What is delay in FPGA?
By default, LabVIEW FPGA places a register between logic functions on the block diagram to maximize the propagation time available for each operation to execute. Propagation delay is the time it takes a signal to travel from one register to the next.
How do you set output delay?
You access this dialog box by clicking Constraints > Set Output Delay in the TimeQuest Timing Analyzer, or with the set_output_delay Synopsys® Design Constraints (SDC) command. Specifies the required data arrival times at the specified output ports relative to the clock ( -clock ).
What is FPGA timing?
Timing is a term used in digital circuits to refer to the time it takes a signal to propagate from one flip-flop, through some combinational logic, to the next flip-flop.
How is clock implemented in FPGA?
PLL in FPGA
Instead of getting a dedicated clock for everything, you can simply take a clock that has, for example, a wave frequency of 50 MHz, and then have it pulse every so often per number of cycles to get a customized clock with variable frequencies.
