synthesis out-of-date message right after the synthesis and implementation

Jump to solution

Hello,

I have Vivado 2018.3. When I try to generate Bitstream immediately after running synthesis and implementation I see the following message:    

*********

Synthesis is out-of-date. OK to launch synthesis and implementation first? 'Generate
Bitstream' will automatically start when synthesis and implementation completes

*************

So, the synthesis and implementation are running again including the scripts set in tcl.pre. which is bad. Why can Vivado see what it did just seconds before? I did not touch any file of the project.

Thank you.

tcl.pre touches only revision text file, which I thought should not be checked by synthesis. I will try to disable tcl.pre and see the difference, if any.

Thank you.

Does your tcl.pre touch any files?  Synthesis checks file dates before running tcl.pre.  If any file is touched, synthesis is out of date before it even finishes.
