Set Z Handling Command Dictionary
0 — A literal that specifies to treat high impedance states as a 0 state that
can be distinguished from a 1 state.
1 — A literal that specifies to treat high impedance states as a 1 state that
can be distinguished from a 0 state.
Z — A literal that specifies to uniquely measure the high impedance states;
they can be distinguished from both a 0 or 1 state.
Hold (FlexTest Only) — A literal that specifies to hold the state previous
to the high impedance.
Examples
The following example treats high impedance values as 1 states when they feed
into logic gates, and as 0 states at the output of the circuit, during the ATPG
process:
set z handling internal 1
set z handling external 0
set system mode atpg
add faults -all
run
