| famubu[m] | Okay so himaechel is intended to be a common api for all boards? | 04:15 |
|---|---|---|
| famubu[m] | I wonder what's the meaning of himbaechel.. | 04:15 |
| Semisol[m] | https://structurae.net/en/structures/himbachel-viaduct | 04:38 |
| tpb | Title: Himbächel Viaduct (Beerfelden, 1881) | Structurae (at structurae.net) | 04:38 |
| famubu[m] | I guess I'm missing some history about that structure, but how is it relevant to nextpnr? | 04:59 |
| famubu[m] | Also, I tried using nextpnr-himbaechel and ran into something. | 05:00 |
| famubu[m] | I was trying a simple ring adder like this: | 05:00 |
| famubu[m] | https://bpa.st/FNNA | 05:00 |
| tpb | Title: View paste FNNA (at bpa.st) | 05:00 |
| famubu[m] | (I've included the yosys and nextpnr commands used as comments at the | 05:00 |
| famubu[m] | end of this paste.) | 05:00 |
| famubu[m] | I synthesised with yosys and then tried `nextpnr-himbaechel`. But that | 05:00 |
| famubu[m] | gave `No Fmax available; no interior timing paths found in design`. | 05:00 |
| famubu[m] | But upon trying nextpnr-gowin, I'm getting Max frequency for clock 'clk_IBUF_I_O': 290.53 MHz (PASS at 27.00 MHz) | 05:00 |
| famubu[m] | Why is the `nextpnr-himbaechel` command not finding Fmax? | 05:00 |
| famubu[m] | Am I using it wrong for gowin? | 05:00 |
| famubu[m] | <famubu[m]> "I guess I'm missing some history..." <- Just saw that the changelog mentions it: ' following the footsteps of Viaduct to also lower the barrier to entry to develop nextpnr support for devices' | 05:29 |
