WebJul 30, 2024 · The Single-Bit Flip-Flop and Multi-Bit Flip-Flops are successfully experimented using Xilinx ISE 14.5 Simulator. The various tap size of FIR filter are designed using both SBFF and MBFF and simulated using Verilog HDL. The proposed architecture is implemented using FPGA of family Virtex-5 (XC5VLX110T-FF136). WebJan 10, 2024 · Scan chains are the elements in scan-based designs that are used to shift-in and shift-out test data. A scan chain is formed by a number of flops connected back to back in a chain with the output of one flop connected to another. The input of first flop is connected to the input pin of the chip (called scan-in) from where scan data is fed.
