Invited paper: System-wide fault management based on IEEE P1687 IJTAG

Fault tolerance and fault management mechanisms are necessary means to reduce the impact of soft errors and wear out in electronic devices. The semiconductor products manufactured with latest and emerging processes are increasingly affected by these effects. The paper describes a new general scalable fault management architecture based on the latest upcoming DFT standard IEEE P1687 IJTAG. The standard allows to create an efficient and regular network for handling fault detection information as well as to manage test and system resources as a system-wide background process during the system operation.
