set cellcnt 0

                puts stdout "inst name: $instName"                              
                puts $f "inst name: $instName"                                 
                incr instcnt                                                   
        }                                                                       
        incr cellcnt                                                            
}                                                                              
puts stdout "cell num:  $cellcnt"                                               
puts stdout "inst num:  $instcnt"

when I ran this script , error occured as shown :
**DIAG[rdaTclDbCmd.c:2977:dbiForEachCellInstCmd]: Assert "!dbmIsInstVInst(dbmCellInstList((dbsCell *)p))"
Wrong pointer type: "dbcObjVInst" (should be "dbcObjInst") in "dbInstName"
Usage: dbInstName Bad return code in "dbForEachCellInst"Bad return code in "dbForEachHeadCell"

anyone can help me ?

  • Hi Dota,

    I think the script is erroring out when you're trying to loop through each instance associated with a master cell here:

    dbForEachCellInst $cellPtr instPtr {

    dbForEachCellInst is intended to be used to loop through a "head" cell rather than a leaf cell. Here's a re-written version that I think does what you're looking for:

    set instcnt 0
    set cellcnt 0
    set f [open total w]
    dbForEachHeadCell [dbgHead] cellPtr {
    incr cellcnt
    set cellName [dbCellName $cellPtr]
    puts "[dbCellName $cell]"
    puts $f "cell name: $cellName"
    }
    dbForEachCellInst [dbHeadTopCell] instPtr {
    set instName [dbInstName $instPtr]
    puts "inst name: $instName"
    puts $f "inst name: $instName"
    incr instcnt
    }
    puts "cell num: $cellcnt"
    puts "inst num: $instcnt"

    Let me know if this does what you're looking for, and if not let me know a little more about what you're trying to accomplish.

    Thanks!
    Bob
