I can only imagine how long it will take the fitter to pnr these insanely wide busses. Maybe a 13th gen CPU overclocked to 8GHz would be handy.

Xilinx keeps advertising the bejeesus out of their AI p&r, but I haven't touched these tools in years -- how much do the claims translate to reality?

Considering my experience with Xilinx, the more they advertise it the harder it sucks.

Xilinx design tools are some of the buggiest pieces of software known to humankind. Altera(Intel) not far behind.

This applies to basically all electronics design tools. Insanely expensive ($5-100k per seat per year is common) and insanely buggy.

Altium, considered one of the best PCB cad tools, hard crashes for me every hour or two of design work I do.

Days at least. P&R is NP hard I believe. Force directed placement or simulated annealing is slow and random :/
