Simulation Based on Equations! HELP!

[ing23]

Hey Guys! I just subscribed to the forum. I hope anyone will help me out doing my final proyect.

Base on the equations attached, how can I make my design on multisim. I know that I need to use a D Flip Flop and a Counter...

what r u making?

I am only able to recognize this table, even though i dont get what outputs PV,PA,PS,ect... are :

If I were doing this i would write equation for each output, then we can simplify the conditions and form our logic from there....

so the first 2 equations would be:
PV = !(ABCD)
PA = !(ABC) * D

* note signature, just guessing here!

Im making a Traffic Light! Sorry for not described de words. They are in spanish. All I need is the circuit design to simulate in multisim. I dont see it!

Does Multisim have a Logic Synthesis module? Methinks you will have to do it the textbook way... Convert state tables to equations, then choose a logic family, then create a logic diagram implementation of the equations, then enter the logic into a schematic for the simulator...

since you had to do your own truth tables, you may need your own design too,
again, after doing truth tables, we can simplify and resolve what logic is required:

as example ,for this equation:
PV = !(ABCD)
the logic can be formed either way:
1) quad NAND gate
or
2) quad AND gate then NOT gate

Ok I already got the simulation based on D Flip Flop and it works...

I need now to make a counter that controls tha state transitions. And pedestrian crossing button from east to west and north to south
