How does this compare to commercial tools? I read through the original Titan-2 paper and they were 5X faster in routing but achieved worse QoR compared to Quartus - does this close the gap?<p>I'm also wondering how congested these input designs are - I don't know much about the benchmarks used. Extremely congested designs can take a much, much longer time to route so an improvement there either in runtime or QoR could be useful.
