Hello all,

i describe you my problem : 

i work on Cyclone V GX (SoC) and fit on quartus prime 17.1  --> i have a qsys core connected to a nios embedded core which worked up to now.

I only add on my qsys core ,  2 Avalon master bridge (32-bit address) --> connected to different IPs ( logic part) 

It crashed and got internal error as following:

Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/vpr_common/cluster_region_tighten.c, Line: 649
[05:22:45] : [Step 3/6] Internal Error

 

impossible to know why ??? 

FYI, i test on quartus 18.1 it works...

due to project problematics we can not chang quartus version.

Can anyone help me for that ?

 thanks in avdance, 

Dhia.

Hi Dhia,


Can you running the compilation with ini "cl_region_tighten_v2_enable=off"?

This should avoid the IE.

Hello,

 

Thank you for your reply (unfortunately too late) I bypassed the problem in usign multi seed compilation and timing correction.

hwat do you mean by "  ini "cl_region_tighten_v2_enable=off"?" ==> add tcl constraint with "cl_region_tighten_v2_enable=off"

FYI, i use script compilation...

 

Thanks.

Dhia,


Noted and glad you manage to solve it.


INI file is quartus setting where you can control the quartus unlike in GUI. You You can view and change user options in the .ini file with the Tcl commands set_user_option and get_user_option in the project Tcl package. The cl_region_tighten_v2_enable=off is is to disable cluster region during compilation.
