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:
