PROCESSOR AND CHIPSET CONTINUITY TESTING OF PACKAGE INTERCONNECT FOR FUNCTIONAL SAFETY APPLICATIONS

摘要

Methods and apparatus relating to processor and chipset continuity testing of package interconnect for functional safety applications are described. In an embodiment, voltage divider logic circuitry divides a reference voltage. Controller logic circuitry compares a divided voltage value from a node of the voltage divider logic circuitry and a threshold voltage value. A first end of the voltage divider logic circuitry is coupled to receive the reference voltage and a second end of the voltage divider logic circuitry is coupled to a Non-Critical-To-Function (NCTF) solder ball. The controller logic circuitry generates an error signal in response to a mismatch between the divided voltage value and the threshold voltage value. Other embodiments are also disclosed and claimed.
