[SI-LIST] HS Ground and Power ground seperation

Hi All;
 

I've heard various pros and cons about separating High speed ground (
ground planes used as references or return current paths for high speed
digital signals)  from power grounds ( ground planes used for DC return
current paths) . What is the consensus ? Separation with ferrite beads
between the different types   joining all grounds together or   one
common ground ?

 

Thanks
