2012.3 Vivado - Pressing 'Run Synthesis' in "Synthesis is Out-of-date" dialog box does not run synthesis


After upgrading an IP core, Vivado reports that Synthesis is Out-of-date. 

Then, if  the synthesized design is opened, A dialog box is displayed saying that the Synthesis is Out-of-date. This is expected behavior.

However, if  the Run Synthesis button is clicked in the Synthesis is Out-of-date dialog box, Vivado opens the out-of-date design instead of running synthesis.


This is a known issue in the 2012.3 release.

Synthesis can be run by using the Synthesis button outside of the dialog box.

This issue is fixed in Vivado release 2012.4.
