ISE constraint import vivado a total of several steps

Recently, some V7 projects that friends have done in ISE need to switch to vivado. However, after importing the code, I found that vivado no longer supports UCF files. If you copy UCF constraints to VIVADO's XDC constraints, it is not only a waste of time, but also easy. Error, here is a way to switch between the two constraints.

The constraints in ISE are as long as this.

Unable to support UCF when importing

At this point, we can open ISE and open the graphical constraint interface through PlanAhead.

Right-click the export constraint to CSV format and remember the exported path.

Now you can close ISE, then import the code in vivado, then combine it.

Open the integrated design,

Open IO Planning,

Open File -> Import IO Ports

Point to the csv file exported by ISE,

You can see the pin constraints easily imported!
