Re: Internal Error: Sub-system: VPR20KMAIN altera_arch_route_lookahead
Hi @RichardTanSY_Altera Update on the progress. I did update from 17.0 to 19.1 (latest version currently available within the company) and the issue persists. Problem Details Error: Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/altera_arch_common/altera_arch_route_lookahead.cpp, Line: 4320 Internal Error Stack Trace: 0xc7b1c: vpr_qi_jump_to_exit + 0x68 (fitter_vpr20kmain) 0x31d188: vpr_exit_at_line + 0x75 (fitter_vpr20kmain) 0x1ba337: aa_route_lookahead_setup_cached_lookahead_constants.cold.10901 + 0x311 (fitter_vpr20kmain) 0x1aee1e: aa_route_alg_route_all_nets.cold.10872 + 0x342 (fitter_vpr20kmain) 0x2d9f4d: l_rt_prl_worker(void*) + 0xeb (fitter_vpr20kmain) 0xd6477: l_thread_start_wrapper(void*) + 0x29 (fitter_vpr20kmain) 0x40e04: msg_thread_wrapper(void* (*)(void*), void*) + 0x6e (ccl_msg) 0x11bec: mem_thread_wrapper(void* (*)(void*), void*) + 0x5c (ccl_mem) 0xc2ee: err_thread_wrapper(void* (*)(void*), void*) + 0x27 (ccl_err) 0x6cc5: thr_thread_wrapper + 0x15 (ccl_thr) 0x704e: thr_thread_begin + 0x2e (ccl_thr) 0x7fa3: start_thread + 0xf3 (pthread) 0xf94cf: clone + 0x3f (c) End-trace Executable: quartus Comment: None System Information Platform: linux64 OS name: Debian GNU/Linux OS version: 10 Quartus Prime Information Address bits: 64 Version: 19.1.0 Build: 240 Edition: Pro Edition2.1KViews0likes3CommentsInternal Error: Sub-system: VPR20KMAIN altera_arch_route_lookahead
Internal Error: Sub-system: VPR20KMAIN, File: /quartus/fitter/vpr20k/altera_arch_common/altera_arch_route_lookahead.c, Line: 4315 During the routing the Internal Error above shows up. This is consistent over several devices and every run attempted so far using Quartus 17.0 for an Arria 10 FPGA. The project did build without issue before an additional entity was added. Is there some critical point when a design is too full for Quartus to handle it? Are there any know work arounds for this issue without having to upgrade to a newer version? Upgrading the IPs in the project for a newer Quartus verison would result into other issues/a lot of work.2.3KViews0likes7Comments
