USER GUIDE FOR THE INPUT WINDOW:

THe Input Widow displays all of the inputs for the selected driver and the
signal values for these inputs. Selecting one of these inputs allows the user
to do one of these fuctions on the selected input:

	Show Connectivity: Selecting this buttons causes the Connectivity
	Window to display the drivers now connected to this input net.

	Display: Selecting this button causes the waveform for this
	net to be added to the Waveform Display window.

The user in back tracing signals in their design to find a design
problem will first "Show Connectivity" for a given signal on the Waveform
Display window, then show all of the inputs for the driver that is activly
driving the signal value for this net. By next selecting one of the
inputs for this driver from the Inputs Window and pressing
Show Connectivity, and then repeating this two step process, the
user can trace backward to any point in their design. Each time a net
is selected and Show Connectivity pressed this net is added to the
Connectivity History window in order to allow the user
to see exactly where they have been in traversing their design hierarchy.

In the input window the order of the inputs are as follows:

For bufif0, bufif1, notif0, notif1, pmos, rpmos, nmos and rnmos 
drivers the top input is the data input and the bottom input is 
the control input.

For cmos drivers the top input is the data input the middle input is
the nmos control and the bottom input is the pmos control. 

For tran and rtran drivers both inputs are data inputs.

For tranif0, tranif1, rtranif0 and rtranif1 drivers the top two
inputs are data input and the bottom input is the control input.
