Hi Willibi, Just came across your post regarding the use of POWER_GROUP property on blocks in the top-level design. (dated 7/17/3) I have tried the same in PSD 14.2, but have not found any difference from the old behavior. The \PARAMETER solution works, but so does the old methodology. (Since POWER_GROUP property is specified as inherit(cell) in the cdsprop.paf file, it is automatically passed on to all instances in the block, to which it is attached.) Could you please elaborate your scenario? Regards, Abha
