Table 14-3: Provisional Boundary scan AC parameters (units in ns)
The AC parameters are based on simulation results using 0.0pf circuit signal loads. Delays
should be calculated using manufacturers output derating values for the actual circuit
capacitance loading.
The correspondence between boundary-scan cells and system pins, system direction controls
and system output enables is shown below. The cells are listed in the order in which they are
connected in the boundary-scan register, starting with the cell closest to TDI. All outputs are
three-state outputs. All boundary-scan register cells at input pins can apply tests to the on-chip
system logic.
EXTEST/CLAMP guard values specified in the table below should be clocked into the
boundary-scan register (using the SAMPLE/PRELOAD instruction) before the EXTEST,
CLAMP or CLAMPZ instructions are selected to ensure that known data is applied to the
system logic during the test. The INTEST guard values shown in the table below should be
clocked into the boundary-scan register (using the SAMPLE/PRELOAD instruction) before the
INTEST instruction is selected to ensure that all outputs are disabled. An asterisk in the guard
value column indicates that any value can be submitted (as test requires), but ones and zeros
should always be placed as shown.
