Converting a PCB layout back into a circuit diagram, also known as schematic extraction or reverse engineering, is a process often required to understand the design of an existing board. While various tools and methods exist, one specific approach involves utilizing specialized software and file formats.
Converting Using E-Studio and EDIF
Based on the provided information, a specific method for converting a PCB layout (presumably represented initially in a format that can generate an EDIF file) to a schematic involves the use of E-Studio software and the EDIF file format. EDIF (Electronic Design Interchange Format) is a vendor-neutral format used for exchanging electronic design data.
Here are the steps involved in this particular conversion process, as described in the reference:
- Start E-Studio Software and Open the EDIF File: Begin by launching the E-Studio software. Then, open the EDIF file that was generated from the PCB layout data in a preceding step (Step 2, according to the reference, although the method for generating this EDIF file from the PCB layout is not detailed in the provided text).
- System Window Appears: Upon opening the EDIF file in E-Studio, the system will display a pop-up window.
- Save the Schematic: Within the pop-up window, locate and click the "Save" option to save the generated schematic.
- End the Process: Following the save action, click the "OK" button in the subsequent pop-up window to complete the conversion process.
According to the reference, the resulting schematic file can then be opened and viewed in ORCAD. It is also noted that the generated drawings might appear "a bit big."
This method highlights a specific toolchain involving an EDIF file, E-Studio for the conversion process, and ORCAD for viewing the final schematic.
