instance renaming

Rajesh Vembu

How do we rename instances in encounter? I'm aware of changeInstName command, but it does not change the hierarchical name.

 

For example, if i have to change an instance name from a/b/c to x/y/z, how to accomplish it?

    ### usage: rename_FEhcells  a/b/c  a1/b1/c1 

    proc rename_FEhcells { oldhcell newhcell } {

    set ptr_oldhcell [dbGetHInstByName $oldhcell]
    set ptr_newhcell [dbGetHInstByName $newhcell]
    set i 0
    dbForEachHInstTreeInst $ptr_oldhcell instptr {
     set oldHinst [dbInstName $instptr]
     set oldhcells_rootpath_length [expr [string length $oldhcell] + 1]
     #set last_name [dbInstBaseName $instptr]
     set last_name [string range $oldHinst $oldhcells_rootpath_length end]

     set cellName [dbInstCellName $instptr]
     set instLoc [dbInstLoc $instptr]
     set x [dbDBUToMicrons [lindex $instLoc 0] ]
     set y [dbDBUToMicrons [lindex $instLoc 1] ]

     set R [string range [dbInstOrient $instptr] 3 end]

     deleteInst  $oldHinst
     addInst -cell $cellName -inst $newhcell/$last_name -loc $x $y -ori $R   -physical

    incr i

                                                  }
    puts "#######################################################"
    puts "Total $i Hinsts changed Hierarchy for ECO in Encounter!"
    puts "#######################################################"
    }

    Are you sure with this solution? It will only construct a DUMMY hier instance with not right connections. Please think harder when you want to propose an answer.
