Field-programmable gate arrays (FPGAs) are used in a variety of markets that have differing cost, performance and power consumption requirements. While it would be ideal to serve all these markets with a single FPGA family, the diversity in the needs of these markets means that generally more than one family is appropriate. Consequently, FPGA vendors have moved to provide a diverse set of families...
Field Programmable Gate Arrays (FPGAs) are increasingly being used to implement large datapath-oriented applications that are designed to process multiple-bit wide data. Studies have shown that the regularity of these multi-bit signals can be effectively exploited to reduce the implementation area of datapath circuits on FPGAs that employ the traditional bidirectional routing. Most of modern FPGAs,...
In component-based system design, systems are composed by integrating fully physically implemented hard-IP cores. This design style has the potential to close the design productivity gap that will arise when FPGAs will head over the one million look-up table boundary by minimizing, or even fully removing, costly verification and place&route steps during the system integration phase. This integration...
The cluster-based FPGA can significantly improve timing and routability. Packing is introduced in the CAD flow to pack logic elements into clusters. In order to reduce unnecessary connectivity within a cluster, sparse crossbar FPGA architectures are under investigation. This paper proposes a novel packing algorithm using direct graph searching method and connection gain function. Experimental results...
Due to their reconfigurability and their high density of resources, SRAM-based FPGAs are more and more used in embedded systems. For some applications (Pay-TV,Banking, Telecommunication ...), a high level of security is needed. FPGAs are intrinsically sensitive to ionizing effects, such as light stimulation, and attackers can try to exploit faults injected in the downloaded configuration. Previous...
In this paper, we present a novel technique for online testing of feedback bridging faults in the interconnects of the cluster based FPGA. The detection circuit will be implemented using BISTER configuration. We have configured the Block Under Test (BUT) with a pseudo-delay independent asynchronous element. Since we have exploited the concept of asynchronous element known as Muller-C element in order...
