Structures, architectures, systems, an integrated circuit, methods and software for configuring an integrated circuit for multiple packaging types and/or selecting a packaging type for an integrated circuit. A structure generally includes a bump pad having a plurality of electrically disconnected bump pad sections, a plurality of bond pads each configured for electrical connection to one of the bump pad sections, and a plurality of conductive traces, each adapted to electrically connect one of the bond pads to the one bump pad section. A method generally includes the steps of forming the bump pad, the bond pads, and the conductive traces from an uppermost metal layer, and forming an insulation layer thereover. Another method generally includes forming the uppermost metal layer, and forming either a wire bond to at least one of the bond pads, or a ball bond or solder ball to electrically connect the bump pad section.

A system including a component of a transceiver, a comparator, a counter, and a calibration circuit. The component receives an input signal comprising packets and based on the input signal, generates output signals to transmit the packets. The comparator compares the output signals to generate a comparison signal. The counter counts cycles of a clock signal to provide a count value. The control device, based on the comparison signal, transitions the counter between incrementing the count value and decrementing the count value. The calibration circuit operates in first and second calibration modes; during the first calibration mode, calibrates the component until the counter transitions a predetermined number of times between incrementing the count value and decrementing the count value; and during the second calibration mode, calibrates the component until (i) the counter transitions between incrementing and decrementing the count value, or (ii) counts a predetermined number of cycles.

A calibration signal generator generates calibration signals based on the performance parameter and outputs the calibration signals to the transceiver component. A comparator receives the outputs of the transceiver component and generates a difference signal. A calibration adjustment circuit communicates with the calibration signal generator and the comparator and adjusts the performance parameter to reduce the difference signal. Alternately, a reference signal generator generates a reference signal. A comparator receives the reference signal and a second signal from the transceiver component and generates a difference signal. A calibration adjustment circuit adjusts the performance parameter of the transceiver to reduce the difference signal.
