1.1 Modify the signal using draw, hi-z, and bus tool

	- Draw Icon
	- Hi-Z Icon
	- Bus Icon

The draw icon   allows you to draw a high or low value onto the waveform. Using your mouse and the left mouse button, click and drag your mouse on the upper half or the lower half of the signal to create high or low transitions.

The Hi-Z icon   allows you to draw a high-impedence or middle line onto the waveform. Use your left mouse and click on the cycle that you want to draw in the middle (neither high or low).

The bus icon   allows you to draw a bus transition (both high and low at same time). Click your left mouse button onto the cycle that you want to create the bus transition. If you want to clear a bus transition, then click on the cycle twice.
