How to add copper layers for ground and power inner layers in 4 layer and more PCB design case. Need solution for Pulsonix PCB Design tool.

In Pulsonix we do it with Copper Pour. ( with the help of template option in insert menu )

If a copper area is to be inserted without the need for voids around unconnected tracks, components,
pads, etc then use Insert Copper facility.

Demonstrated on 
Pulsonix Version 8.0
OS  XP SP3
i3 Processor 2GB RAM

4 Layer PCB Board
- Signal TOP
-gnd    Inner 1
-power Inner 2
-Signal  BOTTOM


Moving forward. To do so first you create a template and then from the utility open pour copper and you done.

But there are some if and buts which you need to control and modify.

First thing you do before pouring or getting your copper layer. Setting up the Technology for this option.


  1. Go to setup
  2. Click at Technology ( shortcut key " T ")
  3. Under rules click at DFM /DFT Rules. And set the options as shown in below image.

      4.  You make settings for Thermal Rules and Copper Pour as per your requirements. Shown are default             settings.
      5. May be you would like to do some more. One more is in Design Setting.
      6. Setup > Design Setting or press shortcut key " Shift + D"
      7.  Look for "Template" on right side. Refer below image
     8. Next setting you do is how you prefer to add copper. For that there is one more setting.
     9. In tools > Options  [ shortcut key " O "
     10.  look for "Interaction" on right and make your setting, refer below image.
   11. You will see two options
           a) Act Poured:- In this option you add " pour copper" latter from Utilities menu.
           b) Pour On Add :- In this option as soon as you done with template. Area will get filled with copper                    right away.

To start the copper plane.

 You go to Insert >  Template and pick your desire option ploygon, rectangle, circle , line
Then start drawing it, when you done
As you can see in above image I have got my template (polygon) in golden colour. And dark green is my Board outline outline.

To Assign net name to the plane / template. Select any one side of template ( in above image is in light green colour) then right click on it > Net > Change Net (  or simply Press " F2 "  on your keyboard ).
Change Net window will appear from the drop down menu you will be able to select your desired net and then press OK.
Click at " Pour Copper" from Utilities
And you done you PCB will look like as shown in below image just an example
Please note:- If you got track for other signal, you see void ( space / clearance ) around them otherwise full plane.

If wanna two GND Plance or two power plane
Then you need split plane click here to learn more
