Reported warnings are doubled

Jump to solution

After upgrading to Vivado 2018.2.1 I noticed the reported number of warnings in Synthesis (and Implementation) are doubled. In the screenshot below 2,321 warnings were generated during synthesis but 4,642 are reported in the project messages below. These duplicate warnings cannot be deleted like user-generated warnings can be and appear to be simply reported twice.

Is there a fix for this issue coming soon?

Hi @mr-read,

 

This seems like an issue of inconsistent updating of synthesis warnings. 

 

And it is already reported to the factory. - It may get fixed in next versions of Vivado.

 

Once the synthesis run completes , and then if you click on the 2321 warnings, what do you see ? Is the number get changed?

Hi @rshekhaw,


I have attached a simple project example that instantiates a fifo. After running synthesis the tool reports 104 warnings in the Synthesis window, but 208 warnings in the Messages screen. If I open the warnings in the Messages window it shows 104 warnings for Synthesis, so I'm assuming the Messages tool is counting both the total number of warnings and the number of warnings per source (i.e. OOC Module Runs, synth_1, etc.)

 

This behavior is consitent for all Messages counts (Errors, Critical Warnings, etc.)
