Port with no output delay
WebSpecifies that the delay value should be treated as the minimum delay. Required: No ¶ Specifies the delay value to be applied Required: Yes [get_ports {}] ¶ Specifies the port names or port name regex. Required: Yes Note If neither -min nor -max are specified the delay value is applied to both. set_clock_uncertainty ¶ WebAug 22, 2014 · set_output_delay -clock clk -max 3 [get_ports {data [*]}] set_output_delay -clock clk -min 1 [get_ports {data [*]}] -add_delay This still gave me the same warning as before. Only if I applied add_delay to both: set_output_delay -clock clk -max 3 [get_ports {data [*]}] -add_delay set_output_delay -clock clk -min 1 [get_ports {data [*]}] -add_delay

WebAug 20, 2024 · Try changing the USB port. The convenient USB inputs on the front of desktop computers are notoriously laggy because they’re connected to the motherboard by flimsy little itty-bitty wires in there. USB ports soldered directly onto the mobo do a much better job of quickly handling data. WebIf you do not put a constraint (eg. set_input_delay, set_output_delay, create_clock, others) on a port then Vivado will ignore the port during timing analysis. The set_input_delay and set_output_delay constraints are typically used when connecting the FPGA to an external …
WebAccurate timing analysis requires constraining all input and output ports. Follow these steps to identify unconstrained paths and apply input and output delay constraints to the ports. To identify unconstrained path in the design, double-click Report Unconstrained Paths the Diagnostic reports. WebOct 28, 2024 · 前言I/O Delay约束主要有两个命令：set_input_delay和set_output_delay …
Webset_false_path -from * -to [get_ports { output_port }] (where output_port is a module's top level port assigned to a pin) If Time Quest gives you a diagnostics that not every output port has a delay, you may want to add some dummy delay as well, like this: set_output_delay -clock [get_clocks src_clk] 2 [get_ports { output_port }] WebFor I2O paths, the start point is input port whereas end points are output ports. One can assume input delay for input ports and output delay for output ports. Normally the combinatorial paths between inputs and output ports are constrained so that minimum and maximum delay constraints are met. Figure 8: Min/Max delay constraints for I2O paths ...
