Hi,
I'm not very experienced with FPGAs. Can some one help me with the following problem please! I did "Analysis an Elaboration" on my design and it was successful. Then I tried "Analysis and Synthesis" and I get the following error. I guess it is related to timing and .sdc file. Can someone give me a clue how to resolve this problem? ----------------------------------------- Internal Error: Sub-system: SSC, File: /quartus/tsm/ssc/ssc_timing.cpp, Line: 93 !use_relaxed_slacks || (tdc_edge_slacks != 0) Stack Trace: 0xf460: SSC_UTIL::compute_average_lut_delay + 0xed0 0x10b77: SSC_UTIL::perform_timing_analysis + 0x467 0x342ce: sutil_ssc_perform_timing_analysis + 0x1be 0x68b6f: MAP_TESLA::set_lut_cost + 0x400f 0x670e0: MAP_TESLA::set_lut_cost + 0x2580 0x26d7e: FTM_ROOT_IMPL::lutmap + 0x54e 0x24392: FTM_ROOT_IMPL::start_normal_flow + 0x152 0x23909: FTM_ROOT_IMPL::start + 0x149 0x23008: FTM_ROOT::start + 0x128 0x604a3: scl_start + 0x5ab83 0x6101d: scl_start + 0x5b6fd 0x65113: scl_start + 0x5f7f3 0x2ebb5: scl_start + 0x29295 0x2f7b7: scl_start + 0x29e97 0x2fcff: scl_start + 0x2a3df 0x5435: scl_run_parallel_mls_script + 0xf95 0x11fad: qexe_get_command_line + 0x1b7d 0x14e0e: qexe_process_cmdline_arguments + 0x59e 0x14f21: qexe_standard_main + 0xa1 0x4ae8: msg_exe_fini + 0x58 0x522c: msg_exe_fini + 0x79c 0x1524: MEM_SEGMENT_INTERNAL::~MEM_SEGMENT_INTERNAL + 0x194 0x5e0f: msg_exe_main + 0x8f 0x159bc: BaseThreadInitThunk + 0xc 0x2a2e0: RtlUserThreadStart + 0x20 End-trace Quartus II 64-Bit Version 13.0.0 Build 156 04/24/2013 SJ Web EditionLink Copied

This is a crash - no idea what caused it. Try a newer version of quartus or raising a support ticket.

--- Quote Start --- This is a crash - no idea what caused it. Try a newer version of quartus or raising a support ticket. --- Quote End --- Thank you. I did file a service request. But I guess it has something to do with the timing. As I was trying to do analysis and elaboration, I was getting error for my verilog.v file. Finally I resolved that problem and now I'm getting this problem. I have minimum experience with creating .sdc file.
