ECE 270 Introduction to Digital System Design Fall 2011 TakeHomaWork for Module 3 – Due Monday, October 3 1. [20 pts] Complete the ABEL file, below, that implements a “dorm-room alarm” system using a 16V8 PLD. Your alarm should accommodate eight sensor inputs, labeled S0 through S7 , plus an ARM input that can be used to arm the alarm. If any sensors are asserted while the alarm is armed, the number of the highest sensor asserted will be displayed on a 7-segment common- anode LED. Note that there are a total of nine (active high) inputs and eight (active low) outputs. In summary, the alarm should function as follows: If the ARM input is negated, the ARMED output indicator should be off and the 7-segment LED should be blank . If the ARM input is asserted but all the sensors are negated, the ARMED output indicator should be on and the 7-segment LED should be blank . If the ARM input is asserted, the ARMED output indicator should be on and the highest numbered input asserted should be displayed on a common anode
