Hai

All

 

I'm looking info's about how's to reverse the gerber files to boards/schematics to edit in the CAD/CAM Programs.

 

Kindly share information

I think that is called stealing IP or counterfeiting...........

Not sure if you want to go that route here.........

PCB - most decent PCB software can import Gerber files so that you can edit them.

Schematics - you can't. It is a manual process.

#1 Hardware Problem? https://www.avrfreaks.net/forum/...

#2 Hardware Problem? Read AVR042.

#3 All grounds are not created equal

#4 Have you proved your chip is running at xxMHz?

#5 "If you think you need floating point to solve the problem then you don't understand the problem. If you really do need floating point then you have a problem you do not understand."

Yup - a Gerber is just a map of where the copper is, and therefore where the connections are. If you have a gerber or a pcb, it's a question of starting in one corner and working through all the connections until you have a rats nest schematic, which you need to shake up and make into something legible. In practical terms, this is effectively impossible without a huge expenditure of time and effort for anything with hidden layers. You might look up BigClive on YouTube; he tends to unwind some simple widgets that he investigates.

A Gerber is a file type that assumes that you are dragging a dot light source over an unexposed photo film.

It uses coded number instructions to do things like:

   select #1 light source width

   move the light source (with light off) to this X:Y co-ordinate.

   turn light source ON

   move to this co-ordinate in a straight or diagonal line

   turn light source OFF

   select #2 light source width

   ...etc

 

Look for a program that converts the Gerbers into a PCB board layout.

Then identify the components (what the ICs are) and then recreate the schematic.

Also, try looking at how CNC machines deal with this situation.
