01 Structure of SIB SIB (Segment Insertion Bit) is a fundamental unit of the IEEE 1687 standard specification. Utilizing the characteristics of SIB circuitry, we can achieve plug-and-play and flexible configuration of the IJTAG network. Essentially, SIB is a single-bit TDR. By controlling the two states of SIB being on and off, we can connect … Read more
As chips become larger, the number of IPs integrated on SOC, whether hard IP or soft IP, is increasing. The testing of these IPs is crucial for the entire chip, which is why the IEEE 1687 protocol has emerged. I believe that the 1687 protocol is an upgrade to 1149.1 and 1500. Compared to them, … Read more
Huang Xin, Song Boyuan, Guo Xiaomin, Lin Jieqin (Guilin University of Electronic Technology, School of Electronic Engineering and Automation, Guilin, Guangxi 541000) Abstract: In order to utilize the traditional JTAG interface for testing and controlling a large number of specific IP testing instruments within the SOC, a universal and portable single-layer network testing method based … Read more
