@maliberty This is a much more most recent output for CTS. Much less verbose.
Some comments on log quality and detail...

More or less the same information above repeated four times. Single line? Some of this superfluous?

Isn't LUT an implementation detail?
[WARNING CTS-0043] 560 wires are pure wire and no slew degradation.
TritonCTS forced slew degradation on these wires.
This warning is in the middle of the run and can only be found by grepping... If this is critical information, it would be easier to find at the bottom of the CTS run?

[INFO CTS-0102] Path depth 2 - 2
Hmm... Lots of information...
[WARNING STA-0357] virtual clock clock_vir can not be propagated.
The warning above is a bit drowned out and repeated many times in the logs due to the clock_vir that I have in my .sdc file.
Warning: There are 135660 unclocked register/latch pins.
What are a "unclocked register/latch" pins? There are no latches in this design.
Warning: There are 135902 unconstrained endpoints.
The .sdc file needs work...

More or less the same information above repeated four times. Single line? Some of this superfluous?
The various buffers happen to be the same here but they needn't be. The messages describe different information.
What is a "pattern" and what conclusions can the user make from this information?
Not much beyond more patterns == more runtime. It can be moved to debug.
Isn't LUT an implementation detail?
Yes, can be a debug.
There is a lot of information above... Hard to know what I should try to understand and what I can do about it...
Mostly should be debug.
What are a "unclocked register/latch" pins? There are no latches in this design.
It means registers or latch pins. Unclocked means that they have no clock signal reaching their clock pin so they will get no timing check.
What is "displacement"?
The distance an instance is moved when legalizing its location.
@maliberty @precisionmoon Is this done for now? There is still a lot of output I don't understand :-) and can't do anything about...
ChipTop now has ca. 250 lines of output. That's not an onerous task to wade through...

@maliberty Close? For my part the amount of output from CTS is reasonable. Output can always be improved everywhere, but no need for a github issue unless something is especially bad or there is a specific suggestion.
