providing a way to evaluate the effect of making the cell output pin an observable point. After you issue this command, the tool discards all of the patterns in the current scan test pattern set. After insertion, the tool discards the current fault list, so you must recreate the fault list if you wish to perform additional fault simulation. If you enter Setup mode, the tool deletes any observe points you added. Moreover, you cannot generate test patterns after adding observe points.
You use this command primarily for simulating
Arguments
∙pin_pathname
A required repeatable string that specifies a list of output pins for which you want to insert observe points.
