ABSTRACT:
A method and apparatus are provided for implementing automated electronic package transmission line characteristic impedance verification. A sinusoidal voltage source is coupled to a transmission line test structure for generating a selected frequency. Impedance measuring circuitry is coupled to the transmission line test structure for measuring an input impedance with an open-circuit termination and a short-circuit termination. Characteristic impedance calculation circuitry is coupled to the impedance measuring circuitry receiving the input impedance measured values for the open-circuit termination and the short-circuit termination for calculating characteristic impedance. Logic circuitry is coupled to the characteristic impedance calculation circuitry for comparing the calculated characteristic impedance with threshold values for verifying acceptable electronic package transmission line characteristic impedance.
