Title:
CHIPLET TEST CIRCUIT BASED ON FLEXIBLE CONFIGURABLE MODULES
Document Type and Number:
WIPO Patent Application WO/2023/231276
Kind Code:
A1
Abstract:
The present invention relates to the field of very-large-scale integrated circuit testability design. Disclosed is a chiplet test circuit based on flexible configurable modules (FCMs). A circuit core structure is located in an intermediate layer. The chiplet test circuit comprises FCMs, a control signal configuration module and a test state control module, wherein the FCMs use a two-way diagonally symmetrical structure, so as to realize data transmission in a horizontal and a vertical direction; the control signal configuration module is connected to control signals of all the FCMs, and controls data transmission directions and connection and disconnection states of all the FCMs; and the test state control module controls the FCMs and shift and update operations of internal data of the control signal configuration module. The present invention can satisfy the test requirements of a chiplet in various scenarios, an original DFT test logic is reused, and a plug-and-play policy for the chiplet is satisfied, thereby improving the flexibility and controllability of a test.
