2014.4 Vivado Power - Vectorless switching activity propagation is incorrect for DSP blocks


If I run vectorless power analysis, the switching activity propagation is incorrect for the DSP blocks.

I am running the 'report_switching_acitivity' command with mixed results, after setting the 'set_switching_activity' command on the input ports.

How can I work around this?


The workaround is to place the 'set_switching_activity' command on the output nets of the DSP component.

This issue is scheduled to be fixed in the next release of the tools.
