I'm trying to design an asynchronous counter using 6 T-flip flops. It is giving a reasonable output but of course with alot of delay. I am going to use some combinational logic for the exact divide ratio i require. I havent done it as yet,have just simulated the 6 flops feeding into each other. Am using Specter to do this
What are the timing considerations i need to look at. How do i know if the circuit is working properly. What should be my setup and hold time requirements. I dont have any given reuqirement so how do i determine it. How is it related to my propagation delay. Any help with these questions and any others i've missed regarding this design approach is greatly appreciated...
