Nguyen.Dao or if you can use makefiles, see nproc.mk in openlane top directory Olof Kindgren this is a perfect example usecase for edalize-run-in-cloud | 15:54:43 |

Olof Kindgren this is a perfect example usecase for edalize-run-in-cloud I only see it runs on 1 cpu when checking the running process (openlane) | 15:55:12 |

I only see it runs on 1 cpu when checking the running process (openlane) I set ROUTING_CORES to 12 in my case but this option is for detailed routing. My flow is still stuck at Global Routing (fastrout) | 16:06:10 |

Nguyen.Dao is it still running? I’ve stopped it to change the options, now re-run it but don’t see any improve | 16:42:54 |

I’ve stopped it to change the options, now re-run it but don’t see any improve Ahmed Ghazy looks like this could be some kind of pathalogical case or infinite loop. Test case is https://github.com/FPGA-Research-Manchester/FABulous-SKY130 | 16:43:14 |

| Rob Taylor | Anyone fancy trying to implement this on top of open road? ;)

 mehdi | Hi Rob Taylor this looks interesting, are you working on this topic? | 18:43:23 |
| Rob Taylor | No, just saw it and thought it was interesting! Happy to help out if I can though | 18:44:06 |
| mehdi | I am not trying RL yet and still shooting for the low hanging fruits. So basically, trying to train a NN and predict what runs is going to be like | 18:58:32 |
| Rob Taylor | nice mehdi! | 21:08:28 |
| Rob Taylor | it’d be interesting to see if we can use the google cloud ai platform to optimise openlane runs on gke ;) | 21:11:05 |
| mehdi | I have access through Tim/Openroad and it is definitely helpful. But I still feel I am not using the gcp to its full potential. Do you have access to gcp? Maybe you could help me enhance my scripts 😉 | 21:35:21 |

| Brad B | small question: I am starting to get familiar with the OpenLNAE tools - what exactly does the acronym spm stand for? | 21:59:22 |

small question: I am starting to get familiar with the OpenLNAE tools - what exactly does the acronym spm stand for? I think I found my answer - it is one of the example designs provided in the openlane repository | 22:04:09 |

(edited) serial-parallel multiplier => serial-parallel multiplier is that it stands for, and yep it's a very-small sample design | 22:04:59 |

nice :) Update: the flow works fine with 1x2 and 2x2 CLBs fabrics without timing optimization (OpenPhySyn doesn’t support disable timing loops). For the 4x4 CLBs fabric, it’s stuck at global routing (fastroute)? | 12:54:10 |

Update: the flow works fine with 1x2 and 2x2 CLBs fabrics without timing optimization (OpenPhySyn doesn’t support disable timing loops). For the 4x4 CLBs fabric, it’s stuck at global routing (fastroute)? Does the time go up exponentially? | 13:00:55 |
| Rob Taylor | In reply to@_slack_skywater-pdk_U01GE4F371D:matrix.org
Does the time go up exponentially? Could we produce a 2x2 clb gds and then stitch together to make a bigger fabric? | 13:00:56 |
