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.
