Virtual Mux | Cypress Semiconductor
Virtual mux components are similar to conventional muxes in that they connect a selected input to an output. For a conventional mux, the input selection can be dynamically controlled by a control signal. For a virtual mux, the input selection is determined by an expression that evaluates to a constant when used within a design. The purpose of the virtual mux is to pick one input at build time.
There are two separate virtual mux components: one analog and one digital.
