  • Boundary scan register for differential chip core
    Patent number: 6990618
    Abstract: An integrated circuit including a first cell configured to perform boundary scan testing, and an I/O node coupled to the first cell, wherein the I/O node is configured to carry a first differential signal. A level translator may be coupled between the I/O node and the first cell, wherein the level translator is configured to translate the first differential signal into a single ended signal. A level translator may be coupled between the I/O node and the first cell, wherein the level translator is configured to translate a single ended signal into the first differential signal. Core logic may be coupled to the first cell, wherein the core logic is configured to process a second differential signal, and a level translator may be coupled between the core logic and the first cell, wherein the level translator is configured to translate the second differential signal into a single ended signal.
