چکیده
Every user of programmable logic at some point faces the question: “How large a device will I require to fit my design?” In an effort to provide guidance to their users, Field Programmable Gate Array (FPGA) manufacturers, including Xilinx, describe the capacity of FPGA devices in terms of “gate counts.” “Gate counting” involves measuring logic capacity in terms of the number of 2-input NAND gates that would be required to implement the same number and type of logic functions. The resulting capacity estimates allow users to compare the relative capacity of different Xilinx FPGA devices.

متن کاملEfficient Delay Characterization Method to Obtain the Output Waveform of Logic Gates Considering Glitches
Accurate delay calculation of circuit gates is very important in timing analysis of digital circuits. Waveform shapes on the input ports of logic gates should be considered, in the characterization phase of delay calculation, to obtain accurate gate delay values. Glitches and their temporal effect on circuit gate delays should be taken into account for this purpose. However, the explosive numbe...
متن کاملA Design Methodology for Reliable MRF-Based Logic Gates
Probabilistic-based methods have been used for designing noise tolerant circuits recently. In these methods, however, there is not any reliability mechanism that is essential for nanometer digital VLSI circuits. In this paper, we propose a novel method for designing reliable probabilistic-based logic gates. The advantage of the proposed method in comparison with previous probabilistic-based met...

The Markov random field (MRF) theory has been accepted as a highly effective framework for designing noise-tolerant nanometer digital VLSI circuits. In MRF-based design, proper feedback lines are used to control noise and keep the circuits in their valid states. However, this methodology has encountered two major problems that have limited the application of highly noise immune MRF-based circui...
