lvds with max10 eval board

[Altera_Forum]

I am trying to interface ADC (LTC2264) to max10 via LVDS interface. The ADC provides clock, frame and serial data, all as LVDS signals. I need just to interface LVDS to max10, then sample the data; no PLL necessary 

When I define a single pair as LVDS (e.g. DIFFIO_R14P_CLK2P/N) in the assignment editor, the compilation stops with message "Sorry The QuartusII software quit unexpectedly"; the last message "Warning (171167): Found invalid Fitter assignments. See the Ignored Assignments panel in the Fitter Compilation Report for more information". Because of the compilation crash there is no Ignored Assignments panel in the report. Details of the crash are shown below.  Before the LVDS definition of the pair the project compiles and works correctly.  Any help is greatly appreciated.  Thank you, Vitaly  problem details Error: Internal Error: Sub-system: FIOMGR, File: /quartus/fitter/fiomgr/fiomgr_io_bank.cpp, Line: 4427  new_type != DEV_CURRENT_STRENGTH_DEFAULT  Stack Trace:   0x38733: FIOMGR_IO_MANAGER::is_lvds_pad_spacing_lab_row_based + 0x21053 (FITTER_FIOMGR)   0x36335: FIOMGR_IO_MANAGER::is_lvds_pad_spacing_lab_row_based + 0x1ec55 (FITTER_FIOMGR)   0x150b99: FIOMGR_STRATIXIII_DYNAMICTERMINATIONCONTROL_LEGALITY::operator= + 0x94949 (FITTER_FIOMGR)   0xa325a: FIOMGR_IO_MANAGER::warnings_check + 0x35a (FITTER_FIOMGR)   0xc17d: fcuda_execute + 0x2a9d (fitter_fcuda)   0x512c7: FITCC_EXPERT::fitter_post_cleanup + 0x57 (FITTER_FITCC)   0x52d26: FITCC_EXPERT::invoke_fitter + 0xc86 (FITTER_FITCC)   0x98d7: fcuda_execute + 0x1f7 (fitter_fcuda)   0xe142: fmain_start + 0x8e2 (FITTER_FMAIN)    0x14410: TclInvokeStringCommand + 0xf0 (tcl86)   0x161e2: TclNRRunCallbacks + 0x62 (tcl86)   0x17a65: TclEvalEx + 0xa65 (tcl86)   0xa6f8b: Tcl_FSEvalFileEx + 0x22b (tcl86)   0xa5646: Tcl_EvalFile + 0x36 (tcl86)   0x13962: qexe_evaluate_tcl_command + 0x582 (comp_qexe)   0x12adc: qexe_apply_ini_vars + 0x29ec (comp_qexe)   0x17c05: qexe_run_tcl_option + 0x575 (comp_qexe)   0x34b13: qcu_run_tcl_option + 0xb63 (comp_qcu)   0x1755a: qexe_process_cmdline_arguments + 0x246a (comp_qexe)   0x18381: qexe_standard_main + 0xc1 (comp_qexe)    0xcad8: msg_initialize_out_of_memory_handler + 0x378 (CCL_MSG)   0xe20c: msg_set_stack_size + 0x7c (CCL_MSG)   0x5aa0: mem_gen_get_project_output_directory + 0x64 (ccl_mem)   0xc721: msg_exe_main + 0xa1 (CCL_MSG)    0x159cc: BaseThreadInitThunk + 0xc (kernel32)   0x2b980: RtlUserThreadStart + 0x20 (ntdll)   End-trace   Executable: quartus_fit Comment: None system information Platform: windows64 OS name: Windows 7 OS version: 6.1  quartus ii information Address bits: 64 Version: 14.1.0 Build: 186 Edition: Web Edition

This is the Quartus II internal error. I think you should file a service request to Altera to report this and ask if there is any workaround. Alternatively, you could also try with the latest Quartus II 15.0 to see if similar error still occur.

I tried ver 15.0 and it compiled.  

Thank you!

You are welcome. Glad that the 15.0 works for you.
