| Zaba | Hello. Does anybody know how to interpret an icetime report that says "Total path delay: 10000xx.xx ns (0.00 MHz)" and in which the critical path starts with loop-start, for a design with no obvious logic loops or inferred latches? | 16:21 |
| Zaba | I've posted a simple reproducer as a comment here a while back https://github.com/YosysHQ/icestorm/issues/114 (the original report seems to have a more obvious design issue leading to this) | 16:22 |
| tnt | Don't use icetime | 16:25 |
| Zaba | Is it known to be unreliable? | 16:34 |
| tnt | It's known to be broken. | 16:35 |
| tnt | nextpnr includes much better timing code | 16:35 |
| Zaba | OK that's good to know | 16:36 |
