How can I find out what the global placer is spending time on?

I need to make some sort of change to my design, because the global placement doesn't complete.

How can I get some visibility into what is going on?

[INFO GPL-0075] Routability numCall: 1 inflationIterCnt: 1 bloatIterCnt: 0
[doesn't seem to complete]

I added:

export GPL_ROUTABILITY_DRIVEN=0
export GPL_TIMING_DRIVEN=0

So now it completes... Perhaps I can glean something from this result downstream?

Yep.

The problem is that io placement falls back because there are too many pins so instead of wires going horizontally or vertically out of the macro, it is crisscrossing. I zoom in on one of those things and find a wire, then find the buffer tree and I can clearly see that IO pin placement had to fall back.

Strike that...

Mea culpa. I deleted a -group -order io constraint and pins were placed nicely so that I have a chance of vertical/horizontal wires leaving the macro :-)
