| dcarr | tnt: 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 |
| tnt | I'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 |
| dcarr | That 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 |
| dcarr | I haven | 19:13 |
| dcarr | *haven't messed with the fuzzer previously, but it seems like it could be extended to capture that | 19:13 |
| dcarr | tnt: Recently watched your stream from April 2020 on ICE40 IO timing. It was really well done, thanks! | 19:16 |
