Quartus II 14.0 compatibility issue with 13.0

Altera_Forum · ‎09-12-2016

Hi All,

I have a question regarding compatibility issue.

I have recently installed Quartus II 14.0 in my laptop.

When I tried to use colleague’s project file (.qar) to re-generate binary file (.sof), it didn’t seem to function properly.

After I programmed .sof file, motor didn’t travel smoothly, but rather bumpily.

I found that my colleague was using Quartus II 13.0.

And I installed Quartus II 13.0 and re-compile the same project, then the FPGA image worked fine.

Here is detail information of Quartus version.

Colleague: Quartus II Web Edition 13.0.1 Build 232 SP1

Mine: Quartus II 14.0.0 Build 200 SJ Full Version

I assume that the latest version (14.0) should support old version (13.0), but is there any compatibility issue with it?

I appreciate your help.

Regards,

Byung Hwa Kim

Is there any Altera IP in the project? If so, was it re-generated prior to running it through Q14?

I'm not convinced this is the issue. However, without quite a bit more to go on we're going to be guessing somewhat...

Cheers,

Alex

There are a few things that could cause this....

1. Is the design fully synchronous? did it meet timing? If it is not fully synchronous, then the move to a new version and recompile is going to affect the timing of the design.

2. Any IP used? was it upgraded for a new version?
