Recently, I got a case where i need to select all Via08. i wanna go through dbGet for it.
Here is what i tried,
dbGet top.nets.sVias.via.name VIAGEN89_1 gives me all VIAGEN89_1 list. I used -p optiuon to get the db pointers .
dbGet top.nets.sVias.via.name VIAGEN89_1 -p is giving me db Pointers but all the pointers are looking same, that means
dbGet -u top.nets.sVias.via.name VIAGEN89_1 is giving one pointer.
Why is it giving like this ? and dbSelectObj [dbGet top.nets.sVias.via.name VIAGEN89_1 -p] is not selecting the via, why?
I tried for the insts , though it is giving the pointers correct but not selecting with dbSelectObj.
can some one help me. I wanna learn more about the dbGet.
It looks like you're on the right track, but I think you need to do a "-p2" instead of "-p" because you want the pointer to the via instantiation rather than the via master.
Here's a blog post on selecting by pointer:/blogs/di/archive/2009/12/16/selecting-pointers-with-dbget-and-dbselectobj.aspx

And here's a presentation I use to get users started with dbGet (Cadence.com login required): http://support.cadence.com/wps/mypoc/cos?uri=deeplinkmin:DocumentViewer;src=wp;q=Training/Digital_IC_Design/dbGet.pdf
Hope this helps,Bob
