Embodiment Construction
[0029] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0030] like figure 2 As shown, an embedded SRAM memory test structure based on IEEE 1500, including a BIST test controller and an embedded SRAM packaged test shell based on IEEE 1500 standards, the test shell receives control signals and command signals sent by the BIST test controller , test address data, test stimulus data, and test response The data is output to the BIST test controller, and the test shell Wrapper surrounds the tested embedded SRAM. The components in the test shell conform to the functional description of the IEEE 1500 standard; the BIST test controller has a clock signal, a state mode control signal port, and a test controller The control signal output port of the test shell Wrapper is connected to the corresponding port of the test shell; the data output port WSO of the test shell is conn...
