Migrating from Quartus 9.1 to 13.1

[Altera_Forum]

Hi everyone, 

All of our projects are under Quartus II 9.1, and we were thinking of upgrading it to the 13.1 version. Do you know if there is any compatibility problem if we migrate our projects from 9.1 to 13.1 ?

You might have to re-generate some IP cores such as PLLs and Nios II etc.

Yes the migration issues really depend on the IP you are using. 

 If you are using SOPC builder and NIOS the difficulty is higher than if you are just using memories and PLL's but you may need to regenerate code IP blocks in either case.  I have taken a design from Quartus 6 to 13.1 through the various versions in between. The primary issue I had was with the FFT core changing it's IO interface at one point, but most designs will compile with little issues.  Pete

Triple Speed Ethernet (if you use it) core needs to be manually replaced to newer one in 13.1.

You can try to open your 9.1 QAR with 13.1 to see if there is any auto-upgrade performed or any warning prompting on core need to be regen. Then regen the specific cores.

Thank you all for your replies !

you are welcome.

this is something from SOPC to never QSYS based design. I not sure what is your design, i guess if not consists of many complicated components, you may just rebuild directly with v13.1 .

There were quite a few issues with QSYS, PCIe, and Transceiver cores, but at the end everything was resolved.
