VPSS axis frequency

Jump to solution

I was able to get the project with this core up and running with 100MHz aclk_axis. Now I need to speed it up a bit (to 110MHz) and I've ran into the problem that the pin property on the IP block is still 100Mhz hence the synthesis is failng due to frequencies mismatch. Reset\regenerate output products doesn't help. Other IP blocks pick up the correct frequency.
Is there any frequency dependencies that I've overlooked? Or is there any workaround?

Video Processing Subsystem v2.0, Vivado 2018.3, Kintex Ultrascale+.

UPD: Ah, I see. The default value of aclk_axis is 300MHz, in the example design - 200MHz.

Ah, I've found the solution.
It was just a bug in Vivado. Deleting the IP block in the block design and putting in a new one make the pin to hookup the new frequency correctly.
