ORQUAD, OROCT, ORHEXD – Multi-input logical sum

Block SymbolsLicensing group: STANDARD

Function Description
The ORQUAD, OROCT and ORHEXD blocks compute the logical sum of up to sixteen input signals U1, U2, …, U16. The signals listed in the nl parameter are negated prior to computing the logical sum.

For an empty nl parameter a simple logical sum $Y = U1 \lor U2 \lor U3 \lor U4 \lor U5 \lor U6 \lor U7 \lor \dots \lor U16$ is computed. For e.g. nl=1,3..5, the logical function is $Y = \neg U1 \lor U2 \lor \neg U3 \lor \neg U4 \lor \neg U5 \lor U6 \lor \dots \lor U16$ .

If you have only two input signals, consider using the OR block.

This block propagates the signal quality. More information can be found in the 1.4 section.
