In our prior study of an L-bit priority encoder (PE), a so-called one-directional-array to two-directional-array conversion method is deployed to turn an L-bit input data into an M × N-bit matrix.

Petri Nets (PN) modeling has been proposed as an alternative to Ladder Logic Diagram (LLD) modeling to program complex programmable logic controllers (PLCs) due to its high level of abstraction and ...
