Here are the stats for the board I am currently working on:
Overall size: 14"x23.4" with a 12.1"x6.828" component keepout in the center
Number of Nets: 2663
Number of Pins: 19331
Lines / Space: .004/.020
Number of Layers: 18 - 8 internal signal layers - pin-escapes only on outers
Number of Components: 3655
This board is GTL logic (terminating resistors)
matched length differential pairs
matched length f2's
matched length nets
matched length star topologies
daisy chained with a maximum stub length of 200mils
Board with be approximately 50% hand routed and 50% autorouted.
This board will take over 800 hours.
