HLS compiled qsys modification and regeneration problem

Hi everone,

I came across a question about modifying HLS generated qsys and regeneration of the modified system.

My quartus SDK compiler is 15.1.

I compiled a .cl file using command "aoc -s -v  ().cl --board (board_name)".

A qsys named system.qsys had been generated. Next I modified this system by adding some customised components.

After saving ths system, I regenerated this system.qsys into .v file. The command I used for regenerate was 

'qsys-generate system.qsys --synthesis=VERILOG --family="CYCLONE V" --simulation=VERILOG'.
 
After doing this, however, the system.v was not shown in the synthesis folder. Nor was it shown in simulation folder.
 
Before regeneration, I had already removed all HLS generated system folder and "system.tcl" file. However, the system.v was still not there.
 
May I ask if the .v file has been hidden or something else happened? 
 
I have also attached the whole project for your references.
 
Thank you very much!

Hi everyone,

A new update here:

when I use aoc -v to compile the project, some strange messages occur:

May I ask has anyone come across this before?
 
It seems that my defined IP has problems, but don't know why it has problems..
 
Thank you again!
