Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/quartus_interface/qi_common/vpr_qi_soft_constraint_manager.cpp, Line: 1513
Quartus II 32-bit Version 11.1 Build 173 11/01/2011 SJ Full Version ---------------- Hi My steps are 1, compile project, success 2, use Signaltap (which means project need to be re-compiled) 3, re-compile project, error happens. Anyone shed a light ? Thanks PS: We've searched extensively. Interestingly, quite some solutions/pacthes are available to solve similar problems, but not this one we have. For example, you can google another error as below, and find its solution patch immediately: "Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/quartus_interface/ qi_common/vpr_qi_high_speed_low_power_tiles.cpp, Line: 5985" --------------- Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/quartus_interface/qi_common/vpr_qi_soft_constraint_manager.cpp, Line: 1513 Internal Error Stack Trace: 0x1c86ea: _vpr_qi_jump_to_exit + 0x64 (fitter_vpr20kmain) 0x2820ac: _pl_move_add_block + 0x1e8 (fitter_vpr20kmain) 0x2820e5: _vpr_exit_at_line + 0x37 (fitter_vpr20kmain) 0x1fb970: _handle_assertion_failure_stripped + 0x25 (fitter_vpr20kmain) 0x36632a: _vpr_qi_scm_update_clustering_information_after_netlist_change + 0x2d (fitter_vpr20kmain) 0x39fb5d: _aa_rt_dchain_adjust_delays_to_include_delay_chains_used_in_ic_delay + 0x119 (fitter_vpr20kmain) 0x3ae745: _aa_pl_rebuild_netlists_after_atom_netlist_modification + 0x17b (fitter_vpr20kmain) 0x1c3a68: ___sse2_available_init + 0x95bb4 (fitter_vpr20kmain) 0x115d86: _aa_postpl_do_post_placement_ops + 0x16 (fitter_vpr20kmain) 0xf8d9f: _vpr_qi_llr_back_annotate + 0x15f (fitter_vpr20kmain) 0xfef6c: _aa_flow_fit + 0x5c (fitter_vpr20kmain) 0xed312: _vpr_main_internal + 0x2b2 (fitter_vpr20kmain) 0x115c7a: VPR_QI_FACADE::vpr_qi_main + 0xfa (fitter_vpr20kmain) 0x2d5c2: _fitapi_run_vpr + 0x72 (fitter_fitapi) 0x3934d: FITCC_EXPERT::run_vpr + 0x11d (FITTER_FITCC) 0x3a40c: FITCC_EXPERT::place_and_route + 0x13c (FITTER_FITCC) 0x3b8f1: FITCC_EXPERT::invoke_fitter + 0x701 (FITTER_FITCC) 0x2bda: _ftitan_execute + 0x22a (fitter_ftitan) 0x9c10: fmain_start + 0x710 (FITTER_FMAIN) 0x7c1c: qfit_execute_fit + 0x19c (quartus_fit) 0x12275: QFIT_FRAMEWORK::execute + 0x4b5 (quartus_fit) 0xff71: qexe_get_command_line + 0x14c1 (comp_qexe) 0x12474: qexe_process_cmdline_arguments + 0x3d4 (comp_qexe) 0x12563: qexe_standard_main + 0x83 (comp_qexe) 0xbfae: qfit_main + 0x5e (quartus_fit) 0x1c51: msg_main_thread + 0x11 (CCL_MSG) 0x1be8: _thr_final_wrapper + 0x8 (ccl_thr) 0x1bc5: msg_thread_wrapper + 0x85 (CCL_MSG) 0x443a: mem_thread_wrapper + 0x4a (ccl_mem) 0x2b5d1: msg_exe_main + 0x81 (CCL_MSG) 0xc44c: _main + 0x1c (quartus_fit) 0x14377: _memset + 0x15f (quartus_fit) 0x51113: BaseThreadInitThunk + 0x11 (kernel32) 0x5b428: RtlInitializeExceptionChain + 0x62 (ntdll) 0x5b3fb: RtlInitializeExceptionChain + 0x35 (ntdll) End-trace Quartus II 32-bit Version 11.1 Build 173 11/01/2011 SJ Full VersionLink Copied

I get this in 12.0. Haven't submitted an SR yet, but found that reducing the signaltap size and number of signals helps.

This is an interesting error. I have not seen this one before. I think it is hard to say what the root cause of the error is. One suggestion, however, would be to shorten the data depth for the signals (say if you were at 2K, try 512 or even smaller) and see if that makes a difference. Best, James

Thanks jderrick and James.
Installed Quartus II version 12 and use this version 12. Now the SignalTap II works, even 5 signals are probed at the same time. Did not expect solve the problem in this way ...
