University VWF fault

[Altera_Forum]

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    # Model Technology ModelSim ALTERA vlog 10.3d Compiler 2014.10 Oct 7 2014 # Start time: 16:36:56 on Apr 19,2017 # vlog -work work Waveform2.vwf.vt  # -- Compiling module multiplxer_vlg_sample_tst # ** Error: Waveform2.vwf.vt(31): near "0": syntax error, unexpected INTEGER NUMBER, expecting ')'    # End time: 16:36:56 on Apr 19,2017, Elapsed time: 0:00:00 # Errors: 1, Warnings: 0       # ** Error: C:/altera/15.0/modelsim_ae/win32aloem/vlog failed.  # Executing ONERROR command at macro ./multiplxer.do line 4     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

thank you for the reply Alex, a daft question but where would i find the code?

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

 Attach 'Waveform2.vwf.vt' for starters.  Cheers, Alex

my design was built using quartus schematic, i couldnt load the file so had to zip it and then load it, thanks for taking the time to help me with this issue

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.

cheers i'll change it and give it a go,

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
