Abstract
This paper presents the design, layout, and successful simulation of a configurable logic block (CLB) for a field-programmable gate array (FPGA) architecture based on a next-generation technology, quantum-dot cellular automata (QCA). Previous work on QCA-based FPGAs has focused on programmable interconnect. In contrast, this paper focuses on programmable logic. A novel single-layer CLB with fixed interconnect is developed by implementing four look-up tables (LUTs). Also, this paper presents a novel serial write/random-access read QCA memory design, which is one of the components in a LUT QCADesigner software is used to design and simulate a 4-to-16 decoder, 16-bit memory, and output circuit to implement a LUT. The simulation of the CLB confirms the expected outcomes
