| sf-slack3 | <dnhkng> Hi, im new here. I have a bit of Vivado experience for a year-long work project (all VHDL/Pynq), and was thinking about using Sybiflow for personal projects | 09:03 |
|---|---|---|
| sf-slack3 | <dnhkng> I was wondering if there are any examples of SERDES code for Series 7 or ECP5? | 09:05 |
| sf-slack3 | <dnhkng> I'm used to drag-drop IP blocks in Vivado, so I'm finding this a bit complex | 09:06 |

| sf-slack3 | <acomodi> Hi @dnhkng, in symbiflow-arch-defs there are some basic tests for SERDES you can look at and might be helpful. https://github.com/SymbiFlow/symbiflow-arch-defs/tree/master/xc/xc7/tests/serdes | 09:24 |
| tpb | Title: symbiflow-arch-defs/xc/xc7/tests/serdes at master · SymbiFlow/symbiflow-arch-defs · GitHub (at github.com) | 09:24 |
| sf-slack3 | <acomodi> Or, if you want to take a look at a more complex design that uses SERDES you can take a look to litex with DDR. https://github.com/SymbiFlow/symbiflow-arch-defs/tree/master/xc/xc7/tests/soc/litex/mini_ddr | 09:26 |
| tpb | Title: symbiflow-arch-defs/xc/xc7/tests/soc/litex/mini_ddr at master · SymbiFlow/symbiflow-arch-defs · GitHub (at github.com) | 09:26 |
| sf-slack3 | <acomodi> This last design was generated using Litex and the litedram module: https://github.com/enjoy-digital/litedram, https://github.com/enjoy-digital/litex | 09:27 |
| tpb | Title: GitHub - enjoy-digital/litex: Build your hardware, easily! (at github.com) | 09:27 |
| sf-slack3 | <dnhkng> Thanks! I'll go and explore those! | 09:27 |
| sf-slack3 | <acomodi> Forgot to mention that these are for Series 7 devices | 09:30 |

| sf-slack3 | <mholenko> @timo.callahan the magic wand TFLite demo uses an older version of litex-buildenv that doesn't come with the LiteX timer improvements out-of-the-box; In order to enable those you have to: • backport changes from https://github.com/enjoy-digital/litex/commit/be25500e9173b0e7c0ec6e8d5f626cc7f52a9484#diff-b5263d4f4c7505bfcc3542a76433f256 in LiteX • update the TFLite configuration | 13:02 |

| mithro | The design.json seem to have a new "type": "XXXX" values | 21:42 |
| mithro | andrewb1999: There seems to continue to be instability in the SDF generation | 21:43 |
| andrewb1999 | mithro: Yes, the new explicit typing was added to design.json to be able to make my work a pure superset of the roi | 21:44 |
| mithro | andrewb1999: Shall I push it to master then? | 21:45 |
| andrewb1999 | mithro: Yes, as long as you're okay with the stuff outside of design.json that has changed | 21:46 |
| andrewb1999 | mithro/litghost: I've created a python object to represent an overlay that's essentially the inverse of the roi.py in prjxray and supports cutting out multiple regions. Should I follow the current roi pattern and add this to prjxray, or should I put it in symbiflow-arch-defs? | 22:03 |
