| tpb | <sf-slack> <unai.martinezcorral> With regard to Reusable Workflows and Composite Actions, I gathered some references and notes in https://github.com/pyTooling/Actions/#context. @kgugala @pzierhoffer those are the readable notes corresponding to the Actions and Workflows used in https://github.com/hdl/containers. The content pyTooling/Actions is basically a rewrite of some complex CI pipelines that we were using in some repos already (in | 01:51 |
|---|---|---|
| tpb | <sf-slack> VHDL/pyVHDLModel and EDAA). Therefore, the complete pipeline is quite opinionated. However, it is composed by more than 10 reusable workflows, so some of them might be useful in SymbiFlow/Actions. Still, we need to look at how to combine the reusable workflows with @mithro’s include processor. | 01:51 |
| tpb | <sf-slack> <unai.martinezcorral> On a different topic, I created 20+ Gource videos showing the last 5-20 years of development of ~300 repos of some open source EDA ecosystem(s): • Artifacts: https://github.com/umarcor/umarcor/actions/runs/1539507616 • Sources: https://github.com/umarcor/umarcor/tree/main/gource | 01:55 |

| tpb | <i_need_help> hello | 14:26 |
| tpb | <i_need_help> is ecp5-5g supported by symbiflow toolchain? | 14:26 |
| tpb | <zyp> yes | 14:27 |
| tpb | <i_need_help> this chip to be exact: LFE5UM5G-85F | 14:27 |
| tpb | <i_need_help> beacuse i found one of those simple boards produced by lattice and i would like to start developing | 14:28 |
| tpb | <i_need_help> how much is supported from the chip to this day? I heard that the 5g part which are some high speed tranceivers inside it were not(the things called SERDES)) | 14:30 |
| tpb | <zyp> as far as I know, all variants of ecp5 are fully supported | 14:30 |
| tpb | <zyp> and I also believe the 5G parts are just regular parts that are binned and overvolted to 1.2V | 14:31 |
| tpb | <i_need_help> i forgot to tell the world that i am a noob. is there a deb package for ubuntu that can install everything needed to start developing? | 14:32 |
| tpb | <zyp> I don't use ubuntu, so I don't have a definite answer on that one | 14:33 |
| tpb | <tnt> The serdes are supported. | 14:35 |
| tpb | <tnt> However there is no easy wizard like in diamond. You have the raw hardware block with its 100 settings or so to configure yourself and most of them are not documented because usually diamond configures them for you .. | 14:36 |
| tpb | <tnt> but if you know what you're doing, it'll generate a bitstream that works. | 14:36 |
| tpb | <zyp> I did a quick google search and couldn't find any updated PPAs with yosys and nextpnr, so you might have to build it yourself | 14:37 |
| tpb | <i_need_help> thank you for the info tnt but the idea is to not use diamond and other proprietary tools at all like the ice40 and icestudio under ubuntu.. what can be done with the chip? can you build hdmi display controllers, small 3d gpus and other things that could occupy my life till old age? | 14:37 |
| tpb | <zyp> sure | 14:38 |
| tpb | <tnt> I've been playing with the ice40 for years now and I'm still not done exploring all I want to do with it. And the ECP5 85F is like 20x larger so if you want to, it can probably provides decades of stuff to play with ... | 14:40 |
| tpb | <i_need_help> thank you zyp would be anyone on this channel skillful enough to guide me thorough the process when time needed? I mean the idea is to make the kit and put it somewere that everybody can access it so no one else will be needed to pass thorough the ordeal. I have not bought the board yet. So would i have the human support to accomplish that after | 14:44 |
| tpb | <i_need_help> the money are spent? | 14:44 |
| tpb | <tnt> There are usually people willing to answer question in here or in ##openfpga or the yosys channel ... howeve there are also times when nobody has the time to answer or nobody has any answers to what's wrong ... If you want guaranteed timely technical support you'd have to pay for it ... | 14:47 |
| tpb | <i_need_help> i am thinking of a kickstarter for something like that in the future. But in general for now the support seems to exist even if i will need to work on 3 different channels. I will buy the board in this case. Thank you for now. | 14:51 |
