09:42 <tnt> Anybody interested by a quickfeather ( https://shop.quicklogic.com/product/quickfeather-development-kit/ ) ? I ended up with an extra one so anyone interested can have it for the price of shipping. (Probably only make sense in EU). Read up on it beforehand because it's definitely a peculiar architecture/device and the toolchain is ... early stage.

10:28 <zyp> tnt, looks interesting

10:41 <tnt> zyp: that's one word for it :) The architecture actually looks nice. BUT (and there is quite a few), it's pretty small and slow logic. To make matter worse, yosys seems to be awful at mapping logic to it. And finally even just building the toolchain is a pain ATM.

10:42 <tnt> Hopefully that last point can be fixed ...

10:43 <tnt> The yosys mapping ... I have no idea. Yosys seems pretty fixated to the LUT architecture and although you can implement lut with the S3 LC, limiting yourself to that throws away a lot of what it can do.

10:43 <daveshah> It probably needs quite a different approach

10:44 <daveshah> abc is really optimised for good runtimes on big designs

10:44 <daveshah> QL is much better off spending more time to get a much more optimal result

10:44 <daveshah> e.g. more use of SAT might be viable

10:46 <tnt> Yeah, definitely spending more time in synth would be worth it.

11:25 <zyp> tnt, well, I certainly wouldn't mind taking the extra one off your hands

11:29 <tnt> zyp: sure, shoot me an email to 246tnt@gmail.com with your address and I'll estimate the shipping cost.
