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
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
CR0 period offset width — A literal and three integer quadruplet that specifies no positive pulse during
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
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:
