ABSTRACT:
Characterization and validation boards having the capability of allowing selective variation of current loading, localized heating, operational speed and signal pin assignment. Each printed circuit board includes a connector that is electrically coupled to a backplane of a bus system. The connector has power, ground and signal contacts. On a first side of each printed circuit board is a series of parallel circuits of resistors grounded at first ends and individually connected to switches at second ends. The switches allow a user to select a desired current load for each power contact and to emulate thermal characteristics of other boards. Clock circuitry is programmable to transmit or receive selectable clock frequencies. Bus interface circuitry, along with shorting jumpers select from a plurality of signal outputs to programmable signal contacts of the connector.
