F4PGASlackBridge | <ept> Has anyone compared PnR times of VPR vs NextPnR for Xilinx parts? | 03:51 |
---|---|---|
F4PGASlackBridge | <ept> (If not, I may run some tests and post my findings) | 03:52 |

F4PGASlackBridge | <kgugala> there is https://github.com/chipsalliance/fpga-tool-perf doing the tests daily (it presents the results in github pages) | 07:36 |

F4PGASlackBridge | <umartinezcorral> @carlosedp SymbiFlow is now F4PGA. Do s/symbiflow/f4pga/ in the image names. | 09:50 |

F4PGASlackBridge | <umartinezcorral> @nishantpani95 AFAIAA Lattice devices are not supported/tested on F4PGA repositories yet. chipsalliance/f4pga and chipsalliance/f4pga-examples contain designs for Xilinx and Quiclogic only for now. There is some Lattice related content in f4pga-arch-defs, but I think it's not meant for end-users. | 09:58 |
F4PGASlackBridge | <umartinezcorral> https://github.com/chipsalliance/f4pga/pull/585 | 09:59 |
F4PGASlackBridge | <umartinezcorral> Nevertheless, the same tools/flow you use for ULX3S should also work for the ButterStick. I assume you are using Yosys + nextpnr-ecp5. | 10:00 |

F4PGASlackBridge | <carlosedp> My bad @umartinezcorralā¦ I should have looked at https://hdl.github.io/containers/ToolsAndImages.html ā¦ worked perfectly! | 13:57 |
F4PGASlackBridge | <carlosedp> Thanks :) | 13:57 |
F4PGASlackBridge | <umartinezcorral> https://f4pga.readthedocs.io/en/latest/development/changes.html, but I did not have time to focus on that yet. | 14:11 |
F4PGASlackBridge | <umartinezcorral> Nonetheless, we did most of the breaking changes during the last 1-2 months, so we don't expect breaks in the short future. | 14:11 |

F4PGASlackBridge | <nishantpani95> Interesting then the landing page of F4PGA should be changed to reflect that. Right now it says Lattice devices are supported | 15:19 |
F4PGASlackBridge | <carlosedp> sweet.. I need to go back testing my changes to work with Kintex7 :) | 15:34 |

F4PGASlackBridge | <ept> The runtime difference between VPR and nextpnr is striking. | 19:23 |
