eFPGA-Enabled Dynamic Access Control for Secure IEEE 1687 (IJTAG) Networks
Modern System on Chip (SoC) designs integrate numerous embedded instruments for testing, debugging, postsilicon validation, and in-field monitoring. The IEEE 1687 (IJTAG) standard provides scalable access through a reconfigurable scan network of Segment Insertion Bits (SIBs), but this flexibility exposes internal resou...
