Obtain the schematic circuit by pcb

[tnnelectro]

Hi,

I scanned a printed circuit board, and I got the file PCB made OMNIGLYPH (CIRCAD ...),

with all the components already in place.

There is a program to obtain from file PCB, the schematic (wiring diagram)?

NB: I can convert PCB file Circad TANGO II or in other formats ...

It would be a great help to find a solution, thanks.

I never heard of such a program. One usually has to trace the components and connections and reconstruct the schematic diagram manually.

Looks like Circad has a way of Reverse Engineering a single sided PCB:

Yes I know,

but the PCB file already exists.

I have to get the wiring diagram from PCB ...

It appears you may have to manually place lines and components using 'PL' and 'GC' commands after scanning. Then the software completes the file.
They have a complete section on getting started!
As the saying goes, RTFM.

Do you not have the Circad software? If you do does it create an image of the PCB? If so can you just do a screen-print and use their reverse engineering option.
Or do you just have the file with no supporting software? If so, maybe you could you could start a thread on this forum (or other forums where you posted): "Can someone image a CIRCAD PCB file for me?"

My guess is that my colleagues have misunderstood you. I think you're asking if your PCB software or other software can convert a PCB to a schematic. Not that I know of.

What you want to do is called "reverse engineering". For simple circuits it's not hard to do but takes skill and experience for larger circuits.
