hackerfoolitghost: I'll try to get a PR by the end of the day, but here's the branch I've been working on: https://github.com/HackerFoo/vtr-verilog-to-routing/tree/wip-testing20:58
tpbTitle: GitHub - HackerFoo/vtr-verilog-to-routing at wip-testing (at github.com)20:58
*** futarisIRCcloud has joined #symbiflow21:01
*** kraiskil has joined #symbiflow21:37
litghosthackerfoo: Is that an integrated master+wip branch?21:46
*** kraiskil has quit IRC22:01
hackerfoolitghost: Yes. I still need to rebase onto the upstream master.22:06
litghosthackerfoo: I expect you will be able to rebase nicely onto https://github.com/SymbiFlow/vtr-verilog-to-routing/tree/connection_box_serdes_merge_squashed22:07
tpbTitle: GitHub - SymbiFlow/vtr-verilog-to-routing at connection_box_serdes_merge_squashed (at github.com)22:07
hackerfoolitghost: Okay, I'll do that instead.22:08
litghosthackerfoo: What you need to do is:22:10
litghostgit rebase --onto a56cb11fbff1eadac737f4a6edce341af333c1a6 a81d5eab19f179767210096f4441f22e1a5cff32 <your branch name>22:10
litghosta56cb11fbff1eadac737f4a6edce341af333c1a6 is https://github.com/SymbiFlow/vtr-verilog-to-routing/tree/connection_box_serdes_merge_squashed22:10
tpbTitle: GitHub - SymbiFlow/vtr-verilog-to-routing at connection_box_serdes_merge_squashed (at github.com)22:10
litghosta81d5eab19f179767210096f4441f22e1a5cff32 should be the old https://github.com/SymbiFlow/vtr-verilog-to-routing/tree/connection_box_serdes_merge_squashed22:10
litghostThis is assuming your are on a feature branch on top of the old https://github.com/SymbiFlow/vtr-verilog-to-routing/tree/connection_box_serdes_merge_squashed22:10
tpbTitle: GitHub - SymbiFlow/vtr-verilog-to-routing at connection_box_serdes_merge_squashed (at github.com)22:10
litghostIf you are not, then some of what I wrote is inaccurate22:11
hackerfooI'm looking for the commit.22:16
hackerfooNo, that wasn't in my parallel-connection-box-lookahead branch yet.22:17
litghostOkay, well replace a81d5eab19f179767210096f4441f22e1a5cff32 with whatever your "root" commit on the feature branch was22:18
hackerfooI've rebased my parallel-connection-box-lookahead branch.22:48
hackerfooNow I'm going to try it out, then check it over again and submit a PR.22:49

litghosthackerfoo: What graph's have you been testing on?23:30
litghosthackerfoo: I just tested on the full 50T, and got:23:31
litghostCannot route from SYN-GND.GND[0] (RR node: 878 type: SOURCE location: (3,1) class: 0) to BLK-TL-SLICEL.BX[0] (RR node: 1922176 type: SINK location: (95,121) class: 13) -- no possible path23:31
litghostFailed to route connection from '$false' to '$auto$alumacc.cc:485:replace_alu$2737.slice[2].carry4_full' for net 'murax.system_uartCtrl.uartCtrl_1.tx.io_configFrame_stop' (#0)23:31
hackerfooThe ROI and full graph, and I've been testing murax.23:31
litghostYa, same23:32
litghostWhat is your symbiflow-arch-def githash?23:32
litghostMine is 880a06e840dc7d96d72461f2acb4fcd5e7ef580c merged with c427fe0b4645560df51160881d3cde84725e7dd5 (e.g. master)23:32
litghostI was testing with VTR @ 0477b874ad1be65626c99ae13f707586a7dae11623:33
hackerfooarch-defs @ 5d68d4e8e82a3d36d6b9fb26d95038105afc567923:35
hackerfooWith this patch: https://gist.github.com/HackerFoo/76989afd10f4f75d10226c91e90814d923:35
tpbTitle: remove-graph-limit.diff ยท GitHub (at gist.github.com)23:35
litghostRight, I was about to ask about that23:36
litghost5d68d4e8e82a3d36d6b9fb26d95038105afc5679 doesn't have the graph limit removed23:36
hackerfoobuilding murax_basys_x1y0_fasm23:36
litghostSame target on my side, that produced the above error23:37
litghostHow many sample points did your code have?23:37
hackerfooI'm working on the octopus merge right now, so I haven't run the new branch yet.23:38
hackerfoo3x323:38
litghostgrep "Expanded sample" xc7/archs/artix7/devices/vpr_stdout.log | wc23:38
litghost    476    3808   2721623:38
litghostok23:38
hackerfooIt sorts the points by the index of the first point to hopefully be more cache friendly.23:39
hackerfooAt least, there's no reason to group the expansion per segment type anymore.23:40
hackerfooEach `SamplePoint` is a group of the same segment type, though.23:41
hackerfooSo it should be 3 * 3 * segment types * connection box types, roughly.23:42
