to delete all the io pins in a design and load a new io file

Hi Sar

I assume you want to unplace the existing pins and load a new IO file. If that's the thing you are after, you can try the following procedure:

################################################################################
# Procedure to unplace IO pads/pins
# Usage: unplaceIOs {-pads | -pins}
################################################################################
proc unplaceIOs {args} {

unlogCommand dbGet

# Select IO pads/pins
if {[regexp {\-pads} $args]} {

dbSet [dbGet -p top.fPlan.ios.inst.cell {.baseClass == "pad"}].pstatus unplaced

} elseif {[regexp {\-pins} $args]} {

# Unplace pins
dbSet top.terms.pStatus unplaced

# Delete associated metals as well
deselectAll

foreach pinPtr [dbGet -p top.terms.isSpecial 0] {

# Unplace pins
dbSet ${pinPtr}.pStatus unplaced

# Get metal layer info
set layer [regsub {[A-Za-z]} [dbGet $pinPtr.layer.name] {}]

# Get box info
set box [dbGet ${pinPtr}.pins.allShapes.shapes.rect]

if {$box != 0x0} {
set x1 [lindex $box 0]
set y1 [lindex $box 1]
set x2 [lindex $box 2]
set y2 [lindex $box 3]

eval selectPhyPin $x1 $y1 $x2 $y2 $layer [dbGet ${pinPtr}.name]
}
}

# Delete selected pads/pins
deleteSelectedFromFPlan
deselectAll
}

redraw
}

Thanks
