59799 - Vivado Constraints - How to avoid overwriting clock constraints when using create_clock constraints in scoped constraint files? Description When using "create_clock -name" constraints in scoped constraint files (SCOPED_TO_REF, SCOPED_TO_CELLS), the following warning can be observed when ope...
In Vivado all clocks are related by default, so even though I define two clocks, they are effectively the same if they have the same attributes create_clock -name fpga_clk -period 10 [get_ports fpga_clk_pin] create_clock -name virt_clk -period 10 Now I am going to define the ...

This can be done in the Vivado I/O Pin Planning GUI. The clock constraint needs to be added to the XDC file, for example: create_clock -add -name clkin1_p -period 5.833 [get_ports clkin1_p] The other constraints in the Xapp585 UCF file that need to be ported to the XDC file...
In the sources window, right-click and choose “Edit Constraints Sets…”. Click “Create File” and name it as “styx_sq_wave.xdc”. Then, click OK to let Vivado create the constraint file. In this file, we will add location constraint for `sq_wave` output port which we had created...
Yes, the reason I'm swapping pins is because I traced them. I don't think you can just swap pins in the constraint file. (but If I'm wrong I would like to know since that would make life easy!) It is my experience (and understanding) that Vivado will complain when generating...
• Use persistent variables to create unit and variable integer design delays in MATLAB Function blocks inside the frame-to-sample DUT subsystem. • Use the Delay size threshold for external memory (bits) model configuration parameter to map design delays to external memory. The parameter can ...
First you may remove set_false_path and ignore any reported violations or set to some high multicycle. second, this is an altera example that involves data path only: # Create a max skew constraint that includes only data path arrival set_max_skew -from [get_keepers inst...
In some cases: authentication is not only important — it is vital. Let us consider Federal Tax: Forms 1040. We must all file our tax forms, every year, under penalty of law. Unfortunately we have some crooks around who like to
