IDDQ Testing of Bridging Faults in Logic Resources of Reconfigurable Field Programmable Gate Arrays
This paper presents an IDDQ-based test strategy for detecting bridging faults in the logic resources of reprogrammable Field Programmable Gate Arrays (FPGAs). The proposed approach utilizes the programmability of the Configurable Logic Blocks (CLBs) to achieve 100 percent coverage of IDDQ-testable bridging faults. We use a hieararchical approach for generating tests and configurations. At the c...
متن کاملImplementation of Restartable BIST Controller for Fault Detection in CLB of FPGA
Today Field Programmable Gate Arrays (FPGAs) are widely used in many applications. Complicated integrated circuit chips like FPGAs are prone to different types of Faults due to environmental conditions or aging of the device. The rate of occurrence of permanent faults increases with emerging technologies because of increased density and reduced feature size, and hence there is a need for period...
متن کاملEmbedded Processor Based Fault Injection and SEU Emulation for FPGAs
Two embedded processor based fault injection case studies are presented which are applicable to Field Programmable Gate Arrays (FPGAs) and FPGA cores in configurable System-on-Chip (SoC) implementations. The case studies include embedded hard core and soft core processors which manipulate configuration memory bits to emulate physical and transient faults in the FPGA core including shorts and op...
متن کاملApplication-Dependent Diagnosis of FPGAs
A new technique for diagnosis of faults in the interconnects and logic blocks of an arbitrary design implemented on an FPGA is presented. This work is complementary to application-dependent detection methods for FPGAs. This technique can uniquely identify any single bridging, open, or stuck-at fault in the interconnect as well as any single functional fault in the logic blocks. The number of te...
متن کاملEstablishment of Secured Communication
The main objective of this project is handling the large numbers of faults in F.P.G.A. configurable logic blocks. A key novel feature is the reuse of defective logic blocks to increase the number of effective spares and extend the mission life. To increase fault tolerance, we not only use nonfaulty parts of defective or partially faulty logic blocks, but we also use faulty parts of defective lo...
