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 $\mathtt{\text{Y}}=\mathtt{\text{U1}}\vee \mathtt{\text{U2}}\vee \mathtt{\text{U3}}\vee \mathtt{\text{U4}}\vee \mathtt{\text{U5}}\vee \mathtt{\text{U6}}\vee \mathtt{\text{U7}}\vee \dots \vee \mathtt{\text{U16}}$ is computed. For e.g. nl=1,3..5, the logical function is $\mathtt{\text{Y}}=\neg \mathtt{\text{U1}}\vee \mathtt{\text{U2}}\vee \neg \mathtt{\text{U3}}\vee \neg \mathtt{\text{U4}}\vee \neg \mathtt{\text{U5}}\vee \mathtt{\text{U6}}\vee \dots \vee \mathtt{\text{U16}}$.

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.
