public interface TriStateDriver

This interface allows a class to implement tri-state behavior. For now, a tri-state driver should be used only in the simple case of a single output (of any width) controlled by a single bit enable.

Method Summary

boolean

isDrivingOutput() Must be implemented to state whether the cell is driving the tri-state output, based on the enable input.

Method Detail

isDrivingOutput

public boolean isDrivingOutput()

Must be implemented to state whether the cell is driving the tri-state output, based on the enable input.

Returns:

true if the driver is presently driving the output.
