WebClock domain crossing (CDC) means facilitating data transfer from logic governed by one clock net in the FPGA to logic in another clock net. The two clocks may be skewed or have different frequencies, complicating timing closure. When one clock is faster than the other, steps must be taken to avoid data loss when transferring to the slower ... WebMany FPGAs use a phase-locked loop (PLL) to increase the internal clock speed.

WebIn a test bench, to generate the orriginal clock you do something like, process begin clk <= '0'; wait for 5 ns; clk <= '1'; wait for 5 ns; end process; this toggles the output 'clk' every 5 ns, giving a 10 ns period, i.e. 100 MHz. Please remeber this is only in a test bench, this can NOT be synthesised to go into the FPGA. Thanks.

WebThe clock will have one sole initial driver to the whole FPGA, so all destinations should receive the same edge. This would be an issue if the "same" clock is coming on several pins. Clock drivers in the FPGA have protection to start with a clean output edge, but there's always the option of waiting for an MMCM or PLL to lock before releasing ...
