Abstract
An apparatus and method to compensate for variations in effective electrical impedance of a digital bus having plurality of transmission lines in a very large scale integrated circuit includes bus driver circuitry, which comprises a plurality of transistors coupled to an output node that is connected to a corresponding one of the transmission lines. Control circuitry is utilized to selectively enable/disable the transistors, thereby adjusting the driver impedance of the bus driver circuitry so as to match a state of the digital bus.
