The two views of the processor (pictures 1&2) show the block view and instance view, the schematic sheet banner is italic when you are looking at the instance view. The instance view shows the state of the design within the full design context (where it is instantiated and when you have opened it from within the design). If you look at the information on the Reference Designator property you should see that R126 is the instance value and overrides the block value of R78. The other R78 is the instance value on the NVSRAM sheet. It is these instance values you will see in layout. The 'Find' command will search for all values, schematic, block and instance which is why you have multiple hits.
Thanks for your reply sir,
So this is usual one, no need to get confuse?
Will all reusable block have instance view sheets after re-numbering? Don't we need to consider this? What is the use of that?
I have some recent experience with L-P reuse blocks so I'll chime in here. This is usual, when a reuse block instance is placed on a schematic, it's child schematic sheets are type sheet instance. Therefore the block values are ignored and the system uses instance values. In your case there would be no Ref Des conflicts since package and layout will use instance values R78 and R126.
If you haven't yet, I would suggest reading the DxDesigner properties reference and look up RefDes Suffix, Refdes Prefix, etc. I see you have Reuse Cell Ref Des on there. Did you make the assignments I see for that property? Remove the instance value. It's used by the packager and layout for internal housekeeping.
I'm not saying I'm an expert, I just know what's worked for me.
Thank you sir,
Now i understood.
Glad to hear this has been resolved, will you be so kind as to mark this question as answered so that others will benefit from the information.
