Replace the .sopcinfo file with a new one and regenerate BSP ... possible ?

Question

Hello,

I'm trying to compare different different versions of the same system.

I envisage the following approach:

Make modifications in qsys and save new system as system1.qsys (let say that original was system.qsys)
Generate new design in qsys ... new file system1.socpinfo is created
Change instantiation of the new system1 in a top-level module, i.e. system U0 becomes system1 U0.
Compile new design
Program board with new .sof
And at this step (when passing to Eclipse), the problem arises ... how to specify new .socpinfo and regenerate bsp

Probably step 6 is merely unrealizable and one should create new bsp and specify it in application ?

Does exist a straightforward approach for evaluation of different versions of qsys system ?

Thanks in advance ?

Probably the best approach to test different versions of qsys design is as follows:

Generate new .qsys (also generates new .socpinfo)
Add this new .qsys to design and remove the previous one
Instantiate this new .qsys in the top module (also comment the previous one ... and optionnally modify port list)
Compile design in Quartus
Program board with newly generated .sof
In Eclipse: generate new bsp based on new .socpinfo
In Eclipse: specify new bsp in application properties
In Eclipse: rebuild application ... and run it on board

So, afterwards, when one needs to switch to a different configuration (already built), it should iterate trough steps 2 ... 8.

Am I correct ?
