Counting the Drivers on a Net
$countdrivers
Counts the number of drivers on a net.
See IEEE std 1364-2001 page 738-739.
Depositing Values
$deposit

overrides the value from any other driver of the net or variable.
The value propagates to all loads of the net or variable. A
subsequent simulation event can override the deposited value.
You cannot use this system task to deposit values to bit-selects
or part-selects.
Syntax:
$deposit(net_or_vaiable, value);
The deposited value can be the value of another net or variable.
You can deposit the value of a bit-select or part-select.
