| sf-slack2 | <acomodi> I think I finally found a way to let the mode selection work without increasing the original pack time. | 14:58 |
|---|---|---|
| sf-slack2 | <acomodi> Basically now different mode selection is activated only when there is no possible route while expanding nodes in `try_intra_lb_route` | 14:59 |

| sf-slack2 | <mkurc> Good time of day! | 15:24 |
| sf-slack2 | <mkurc> @mitrho I started merging my code related to FASM support in V2X | 15:24 |
| sf-slack2 | <mkurc> @mithro It seems that the V2X no longer groups instances of the same module into one pb_type | 15:25 |
| sf-slack2 | <mkurc> @mithro For example, for the following verilog input: | 15:25 |
| sf-slack2 | <mkurc> @mithro https://pastebin.com/sVAHNCDY | 15:26 |
| tpb | Title: [VeriLog] `include "../common/and_gate/and_gate.sim.v" `include "../common/xor_gate/xor_g - Pastebin.com (at pastebin.com) | 15:26 |
| sf-slack2 | <mkurc> @mithro I have: | 15:26 |
| sf-slack2 | <mkurc> @mitrho: https://pastebin.com/sEZGk8vQ | 15:27 |
| tpb | Title: [XML] (at pastebin.com) | 15:27 |
| sf-slack2 | <mkurc> @mithro Those four gates are of the same type and should be grouped into one <pb_type> tag with num_pb = 4 | 15:27 |

| mithro | litghost: I like the idea behind https://github.com/SymbiFlow/prjxray/pull/842 -- could you check the implementation.... | 17:12 |

| litghost | acomodi: Sounds good, do you have data to support the increased performance? | 18:03 |
| sf-slack2 | <acomodi> litghost: I am running again the VTR benchmarks, they should complete in about an hour. I have checked the run-time difference on a test that took ~10% more than master and now it takes almost the same time | 18:06 |
| litghost | acomodi: That's a promising sign | 18:06 |
| sf-slack2 | <acomodi> litghost: Yes, I think this is the best we can get, once the first batch completes I'll run the Titan benchmarks. I believe after I get those the PR will get merged. | 18:14 |
| litghost | acomodi: Great | 18:14 |
| sf-slack2 | <acomodi> litghost: packing time is even less now w.r.t master. The whole VTR flow still takes ~0.8% time more w.r.t. master. If interested the comparison is here: https://github.com/verilog-to-routing/vtr-verilog-to-routing/pull/517#issuecomment-494104583 | 18:52 |

| mithro | @acomodi: I don't quite understand your qor stuff on #517? | 22:54 |
| mithro | @acomodi: It seems like packing time has gone up by either 4-5% or 10%? which is it? | 22:55 |
| sf-slack2 | <acomodi> mithro: that was before the changes I have committed today. Right now we have a no increase in packing time. | 23:02 |
| mithro | acomodi: So? | 23:03 |
| mithro | acomodi: Can you mention in that patch what the change is rather than just uploading the xls file? | 23:03 |
| mithro | Vaughn's latest comment was "The +10% pack time is a pain, but otherwise everthing looks good. " | 23:04 |
| sf-slack2 | <acomodi> mithro: Sure, I'll update the comment | 23:06 |
