Elevator Floor Request Controller

A 3-floor elevator controller takes floor-call requests (F1–F3) and current-position signals (ATF1–ATF3) and produces MOVEUP, MOVEDOWN, and DOOROPEN outputs. The logic encodes the basic dispatch rule: move toward the requested floor, open the door if already there.

Lo scenario

A digital systems student must implement an elevator controller as a combinational logic circuit from a natural-language specification.

Cosa contiene questo disegno

Leggi le decisioni che ne stanno alla base.

01

Each direction output is the OR of all (request, position) pairs that imply movement in that direction.

02

DOOR_OPEN asserts when the elevator is at a floor that has an active request.

03

Pure combinational design keeps the schematic flat; real elevators add a state machine for queued requests.

Add D flip-flops to queue multiple simultaneous floor requests; extend to N floors by adding more input pairs.
