After the timing and physical constraints have been imported, independent of the number of source files or whether the design is in Project or Non-Project mode, all the constraints can be exported as a single file with the write_xdc command. The constraints are written to the specified output...
• Step 3: synthesizes the design on the specified target device. This step compiles the HDL design files, applies the timing constraints located in the XDC file, and maps the logic onto Xilinx primitives to create a design database in memory. The in-memory design resides in the Vivado ...
In many cases, when your constraints set contains several XDC files, the target constraint file is not the last file in the list, and will not be loaded last when opening or reloading your design. As a consequence, the constraints sequence saved on disk can be different from the one you ...
set outputDir ./Tutorial_Created_Data/cpu_output In the preceding example, the first word is the Tcl set command, which is used to assign variables. The second and third words are passed to the set command as the variable name (outputDir), and the variable value (./Tutorial_Created_Data...

- anything unspecified by code is leaving the door open for the synthesis machine to do what it wants so it may do erratic things in unspecified areas because they are not specified. - another possible source for erratic signals is timing and a good way to check is to see if the behavi...
Now, before we can configure Qt5 we must create 'mkspecs' for our Xilinx Zynq. So, create new device folder 'linux-arm-xilinx-zynq-g++' and two files in it. 'qplatformdefs' contains just an include, but second file 'qmake.conf' is quite important. This is the place where we set ...
