Patent ID: 7157926

Claim:
A universal Padset on a substrate for the de-embedding of pad and signal line parasitics, comprising: an input pad group including at least a first input signal pad and a first ground pad; an output pad group including at least a first output signal pad and a second ground pad; a first input-signal-routing network having a layout configuration for routing said first input signal pad to a first input node layout location of a first predetermined test device as determined from the layout configuration of said first predetermined test device; a first output-signal-routing network having a layout configuration for routing said first output signal pad to a first output node layout location of said first predetermined test device as determined from the layout configuration of said first predetermined test device; a second input-signal-routing network having a layout configuration for routing said first input signal pad to a second input node layout location of a second predetermined test device as determined from the layout configuration of said second predetermined test device; and a second output-signal-routing network having a layout configuration for routing said first output signal pad to a second output node layout location of said second predetermined test device as determined from the layout configuration of said second predetermined test device; wherein the layout configuration of said first test device is different from the layout configuration of said second test device.
