Modelsim Warning: (vlog-2083) <protected>(<protected>): Carriage return (0x0D) is not followed by a newline (0x0A)

Ask Question

I'm getting this warnings, that are very annoying because it floods all the transcript, and I don't know why they appear just after "loading/running" the file C:/intelfpga_pro/18.0/quartus/eda/sim_lib/mentor/twentynm_hssi_atoms_ncrypt.v -work twentynm_hssi

How can I get rid of this warnings?

In the original Intel forum post is attached the full transcript:

thanks

Do you have broken text files that have an embedded \r alone? It sounds like the program you're using wants DOS line endings. If they're supposed to be newlines (like if this file was from a classic-Mac?), maybe tr '\r' '\n' < input > output or any equivalent way of converting line endings. – Peter Cordes Aug 22, 2018 at 14:45 I've checked the file with notepad++ and it's a compiled file with the corresponding "\r\n" at the end of all the lines – taquionbcn Aug 23, 2018 at 15:07 But are there any stray \r characters not at the ends of lines? This program is claiming there are, so maybe use a hex editor or something else to search for them. – Peter Cordes Aug 23, 2018 at 15:14 I've done a recheck of the files and made the necessary changes so now all the lines on twentynm_hssi_atoms_ncrypt.v and twentynm_hip_atoms_ncrypt.v end with \r\n and there is no \r alone. Also I'm trying to contact mentor but for some reason I can do an SR to all the products of mentor I have license but not for modelsim. – taquionbcn Aug 24, 2018 at 8:04

This looks like a Modelsim SE 10.7 issue as Modelsim 10.2c (which I still have) compiles the file without any issues.

Top level modules:

So you could try an older version of Modelsim SE and report this bug to Mentor (it also fails with Questa 10.7b).

Good luck, Hans.

Part of the previous comment was answering you, I'm trying to contact mentor but for some reason I can do an SR to all the products my organization have license but not for modelsim, I have send a service request to the TI department and when they solve this issue I will be able to talk with someone of mentor. – taquionbcn Aug 24, 2018 at 8:12

I have answer from Mentor,

the problem, as Peter Cordes said, is the \r alone but this happens inside the protected compiled code, so only intel can solve this warning.

Meanwhile I can suppress this warning by adding the “-suppress 2083” in the vlog line.

Thanks
