dcarrCurious if anyone has done thinking/work on adding external IO timing constraints to nextpnr?05:30
dcarr(something along the lines of set_input_delay, set_output_delay in SDC files)05:31

dcarrtnt: Sorry, got booted off last night and didn't realize it.  Glad to hear about anyone's present thinking (if any) about IO timing constraints in nextpnr.18:56
tntI'm not sure about ECP5, but at least for ice40 those timing info haven't been extracted, so the first step would be to do that.18:59
dcarrThat makes sense.  I was digging into the ICE40 timing data and it looked to me like the "timing netlist" ended short of the actual IO pad.19:12
dcarrI haven19:13
dcarr*haven't messed with the fuzzer previously, but it seems like it could be extended to capture that19:13
dcarrtnt: Recently watched your stream from April 2020 on ICE40 IO timing.  It was really well done, thanks!19:16
