FPGA architecture exploration is a topic of great interest to hardware researchers. By synthesizing many hardware descriptions with different architecture specifications, it is possible to compare the generated circuits and draw a conclusion about those specifications. In order to be confident in results obtained from this exploration, it is necessary to verify that the circuits have been compiled...
Quantum-dot Cellular Automata (QCA) is a nano-scale compute fabric being explored by the VLSI research community as the difficulties in shrinking CMOS transistors mount. The paradigm promises high device densities and power-efficiency, and has unique properties that make it an interesting candidate for programmable devices. In this work, we propose a specialized architecture for programmable devices...
The goal of this work is to model and predict timing failure rates of digital blocks in FPGAs due to delay variation. The timing failures are modelled as transient faults depending on the input vectors to the block, as opposed to conventional critical path failures. Firstly, we present transition tables derived from the truth tables of the logic gates which are apt for our purpose. Next we present...
There is a pressing need for exploring innovative reconfigurable architectures with the steady growth in the range of FPGA based applications. However, traditional FPGA architecture design methods require time consuming CAD experimentations to identify the most suitable hardware configuration for the target application. Several analytical models have been recently proposed to predict the relative...
