| nickoe | Does symbiflow (prjxray) support xc7a35t-csg324-1? | 15:33 |
|---|---|---|
| sf-slack | <kgugala> yes, this is the part used on Arty | 15:34 |
| sf-slack | <kgugala> we have quite a few examples targeting this boards | 15:34 |
| sf-slack | <kgugala> *board | 15:34 |
| nickoe | Ok, it was just because I tried to build wtih the symbiflow toolchain in litex and in litex there is a mapping where this is not part of | 15:36 |
| nickoe | let me find it again | 15:36 |
| nickoe | kgugala https://github.com/enjoy-digital/litex/blob/321b91d551ae58f32c14596985d096d178c32be6/litex/build/xilinx/symbiflow.py#L109-L113 | 15:41 |
| nickoe | And also the sxection fuirther down? https://github.com/enjoy-digital/litex/blob/321b91d551ae58f32c14596985d096d178c32be6/litex/build/xilinx/symbiflow.py#L127-L131 | 15:42 |
| sf-slack | <kgugala> xc35t and xc50t are the same chips | 15:42 |
| nickoe | Currently I have defined the chip in my platform description as "xc7a35t-csg324-1" | 15:43 |
| nickoe | And I am not really too familiar with the naming to really understand if somthing is compatible synbiflow wise or otherwise .. | 15:44 |
| nickoe | Should I just add "xc7a35t-csg324-1" : "xc7a50t_test", to the dict for symbiflow-device? | 15:46 |
| sf-slack | <kgugala> yep, you can | 15:46 |
| sf-slack | <kgugala> or simply use xc7a35ticsg324-1L | 15:46 |
| nickoe | does the i vs dash mean anything, and the L? | 15:48 |

| sf-slack | <kgugala> check this https://www.xilinx.com/support/documentation/selection-guides/7-series-product-selection-guide.pdf (slide 6) | 15:58 |
| nickoe | Ohh, well, ERROR: Cell port mars_ax3.BbFilterAXI.o_tvalid is driving constant bits: 1'0 <= \BbFilterAXI.o_tvalid still some way to go for symbiflow, but I gues I need to re-fixup the build with vivado ebfore I try to compare with symbiflow again. At least I can easily test it now. | 15:59 |
| nickoe | kgugala thank you for the link | 16:00 |
| nickoe | I made this workaround for now, https://github.com/nickoe/litex-boards/commit/473a748c24776ceca1dff4e57a54d5ae1798c4e5 | 16:00 |
