Compilation failure in Quartus 13 "Node is missing source"

[Leire]

Hi all,

I am using Quartus 13.0.1 sp1 to compila a project and generate the "pof" file for a CicloneII. In one of the block diafram file (bdf) I use a signal in the form of an array bit that is not assigned to any value. But the compiler does NOT detect it. It should give me a "Source is missing" error, shouldn't it? I can not find the compile option that can affect such error. Nor does any associated warning appear.

Has anyone had aproblem similar to mine?

Thanks in advance,

Leire

Leire,

Can you show what is the error message in compilation report?

Hi SyafieqS,

There is NO error in compilation report. That is what susprises me. The signal "q_pru[16]" is not assigned, not connected, to any source. The problem I have is there is no error, no warning in the compilation report.

Thanks in advance,

Leire

So if there's no error or warning, how do you know there is an issue?  Is it not working correctly in hardware?  Are you seeing something strange in the RTL Viewer or Technology Map Viewer (Post-fit)?

Can you try to hit analysis and elaboration button in Quartus?

See if there warning/report able to tell.

Hi SyafieqS,

Sorry for not replying earlier.

As you commented, I realize that there is a warning associated, that indicated the pin is STUCK at GND.

What is strange is that if I have a defined reg[15..0] and a I use the undefined reg[16] or reg[17] it appears this warning. However, if I use the undefined reg[18], reg[19] and so on, it appears an error saying "Node reg[18], reg[19] is missing source".

Thanks a lot,

Leire
