Setup Pin Constraints Command Dictionary
CX — A literal that specifies application of the constant X (unknown) to
the chosen primary input pins. If the value of the pin changes during the
scan operation, the tool uses the non-return waveform.
R0 period offset width — A literal and three integer quadruplet that
specifies application of one positive pulse per period.
SR0 period offset width — A literal and three integer quadruplet that
specifies application of one suppressible positive pulse during non-scan
operation.
CR0 period offset width — A literal and three integer quadruplet that
specifies no positive pulse during non-scan operation.
R1 period offset width — A literal and three integer quadruplet that
specifies application of one negative pulse per specified period during non-
scan operation.
SR1 period offset width — A literal and three integer quadruplet that
specifies application of one suppressible negative pulse.
CR1 period offset width — A literal and three integer quadruplet that
specifies no negative pulse during non-scan operation.
Where:
period — An integer that specifies the total number of test cycles. The Set
Test Cycle command defines the number of timeframes per test cycle.
offset — An integer that specifies the timeframe in which values start to
change in each period.
width — An integer that specifies the pulse width of the pulse type
waveform.
Examples
The following example sets one primary input to behave as a clock and the rest of
the primary inputs to behave as a constant high signal:
set test cycle 2
add pin constraints ph1 r1 1 0 1
setup pin constraints c1
