Title:
CONTROLLABLE CHIPLET SERIAL TEST CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/212998
Kind Code:
A1
Abstract:
A controllable chiplet serial test circuit, relating to the technical field of testing or measurement of semiconductor devices in the manufacturing or processing process. The test circuit comprises a master test module, a slave test module, a clock control module and an output module, the master test module consisting of a test access port module, a segment insertion bit module and a test data register module; a test control signal generated by the master test module is received by the slave test module, and then respectively controls test input signals of a slave chiplet. In addition, the test control signal is input to the clock control module to obtain a clock signal of the slave chiplet. An output signal of the test output module is determined by the test control signal. The test circuit directly controls an internal test signal of a multi-chiplet integrated circuit using an external test port, realizing selection of a chiplet test and final test output, and ensuring the effectiveness and independence of each chiplet test.
