Block Design Pinning Doesn't Lock Down Placement

Jump to solution

Hello, I've tried usign the "Pin" feature in the Block Design on my modules and ports to lock down the placement of things but it still changes things. What could I be doing wrong? Is there another know I need to fiddle with?

 

Thanks,

Joe

Do you see the pin symbol on the BD cells?

Share the snapshots which shows the location gets changed even after pinnning.

Pinning affects "Regenerate" and "Optimize"  features available from toolbar..

While doing other operations like adding new IPs or applying block/conneciton automation, all existing IP block locations are presevered i.e. All the blocks location are "pinned" while doing all operations except "Regenerate" and "Optimize Routing"

If you don't see pinning while doing "Regenerate" or "Optimize" , pleave provide a testcase.
