WebMay 31, 2024 · set_output_delay command sets output delay requirements on an output port with respect to the clock edge. Output ports are assumed to have zero output delay if it is not specified. Example: set_output_delay 1.7 -clock [get_clocks CLK1] [all_outputs] WebJul 22, 2024 · if you are looking for set_input_delay & set_output_delay, then here is the answer: set_input_delay is sets input path delays on input ports relative to a clock edge. meaning, if you have clock period = 10 input delay = 3 Thus, your data will be arrived after 3. Same thing happen when you set "set_output_delay"

WebNov 4, 2016 · set_output_delay -max tSU set_outpt_delay -min -tH ( minus tH) This applies when clock and data go together with same delay what might confuse here is that for set_input_delay we give offset relative to launch edge for set_ouput_delay we give … Web“input_delay” represents the delay of external logic at the input. For the setup case, this is the period minus the setup time. For the hold case, this is the hold time itself. So, the min delay is Th, and the max delay is (period – Tsu): # Set the input delays set_input_delay 1.0 -min -clock clk1x [get_ports din]

WebA slow slew rate reduces system noise, but adds a nominal output delay to rising and falling edges. The lower the voltage standard (for example, 1.8-V LVTTL) the larger the output delay when slow slew is enabled. ... The slew-rate control affects both the rising and falling edges. Open-Drain Output MAX II devices provide an optional open-drain ... WebOct 10, 2010 · The set_output_delay -max 4.0 states that the external max delay is 4ns. On a simple level, that means the FPGA needs to get it's data out within 6ns so that, after the external 4ns delay is added, it can be captured by the latch edge at time 10ns. Now, where does that 4ns come from?

WebMar 28, 2016 · Some constraints like set_input_delay and set_output_delay has standard value or generalized value like, INPUT_DELAY_MARGIN is 60% of your clock period and OUTPUT_DELAY_MARGIN is 40% of your clock period. Set that value to parameter and then given to the set_input_delay and set_output_delay constraints.
