How to dump out blockages into a file

You can write them out in a DEF file:

defOutBySection -noComps -noNets -pBlockages -rBlockages myBlockages.def

pBlockages is the placement blockages (all kinds) and rBlockages is the routing blockages. 

HI Kari,

Thanks for the Command

But Partial Blockages are not being dumped ,I tried even loading the DEF file but the partial blockage are no where seen

This is a tcl command-based solution for dumping out the placement (including soft, partial & hard) /routing blockages from Encounter session:

################################################################################
# Procedure to save blockages into tcl command
# Usage: saveBlockages -type <placement | routing | all> -outFile <output_tcl_file>
################################################################################
proc saveBlockages {args} {

    global env

    # Get blockage type
    if {[regexp {\-type} $args]} {
 set blockageType [lindex $args [expr [lsearch $args -type] + 1]]
    }

    # Get output file
    if {[regexp {\-outFile} $args]} {
 set outfile [lindex $args [expr [lsearch $args -outFile] + 1]]
    }

    # Help
    set helpString "Usage : saveBlockages \
                                \-type <placement | routing | all> \
                                \-outFile <file_name> \
                                \-help"

    if {[regexp {\-help} $args] || $args == ""} {
        puts $helpString
        return 0
    }

    # Main code

    set f [open $outfile w]

    # Placement blockages
    if {$blockageType == "placement" || $blockageType == "all"} {

 foreach pblkgType [dbGet -u top.fPlan.pBlkgs.type] {

     foreach obsPtr [dbGet -p top.fPlan.pBlkgs.type $pblkgType] {
  set obsName [dbGet $obsPtr.name]
  set box [exl [dbGet $obsPtr.boxes]]
  
  switch -- $pblkgType {

      "hard" {
   puts $f "createObstruct -box $box -name $obsName"
      }
      "partial" {
   set density [dbGet $obsPtr.density]
   puts $f "createDensityArea -name $obsName $box $density"
      }
      "soft" {
   set density [dbGet $obsPtr.density]
   puts $f "createDensityArea -name $obsName $box $density"
      }
  }
     }
 }

    }

    # Routing blockages
    if {$blockageType == "routing" || $blockageType == "all"} {
 
 foreach rBlkPtr [dbGet top.fPlan.rBlkgs] {
     set name [dbGet ${rBlkPtr}.name]
     set attr [dbGet ${rBlkPtr}.attr]
     set layer [dbGet ${rBlkPtr}.layer.name]
     foreach box [exl [dbGet ${rBlkPtr}.boxes]] {
  puts $f "createRouteBlk -box ${box} -layer ${layer} -name ${name}"
  
     }
 }
    }
   
    close $f
}
