04:15 <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..

04:38 <Semisol[m]> https://structurae.net/en/structures/himbachel-viaduct

04:38 <tpb> Title: Himbächel Viaduct (Beerfelden, 1881) | Structurae (at structurae.net)

04:59 <famubu[m]> I guess I'm missing some history about that structure, but how is it relevant to nextpnr?

05:00 <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?

05:29 <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'
