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 V2X15:24
sf-slack2<mkurc> @mithro It seems that the V2X no longer groups instances of the same module into one pb_type15:25
sf-slack2<mkurc> @mithro For example, for the following verilog input:15:25

mithrolitghost: I like the idea behind -- could you check the implementation....17:12

litghostacomodi: 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 time18:06
litghostacomodi: That's a promising sign18:06
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
litghostacomodi: Great18:14
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:

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
mithroacomodi: So?23:03
mithroacomodi: Can you mention in that patch what the change is rather than just uploading the xls file?23:03
mithroVaughn'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 comment23:06
