FlexTest Specifics:

If the value of the pins change during the scan operation, FlexTest uses the non-return waveform.

R0 period offset width (FlexTest Only) — A literal and three integer quadruplet that specifies application of one positive pulse per period.

SR0 period offset width (FlexTest Only) — A literal and three integer quadruplet that specifies application of one suppressible positive pulse during non-scan operation.

CR0 period offset width (FlexTest Only) — A literal and three integer quadruplet that specifies no positive pulse during non-scan operation.

CR0 (FastScan Only) — A literal that specifies a constant that returns to 0; FastScan uses this constant only when formatting the patterns. The ATPG process treats CR0 as a C0.

R1 period offset width (FlexTest Only) — A literal and three integer quadruplet that specifies application of one negative pulse per specified period during non-scan operation.

SR1 period offset width (FlexTest Only) — A literal and three integer quadruplet that specifies application of one suppressible negative pulse.

CR1 period offset width (FlexTest Only) — A literal and three integer quadruplet that specifies no negative pulse during non-scan operation.

CR1 (FastScan Only)— A literal that specifies a constant that returns to 1; FastScan uses this constant only when formatting the patterns. The ATPG process treats CR1 as a C1.

Where:

period (FlexTest Only) — An integer that specifies the period in terms of the total number of test cycles. The Set Test Cycle command defines the number of timeframes per test cycle.

offset (FlexTest Only) — An integer that specifies the timeframe in which values start to change in each cycle.

width (FlexTest Only) — An integer that specifies the pulse width of the pulse type waveform in number of timeframes.
