<p><span class="h-card" translate="no"><a href="https://ioc.exchange/@azonenberg" class="u-url mention">@<span>azonenberg</span></a></span> <span class="h-card" translate="no"><a href="https://chaos.social/@gsuberland" class="u-url mention">@<span>gsuberland</span></a></span> I don't really understand retiming, from an implementation perspective, enough to make any comments much less promises, but we do want at least an equivalent of `phys_opt_design` and I've been looking into how that would work</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> I don't know a lot about the internals of these synthesizers. is this along the lines of using the timing constraints early in the synthesis to make decisions about the types of blocks and their relative positions and such to meet those constraints, instead of just trying to optimise to a target after already picking the overall structure?</p>
<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> <span class="h-card" translate="no"><a href="https://chaos.social/@gsuberland" class="u-url mention">@<span>gsuberland</span></a></span> I would also love to see things like intelligent retiming that accounts for the entire flow, including things like floorplan or IO constraints that force some flops to be further away from each other (rather than trying to balance only the logic timing for each segment of the net).</p>

<p><span class="h-card" translate="no"><a href="https://chaos.social/@gsuberland" class="u-url mention">@<span>gsuberland</span></a></span> now of course the really cool bit would be "we plan to apply timing constraints at the start of synthesis, and begin using them there as well" but we haven't yet reached that point</p>
