Hi, first time posting here. I need help with my assignment. My assignment is to create Traffic Light Controller that has lights cycle through Red-Yellow-Green continuously. The design is made of two sub-systems that work as follows:
3-bit Asynchronous Counter that continuously counts from 1-6
The Combinational Logic Encoder takes the count from the 3-bit Asynchronous Counter and drives the Red, Yellow and Green lights as follows:
-The Red light will be on when the count equals 1 or 2
-The Yellow light will be on when the count equals 3 or 4
-The Green light will be on when the count equals 5 or 6
Design Specifications:
Combinational Logic Encoder needs to include K-Map for each output (Red, Yellow and Green)
The logic for the RED output may only use 2-Input NOR gates
The logic for the YELLOW output may only use 2-Input NAND gates
The logic for the GREEN output may only use 2-Input AND, 2-Input OR and Logic Inverters
Problem:
I already got the first part, which is creating the circuit that counts from 1-6. Here's what I need help on: I don't know how to start the K-Map and I don't know how to create the Combinational Logic Encoder. Also, the software we're using to create this is Multisim.Thank you.
