| tpb | <Yura> Hey folks , really happy to discover this community and want to contribute a bit . For now unfortunately i'm a bit stuck with basic tools stuff . Can some one advice on good starting tutorial ? (I have background with HW, logic and a little bit of SW ) | 09:17 |
|---|---|---|
| tpb | <nimh> Hi Yura, I just got started too. Do you have any of the devel boards? | 09:39 |
| tpb | <nimh> ah - missed them... | 09:40 |
| tpb | <bl0x_> Question: what's the general status/interest of supporting older xilinx devices such as Spartan 6 with the open toolchain? Symbiotic EDA mentions experimental support in their web page, but no details. | 11:21 |
| tpb | <bl0x_> Is there a project similar to prjxray that is not easily discoverable? | 11:22 |
| tpb | <marzoul> bl0x_ : it should be relatively straightforward to add spartan6, given that the first spartan7 chip was just added recently. You could look into the commit and try adapting it to spartan6 perhaps | 11:58 |
| tpb | <marzoul> except... is spartan6 sill supported by vivado2017.2 ? Because the DB generation scripts are locked to that version for technical reasons | 11:59 |
| tpb | <nimh> when I'm trying to create model.xml and pb_type.xml is this the right thing to do: | 12:00 |
| tpb | <nimh> <pb_type name="DSP48E1" blif_model=".subckt DSP48E1_VPR" num_pb="1"> | 12:00 |
| tpb | <nimh> <model name="DSP48E1_VPR"> | 12:01 |
| tpb | <cr1901> Spartan 6 is mostly ISE | 12:01 |
| tpb | <nimh> the pb_type .subckt is the model name in model.xml? | 12:01 |
| tpb | <cr1901> bl0x_: Spartan 3 and 6 are being done by someone (not me). It's not a public project, but I know someone is working on it | 12:01 |
| tpb | <cr1901> Sorry that my source is "just trust me" :P | 12:01 |
| tpb | <tnt> mostly ? It's only ISE AFAIK. | 12:02 |
| tpb | <cr1901> There's some weird Windows 10-only version of Vivado for S6 devices | 12:04 |
| tpb | <cr1901> And _only_ S6 devices ._. | 12:04 |
| tpb | <tnt> ?!? Got a link to that, I've never seen it. | 12:06 |
| tpb | <cr1901> Oh... it doesn't exist. Because it's ISE... whoops :D https://www.xilinx.com/support/documentation/sw_manuals/xilinx14_7/ug1227-spartan6-vm-windows10.pdf | 12:07 |
| tpb | <nimh> also, I see there are fasm_params, and they look like they map to synthesis attributes, but where do I find which fasm_params exist? | 12:13 |
| tpb | <bl0x_> cr1901: thanks, that means any effort spent on it would be doubled at the moment. Is there a chance the project will be made public in the future? I take it there are commercial reasons to keep it closed for now? | 15:09 |
