INTERPOSER CIRCUIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18524900 titled 'INTERPOSER CIRCUIT
Simplified Explanation
The disclosure presents a new method and apparatus for enhancing interposers that connect stacked die assemblies to system substrates. This improvement involves integrating IEEE 1149.1 circuitry within interposers to simplify interconnect testing of digital and analog signal connections between the interposer and the system substrate. Additionally, the enhancement includes 1149.1 controlled circuitry for real-time monitoring of voltage supply, ground buses, and functional digital and analog input/output signals in the interposer. Furthermore, the improvement allows for selectively serially linking the 1149.1 circuitry in the interposer with the 1149.1 circuitry in the die of the stack.

Original Abstract Submitted
The disclosure describes a novel method and apparatus for improving interposers that connected stacked die assemblies to system substrates. The improvement includes the addition of IEEE 1149.1 circuitry within interposers to allow simplifying interconnect testing of digital and analog signal connections between the interposer and system substrate it is attached too. The improvement also includes the additional 1149.1 controlled circuitry that allows real time monitoring of voltage supply and ground buses in the interposer. The improvement also includes the additional of 1149.1 controlled circuitry that allows real time monitoring of functional digital and analog input and output signals in the interposer. The improvement also provides the ability to selectively serially link the 1149.1 circuitry in the interposer with 1149.1 circuitry in the die of the stack.
