WebThis analysis starts in "Data Arrival Path" with setting the input port (test_in) at 2 ns, as specified in the min input delay constraint, and continues that data path. Together with the FPGA’s own data path delay (3.057 ns), the total data path delay stands at 5.057 ns. The clock path is then calculated in "Data Required Path", starting from ... Webset_input_delay -clock clk -min 2 [all_inputs]The Synopsys® Design Constraints (SDC) format provides a simple and easy method to constrain the simplest to the most complex designs. The following example provides the simplest SDC file content that constrains all clock (ports and pins), input I/O paths, and output I/O paths for a design.

WebAs with the calculation for set_output_delay -max, the data path continues the clock path until the output is stable. This is calculated to happen at 3.826 ns (note the difference with the slow model). This is compared with the time of … WebInput Delay Constraints You can use a maximum skew specification to calculate input delay values. The maximum skew specification indicates the allowable time variation for individual bits of a data bus to arrive at the FPGA. The value of the input maximum delay is maximum skew value. The value of the input minimum delay is -maximum skew value.
