WebMulticycle paths are data paths between two registers that operate at a sample rate slower than the FPGA clock rate and therefore take multiple clock cycles to complete their execution. To synchronize the clock rate to the sample rates of various paths in your design, you can use a single clock mode or a multiple clock mode. Web// Documentation Portal .
