Convert Proteus Simulation to PCB Circuit

Hey there!
In this article I’ll show you how to make a PCB of your simulated circuit using Proteus software. How to convert simulation to PCB circuit in Proteus software.
I have used an already posted project Power factor measurement using ATmega8 /16”. The link is given below you can watch whole video of this article too

Convert Proteus Simulation Circuit into PCB Ready Circuit

From the above circuit,

The oscilloscope used here isn’t needed in the final PCB, so I’m going to delete it.
By looking at the datasheet of the IC LM358 we can see that this IC has 2 units in a single chip but in this circuit 2 different IC’s are being used (U2 & U3). That’s an extra IC in the PCB which isn’t needed.
Double click on the LM358 and change the “element” value to U2:A. And the second unit to U2:B. Now there is only one IC, U2.

Use of Packaging Tool in Proteus

Every component placed in this circuit should have its corresponding PCB footprint. To check that, right click on the component and go to “packaging tool”.

You’ll see the PCB preview if footprint exists.

Finding PCB Footprint for components in Proteus

Every component has a PCB footprint but these signal inputs don’t have a PCB footprint. We have to place a two pin connector here to give signal inputs to LM358 IC.
We already deleted the oscilloscope but if you want to check signal inputs in the oscilloscope in the hardware, a two pin connector should also be connected for the oscilloscope.
However, we can search for it in the library. Open the library and goto connectors and scroll down while watching the PCB preview.
Once you find the suitable connector add it to the circuit and replace it with the signal inputs. Now everything has a PCB footprint.

PCB Layout in Proteus

Once you make sure everything is OK, You can move toward PCB designing. You’ll click on the PCB layout icon.

Component Mode in Proteus

Now goto component mode, and place all the components. You can place the components as you like.

  • Now goto selection mode. We have to draw the board edge now. It’s a way to tell the software don’t go outside this box.
  • Then goto “Design Rule Manager” in the top right corner, to set the rules you want the auto-router to follow.
  • Goto Net classes and select the Power class. As we are using only one sided PCB, I’m going to change both of the pair 1 to either Bottom copper or top copper.

  • Trace style is the thickness of the copper lines and in my experience if you are using the etching method to design the PCB the default trace is a little thin. I’m going to use T20 for Power class and T15 for signal class.
  • Similar settings for the signal class are also repeated. Now go to the “Design Rules” Tab and change the values of pad-pad, pad-trace clearance values. Pad-Pad clearance is the minimum required distance between the two pins of an IC (or adjacent IC’s).
  • Pad-Trace clearance is the minimum required distance between the copper line and a pin of IC. And trace-trace clearance is the minimum distance required between two copper lines. After setting these values click OK.

Auto Route in Proteus

  • For converting Proteus Simulation to PCB, Now go to the auto-router (2nd last Icon on the top bar) and click on Begin routing.
  • After taking some time the auto-router will finish routing. On the bottom bar you can see the progress. After auto-router has finished, if there are green lines (missing links) shown on the PCB, then it means that the autorouter couldn’t find the path to connect these terminals. You can use the “jumper wires” to get around that problem.

Adding Jumper wire in PCB Design in Proteus

  • To draw the jumper wire, you start routing and where you want to place the jumper wire you’ll double click and again double click to end the jumper wire.

Getting PCB Output from Proteus

The PCB is done now and to export it goto Output Menu in the Menu Bar and then goto “export Graphics” and choose “Export Adobe PDF File”.

We only need bottom copper. Rest of the layers will be turned off. After Exporting we can see the PCB in Pdf file.
