hm, synplify gets my design to 2117 LUTs and 27.7MHz, yosys/nextpnr-ice40 only to 2969 and 19.21MHz
<corecode>
hm, why?
<corecode>
maybe it optimized a quarter of my design away

nevermind, during placing it goes back up to 2974, but the clock is 28.44 now
<corecode>
i wonder if the synthesis optimized it more or the placement is the factor in it

corecode: are you passing -abc9 to synth_ice40?

nextpnr's timing is pretty conservative too, not sure if you can feed its design to synplify to analyse but you could try using icetime on both to compare?
