====== Create Ploc File From DEF File ======

===== Ploc File Format =====

Following is the syntax for a standard *.ploc file with no package model: 
<code>
<die_pad_name> <X-coord> <Y-coord> <layer> <POWER | GROUND>
</code>
If you want to include a package subcircuit model, then the syntax of the .ploc file should be modified as follows: 

<code>
<die_pad_name> <X-coord_um> <Y-coord_um> <layer>  
    <power/ground_domain_name> <Spice_pkg_port_name>
</code>

where the power/ground domain name is the name specified in the VDD_NETS GSR keyword, and none of the ports can be named “0’. Signal ports in the package subcircuit can be floating. Multiple pads can be connected to a single port of the package. For example, in the package model provided multiple Vdd_A domain pads can be connected to port PvddA1. 

The following is a sample .ploc file corresponding to the example design and package: 
<code>
Pad_A1 3125 4340 metal6 VDD_A PvddA1
Pad_A2 3225 4340 metal7 VDD_A PvddA1
Pad_A3 3325 4340 metal6 VDD_A PvddA2
Pad_A4 3425 4340 metal6 VDD_A PvddA2
Pad_B1  5125 4340 metal7 VDD_B PvddB1
Pad_B2  5225 4340 metal7 VDD_B PvddB1
Pad_B3  5335 4340 metal6 VDD_B PvddB2
Pad_B4  5335 4340 metal6 VDD_B PvddB2
Pad_VSS1  6125 4340 metal7 VSS Pvss1
Pad_VSS2  6225 4340 metal6 VSS Pvss1
Pad_VSS3  6325 4340 metal7 VSS Pvss2
Pad_VSS4  6425 4340 metal7 VSS Pvss2
...
</code>
The *.ploc file is imported into RedHawk using standard procedure.
