The Setup Output Strobes command sets the default strobe point for all output
waveforms. Keeping the test cycle in mind, you should specify a time before the
clock is active, but after the output data is stable. Typically, you should not strobe
at the clock edges if the design contains latches, because timing problems could
result.
ADD INput Strobes number input_list
The Add Input Strobes command changes the sampling time of one or more
specific inputs from the default value to the specified number. Typically, you
would use Setup Input Strobes to set the strobe time for all inputs and only use this
command if you had a special case that required strobing a certain pin at a
different time.
ADD OUtput Strobes number output_list
The Add Output Strobes command changes a particular output sampling time
from the default to the specified number. Typically, you would use Setup Output
Strobes to set the strobe time for all outputs and only use this command if you had
a special case that required strobing a certain pin at a different time.
ADD INput Clocks format strobe1 strobe2 input_list
The Add Input Clocks command sets the clocks’ format and strobe points. The
available format literals are R0, R1, SR0, SR1. The strobe points sample the
waveform and perform error checking. Strobe1 must occur when the clock is on
and strobe2 must occur when the clock is off. For the SR0 and SR1 formats, if the
two strobe sample points have different values, there is a pulse in that cycle. The
utility error checks all formats to make certain that the pulse matches the format. It
issues a warning if it encounters any inconsistencies. Thus, the stimulus generated
in FlexTest table format is guaranteed to be correct. For instance, if the input
stimulus for a R0 waveform is missing a pulse in a cycle, FlexTest requires the
translator to insert one.
