\label{fig:display}
This figure shows the display circuitry for the stopwatch. As shown, the first counter has a modulus of 500000 causing the \textit{cout} pin to go high every tenth of a second when driven by the 50 MHz clock on the FPGA. This is then connected to a counter with a modulus of 10. The output of which tracks the counter and the \texit{cout} pin triggers the next counter. The only tricky part is to make the tens counter for minutes and hours have a modulus of 6 which causes the counter to count 1 minute as 60 seconds.
