Quartus II 13.1.0 - different file size of the rbf file generate with two different computer.

[BoonChin]

Hi, I am using quartus II 13.1.0 to compile my project. The board i using is Cyclone III. I having two computers with me and compile the same source code. Both of them generate two different size of the rbf file. The file with smaller size cannot operate at all while another rbf file can program FPGA and run successfully. the two rbf file sizes are 644KB and 604KB.

You don't say what OS/environment each of the computers is using, so hard to provide any constructive comments.

As a start, I would just reinstall the Quartus software from a new download on the 'bad' computer.

Hi _AK6DN,

I am using Window 10, another computer also using same window which is window 10, I have try to reinstall the quartus software, still does not change anything.

Then I would go into each design directory, remove all temporary and intermediate files, and force a full recompile from scratch.

alright, let me try and see

Try to recompile it after deleting the qdb and temp files. Does that resolve the issue. Diff env machine expected diff output and does not assure the similarity (small margin e.g. timing etc)

[BoonChin]

Hi, Where is the qdb and temp file? is these file inside the output file? i cannot find it

[SyafieqS]

Judging the size that seem reasonable and as long as not by huge margin e.g 700kb and 600kb etc

[SyafieqS]

Normally there is quartus database file consisting information related to synthesis, mapping etc. the file should be named e.g. qdb (if im not mistaken) or just compile the desing from scratch. Also just to be clear that that to me seem expected output (diff env and machine, lead to diff map/route/fitt/) and there should not be a concern.

Hi, I think I found the reason that generate two different file size. It is because directory have of the initialization of memory have been set in wrong directory. That why in two different pc generate two different file size of rbf file. One of them cannot find the initialization file, therefore it have lower file size of the rbf file.

Thank you very much for giving me advise and solution in this.

Still cannot find any qdb or temp file, i have try to recompile everything again with 6 computer, 5 of them is the same, there only 1 computer that generate different size of rbf file. Is there any setting that will affect the file size?

[_AK6DN_]

In your design directory (ie, wherever your DESIGN.qpf file is located) there should be these directories (folders)
created after a compile:

• db
• incremental_db
• simulation

The last one is optional depending on your project settings. Just delete those three folders and their contents.

There are also a bunch of .rpt .summary .map .pin & etc files in your design directory, but they will just be rebuilt, they don't affect a compile.
