Connecting power rings to respective power pads

Hello,
I am using Synopsys tools for P&R. Have completed hard macro placement, I/O pad placement, power ring creation and power strap creation on Jupiter XT and/or Astro. Would like to know how to connect the VCC and GND I/O pads to the respective power rings?

Thanks in advance
chetan

Dear Sir,

you can user this command "axgPrerouteInstances" to connect power and ground.

Hi chetanbs,

You need to run the aprPGConnect command to let the tool know what is the net name for the VCC/VSS pin of the IO pad.

Then you need to execute axgPrerouteInstances command to do the physical connection.

Below is the example. Hope this help.

aprPGConnect
setFormField "Connect/Disconnect PG" "Net Name" "VDD"
setFormField "Connect/Disconnect PG" "is 1'b1/1'b0" "1"
setToggleField "Connect/Disconnect PG" "Cell Types" "Pad" 1
setToggleField "Connect/Disconnect PG" "Net SubType" "Pad" 1
setFormField "Connect/Disconnect PG" "Port Pattern" "VDD.*"
setFormField "Connect/Disconnect PG" "Net Type" "Power"
formApply "Connect/Disconnect PG"
setFormField "Connect/Disconnect PG" "Net Name" "VSS"
setFormField "Connect/Disconnect PG" "is 1'b1/1'b0" "1"
setToggleField "Connect/Disconnect PG" "Cell Types" "Pad" 1
setToggleField "Connect/Disconnect PG" "Net SubType" "Pad" 1
setFormField "Connect/Disconnect PG" "Port Pattern" "VSS.*"
setFormField "Connect/Disconnect PG" "Net Type" "Ground"
formApply "Connect/Disconnect PG"
formCancel "Connect/Disconnect PG"

axgPrerouteInstances
setFormField "Preroute Instances" "Primary Routing Layer" "Specified"
setFormField "Preroute Instances" "Horizontal Layer" "81"
setFormField "Preroute Instances" "Vertical Layer" "126"
setFormField "Preroute Instances" "Nets" "Specified"
setFormField "Preroute Instances" "Net Name(s)" "VDD,VSS"
setFormField "Preroute Instances" "Route Pins" "Only Those on"
setFormField "Preroute Instances" "Route Pins" "All"
formApply "Preroute Instances"
formCancel "Preroute Instances"
