Detection of CPLD successfully configured.

Hi All, I am working on a board with CPLD and three other FPGAs. I am able to configure the CPLD using it's pof file. My question is, is there a way to indicate that the CPLD is configured correct...

    Hi,

    In case of custom board, I believe it should have some test points/nodes where you can make use of probes for multi-meter or Oscilloscope.

    you can make a use of simple D Flipflop code for checking the status of particular pin of CPLD.

    Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

    Best Regards

Thank you for your reply.

Yes I have done the pin mapping correctly and configured the CPLD using the .pof file. It is successful too.

I have a custom board and I have not connected the push button/slide switch to the indicator pin. Though it is connected to the LED.

Shall I write some lines of VHDL code to indicate the CPLD_DONE pin should go high once the the configuration is complete?

I don't think so but please let me know if I am missing anything.

Thank you
