SIMULATION

The final step in the design process is simulation. Both functional and time simulations are supported. Photo 3 shows the output pulses at the divide by 500 setting. As you can see, the output pulses are 500,000 timing units apart. I set the clock to have 500 timing units high and 500 timing units low for a period of 1000 timing units. So, output pulses of 500,000 represent a divide by 500.

This is, of course, a brief overview of the software. Itýs free and itýs valuable. It sure beats the text version. And, building a design base is straightforward with this software.
