Hello all,

I re-open this post, because i stil have place and route problem with this error :

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

i tried to add tcl constraint : set_user_option -name CL_REGION_TIGHTEN_V2_ENABLE OFF

but quartus do not recognize it. i have this error :

ERROR: Illegal user option name: CL_REGION_TIGHTEN_V2_ENABLE. Specify a legal user option name. To get a list of legal names, use the "get_all_user_option_names" command

Can anyone help me for that ?

FYI, i use quartus 17.1

Thanks in advance.
