Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/vpr_common/utils

[Altera_Forum]

Any ideas why it may happen? 

I just added a PLL to my project based on golden design for Cyclone V SoC devkit. Now, I cannot move forward in compiling the design even when removing PLL instance from top level module.  --Dmitry  Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/vpr_common/utils_profiling.c, Line: 538   Internal Error  Stack Trace:  0x119632: vpr_qi_jump_to_exit + 0x58 (fitter_vpr20kmain)   0x43daaf: vpr_final_exit + 0x8 (fitter_vpr20kmain)  0x4460e2: vpr_exit_at_line + 0x57 (fitter_vpr20kmain)  0x1d7c58: profile_close_bin + 0x338 (fitter_vpr20kmain)  0x235dc3: vpr_report + 0x13 (fitter_vpr20kmain)  0x792f8: VPR_QI_FACADE::vpr_qi_main() + 0x28 (fitter_vpr20kmain)  0x3d870: fitapi_run_vpr + 0x60 (fitter_fitapi)  0x3febe: FSV_EXPERT_BASE::place_and_route(bool*) const + 0x16e (fitter_fsv)  0x444e0: FSV_EXPERT_BASE::invoke_fitter() const + 0x17e0 (fitter_fsv)  0x3e402: fsv_execute + 0x292 (fitter_fsv)  0x2cac5: fmain_start(CMP_FACADE*) + 0x565 (fitter_fmain)  0x1b840: qfit_execute_fit(QCU_FRAMEWORK*, QFIT_FRAMEWORK*) + 0x150 (comp_qfit_legacy_flow)  0x15afd: QFIT_FRAMEWORK::execute() + 0x2ad (comp_qfit_legacy_flow)  0x25651: qfit_legacy_flow_run_legacy_fitter_flow + 0x1a1 (comp_qfit_legacy_flow)   0x2e8f6: TclInvokeStringCommand + 0x76 (tcl8.5)  0x32b1e: TclEvalObjvInternal + 0x2be (tcl8.5)  0x34310: TclEvalEx + 0x4f0 (tcl8.5)  0x34d13: TclEvalObjEx + 0x393 (tcl8.5)  0x3ac31: Tcl_EvalObjCmd + 0x91 (tcl8.5)  0x32b1e: TclEvalObjvInternal + 0x2be (tcl8.5)  0x73abf: TclExecuteByteCode + 0x151f (tcl8.5)  0xb5bc7: TclObjInterpProcCore + 0x107 (tcl8.5)  0x32b1e: TclEvalObjvInternal + 0x2be (tcl8.5)  0x73abf: TclExecuteByteCode + 0x151f (tcl8.5)  0xb5bc7: TclObjInterpProcCore + 0x107 (tcl8.5)  0x32b1e: TclEvalObjvInternal + 0x2be (tcl8.5)  0x34310: TclEvalEx + 0x4f0 (tcl8.5)   0x98c70: Tcl_FSEvalFileEx + 0x230 (tcl8.5)  0x98d6e: Tcl_EvalFile + 0x2e (tcl8.5)  0xff62: qexe_evaluate_tcl_script(char const*) + 0x43b (comp_qexe)  0x15515: qexe_do_tcl(QEXE_FRAMEWORK*, char const*, char const*, _Dinkum_std::list<_Dinkum_std::basic_string<char, _Dinkum_std::char_traits<char>, MEM_STL_ALLOCATOR<char> >, MEM_STL_ALLOCATOR<_Dinkum_std::basic_string<char, _Dinkum_std::char_traits<char>, MEM_STL_ALLOCATOR<char> > > > const&, bool, bool) + 0x507 (comp_qexe)  0x16352: qexe_run_tcl_option(QEXE_FRAMEWORK*, char const*, _Dinkum_std::list<_Dinkum_std::basic_string<char, _Dinkum_std::char_traits<char>, MEM_STL_ALLOCATOR<char> >, MEM_STL_ALLOCATOR<_Dinkum_std::basic_string<char, _Dinkum_std::char_traits<char>, MEM_STL_ALLOCATOR<char> > > >*, bool) + 0x542 (comp_qexe)  0x32bbe: qcu_run_tcl_option(QCU_FRAMEWORK*, char const*, _Dinkum_std::list<_Dinkum_std::basic_string<char, _Dinkum_std::char_traits<char>, MEM_STL_ALLOCATOR<char> >, MEM_STL_ALLOCATOR<_Dinkum_std::basic_string<char, _Dinkum_std::char_traits<char>, MEM_STL_ALLOCATOR<char> > > >*, bool) + 0x7b1 (comp_qcu)  0x18b1f: qexe_standard_main(QEXE_FRAMEWORK*, QEXE_OPTION_DEFINITION const**, int, char const**) + 0x641 (comp_qexe)  0x9517: qfit2_main(int, char const**) + 0xe7 (quartus_fit)  0x3bb9a: msg_main_thread(void*) + 0x10 (ccl_msg)  0x75bc: thr_final_wrapper + 0xc (ccl_thr)   0x3c801: msg_thread_wrapper(void* (*)(void*), void*) + 0x5b (ccl_msg)  0x18bf5: mem_thread_wrapper(void* (*)(void*), void*) + 0xc5 (quartus_fit)  0xf41d: err_thread_wrapper(void* (*)(void*), void*) + 0x27 (ccl_err)  0x799c: thr_thread_wrapper + 0x15 (ccl_thr)  0x4e41d: msg_exe_main(int, char const**, int (*)(int, char const**)) + 0x96 (ccl_msg)  0x21ec5: __libc_start_main + 0xf5 (c.so.6)  0x8d69: __gxx_personality_v0 + 0x311 (quartus_fit)     End-trace     Quartus II 64-Bit Version 13.1.0 Build 162 10/23/2013 SJ Web Edition

Hi Dmitry, 

 Was it possible to see the messages from Quartus prior to the internal error? May be there was a warning or error message that could give a clue about what caused this, sometimes there is.   Regards J

The message itself make no sence for me as device is used for about 10% only.

Hi, 

 Even though the error message may not make sense from a device utilization perspective, it does (hopefully) point you in the right direction. Do you use this reset signal to reset the PLL you added to the design? Would it be possible for you to try another reset strategy in that case?  I see in the initial post that you seem to get the IE even when the PLL is removed. Try to delete all Quartus generated folders in your project directory (db, incremental_db etc) and start the compilation again.  Cheers
