WebJan 24, 2008 · The data and clock should be synchronous (edge aligned) as seen from the output port of the FPGA and not as seen from the different input ports. It also does not matter if there is a delay inside the FPGA, as long as the output data and clock are alligned. For the generated clocks do I need to specify the output of the clock multiplexer as the ... WebIf the clock is internal the duty cycle is irrelevant (unless you are also using the falling edge). If the clock is only going out of the FPGA, then you don't need a "true" clock on a clock network, and the periodic signal can be generated at the IOB (using an IOB flip-flop or ODDR). ... A generated clock is a clock that derives most of it's ...

WebI want to detect the edges on the serial data signal (din). I have written the following code in VHDL which is running successfully but the edges are detected with one clock period delay i.e change output is generated with one clk_50mhz period delay at each edge. Could anyone please help me to detect edges without delay. Thank you. WebIf it is correct and the master clock does not have a timing path to the generated clock, define the generated clock as a primary clock by using create_clock.
