<sb0> hartytp, when are you getting your sayma board back?
<sb0> hmm those ultrascale chips really have a lot of timing variation on global clock nets, both between P&R runs and from process variations. i think we're really going to need dynamic calibration for SYSREF_PHASE_* ...
<sb0> with different P&R runs + PVT, it can be as high as 2.3ns from the vivado data, which is pretty crazy

<sb0> not using the BUFG_GT seems to improve things, but we're still over a nanosecond

<d_n|a> sb0: Just out of curiosity, when you say a nanosecond, is that observed or predicted? Between boards? Between P&R runs?
<sb0> d_n|a, predicted
<sb0> and I'm comparing just two P&R runs

<omid> rjo, sb0: Where can I find the list of all packages versions that works with the latest phaser package? For instance what version of rustc, openocd, etc to make the package work?
