| * **Note:** The CPU_RESETN button is active-low. This means it behaves differently than the other buttons you have used: it is a ''0'' when pressed and a ''1'' otherwise. You will need to invert the signal when connecting it to your ''stopwatch'' and ''SevenSegmentControl'' modules. | * **Note:** The CPU_RESETN button is active-low.

| - | * In case you didn't notice, the CPU_RESETN button is active-low. Think about what that means before you continue. Failing to grasp the significance of this is one of the biggest pitfalls of this lab. | ||

| - | Attach a video (narrated) describing how your design operates. Time it to show that it really is counting seconds at the correct rate. Show how you can clear it at well and how you can start and stop it at will. Also, describe how long it will take for the counter to completely roll over and show that happening. | + | /* |
| - | </color> | + | =====Personal Exploration===== |
| + | Here are some ideas for personal exploration in this laboratory: | ||
| + | * Use additional switches to make your stopwatch run faster or slower than real-time. | ||
| + | * Modify your design to work as a countdown timer when sw1 is high, and a count-up timer when sw0 is low. | ||
