MUX16

[SpartanHalo]

Hi guys,

this is my code:
CHIP Mux16 {
    IN a[16], b[16], sel;
    OUT out[16];

    PARTS:
        Mux(a=a[0], b=b[0], sel=sel, out=out[0]);
    Mux(a=a[1], b=b[1], sel=sel, out=out[1]);
    Mux(a=a[2], b=b[2], sel=sel, out=out[2]);
    Mux(a=a[3], b=b[3], sel=sel, out=out[3]);
    Mux(a=a[4], b=b[4], sel=sel, out=out[4]);
    Mux(a=a[5], b=b[5], sel=sel, out=out[5]);
    Mux(a=a[6], b=b[6], sel=sel, out=out[6]);
    Mux(a=a[7], b=b[7], sel=sel, out=out[7]);
    Mux(a=a[8], b=b[8], sel=sel, out=out[8]);
    Mux(a=a[9], b=b[9], sel=sel, out=out[9]);
    Mux(a=a[10], b=b[10], sel=sel, out=out[10]);
    Mux(a=a[11], b=b[11], sel=sel, out=out[11]);
    Mux(a=a[12], b=b[12], sel=sel, out=out[12]);
    Mux(a=a[13], b=b[13], sel=sel, out=out[13]);
    Mux(a=a[14], b=b[14], sel=sel, out=out[14]);
    Mux(a=a[15], b=b[15], sel=sel, out=out[15]);
}


Hardware simulator says "Comparison failure at line 4".

I don't understand because....

[WBahn]

because... why?

I'm not a mind reader -- I can't divine what or why you don't understand something.

What does the comparison file say for Line 4?

What does your output file say for Line 4?

Which one (if either) do you agree is correct?

[WBahn]

Also, which tool are you using? The online web-based tools or the offline tool suite?

Another post indicated that the web tools seem to be sensitive to indentation (which would be a bug). I notice that your first part is indented differently than the others. You might try cleaning that up, just in case.

'conoarison failure's means that the result of running the simulation is wrong. The tool shows you the output of your circuit and the expected output. Line 4 is the line in the comparison file, not the line in your source code

Right! Excuse me but yesterday I was so tired and I posted without some important details.


a a[4] 0
b b[4] 1
sel sel 0
out out[4] 1


This is the output

No web based but desktop software

[SpartanHalo]

This is the output

a a[4] 0
b b[4] 1
sel sel 0
out out[4] 1


Out should be 0

Guys,

it was a problem in original MUX.hdl, now it's correct!

I'd fixed the code of MUX.hdl


Thank you so much for the support!
