sf-slack | <vastarparaakshar> Hey, We almost completed our first program using symbiflow with Arty-35T boards, it’s quite working well in the hardware well, Though we are trying do a simulation using this https://symbiflow.readthedocs.io/en/latest/vtr-verilog-to-routing/doc/src/tutorials/timing_simulation/index.html but it stuck at computing wire look ahead | 10:01 |

sf-slack | <vastarparaakshar> @cjearls unless i don’t do this, slack won’t notify you . So it’s fine! | 10:01 |
sf-slack | <acomodi> Hi @vastarparaakshar, given that the lookahead and rr_graph are precomputed (also the place_delay_matrix), I think you should provide those when calling `vpr` | 10:09 |
sf-slack | <vastarparaakshar> SUre | 10:13 |
sf-slack | <vastarparaakshar> I would try that today. | 10:13 |
sf-slack | <vastarparaakshar> What value should i put in | 10:13 |
sf-slack | <vastarparaakshar> ? | 10:13 |
sf-slack | <vastarparaakshar> range. | 10:13 |
sf-slack | <vastarparaakshar> And how can we provide precomputed files to vpr maybe simple commands would help | 10:16 |
sf-slack | <acomodi> `--read_rr_graph <rr graph file> --read_placement_delay_lookup <placement delay lookup file> --read_router_lookahead <lookahead file> --router_lookahead extended_map` | 10:19 |
sf-slack | <acomodi> all the required files are in the installation package alongside with the XML | 10:20 |
sf-slack | <acomodi> If you cannot find those, you can check the VPR log files from packing, placement or routing, which display the full VPR command with all the arguments | 10:22 |
sf-slack | <vastarparaakshar> Donw. | 10:22 |
sf-slack | <vastarparaakshar> Thanks i would do that | 10:22 |
