Max10M-16-SA-U-169 program without having the project file

Hi, I am trying to program the already designed and programmed Intel Max 10M-16-SA-U-169  to change the states of some of the components connecting to the FPGA. I do not have the project file and the pin assignment of the FPGA. I only have some .pof files that I can program the FPGA through the JTAG connection with a USB blaster. Is there any way to access the design of the FPGA through Quartus, or is there any way to do it with any other tools or software? Can I find out the pin assignment of the FPGA? I would appreciate it if anybody could help me with this situation.

    Hi, boundary scan logic allows also to change data direction (enable/disable tri-state drivers) and set output state of pins. You can e.g. read or write memory devices connected to FPGA pins. There are various BSDL tools available,  I'm e.g. using TopJTAG Probe with USB-Blaster and Altera FPGA.

    Hi,

    retrieving pin configuration and netlist from configuration bitstream isn't supported by vendor provided or commonly available tools. Scientific papers demonstrated however basic feasibility for unencrypted configuration files.

    Data direction and state of IO-pins of configured FPGA can be observed in operation with boundary scan tool.

    Regards

      Thank you, Frank, for the response. With this method, only the state of the pins can be detected, so it cannot find the pin configuration. Another question is whether it is possible to change the state of the pins while they have been detected in this way?

    Hi Mahmoud,

    Frank is correct, you can’t recover pin assignments from the bitstream, but with boundary-scan you can both observe and drive pin states by enabling outputs and setting values using tools like Quartus Programmer or TopJTAG. Just ensure you have the correct BSDL file and avoid driving against active outputs to prevent contention.

        Hi Fakhrul, 

        Thank you for the response and help. For now, I need to try the boundary scan to see if I can find the required information. 

         Best Regards,

        Mahmoud
