    Default University VWF fault

    Good afternoon,
    I was wondering if anyone could possibly offer me some help, as a mature student going back to study EE after a 20 year break I'm finding some things a little testing, I have been asked to design a matrix multiplier, I have done this by creating a chip with 3 multis and adders, when compiled it works produces a VWF, when I put 9 chips together and compile all is good but when I try to produce a VWF all I get is this message
    Top level modules: # multiplxer


    # End time: 16:36:55 on Apr 19,2017, Elapsed time: 0:00:04
    # Errors: 0, Warnings: 0

    Error.

    any help would be gratefully received
    cheers Boots

    There is an error in your code, which we can't see. Attach some code to the post for us to look at.

    Cheers,
    Alex

    Did you not write it? Is your design captured using a Quartus' schematic?

    Attach 'Waveform2.vwf.vt' for starters.

    Cheers,
    Alex

    All of your signal names start with a number. In verilog (and VHDL), all identifiers must start with an alphabetic character (a-z, A-Z) or an underscore _. It cannot start with a numeric character.

    Its annoying, because schematics allow you name name everything with a number (0-9). But this will then not work when you try and simulate it.

    Team,
    Thank you so much for the guidance, it turned out it was the naming of my signals, changed them to start with an under score and boosh sorted, waveform produced and correct
    thanks again Paul
