After opt_design, the clock '[get_clocks -of [get_pins pin2]' becomes asynchronous to all of the clocks of the design and the sign-off timing results are invalid. There is a check that when set_clock_groups is applied, if there is only a single -group remaining after the other group...
In this document you will see some examples of Tcl commands and Tcl scripts, and the results that are returned by theVivado Design Suite when these commands are run. The commands and their return values appear with the following formats: • Tcl commands and example scripts: puts $outputDir...
Unlike Tcl scripts, XDC files are managed by the Vivado IDE so that any constraint edited through the graphical interface or the Timing Constraints Editor can be saved back to its original XDC file. For this reason, only XDC commands can be used in a XDC file. If you need to use other...

Synthesis turns HDL files into a transistor level description based on timing and I/O constraints. To run Synthesis click either in the toolbar or in the Flow Navigator. The output of Synthesis is then passed to Implementation. Implementation has several steps. The steps that are always run ...
approximations. By leveraging a combination of architectural knowledge, repeating patterns, and extensive analysis of Vivado timing reports, we obtain a slightly pessimistic, lumped delay model within 2% average accuracy of Vivado for UltraScale+ devices. Compared to Vivado, RWRoute results in a 4.9...
When any of these file groups are empty, the final Review and Package page issues a warning about missing file. IMPORTANT: The Vivado IP packager does not support IP in the Core Container format. Disable the Core Container feature for all IP prior to packaging. For more information on Core...
Because the Vivado tools are timing driven, it is important to fully constrain a design, but not over-constrain, or under-constrain it. Over-constraining a design can lead to long compile times and sub-optimal results because the tool can struggle with unrealistic design objectives. Under- ...
