Abstract

See full text

A method and apparatus for applying a test signal to a node of a signal path of an integrated circuit using a parasitic capacitance of the integrated circuit associated with the node. For example, a parasitic capacitance associated with a bond pad may be used to apply a test signal to a signal path. Alternatively, a parasitic capacitance associated with a shielding element may be used to apply a test signal to the signal path.
