"WebYes and yes. It all depends on the FPGA family's fabric, but often it's possible to bump a high-fanout net to a low-skew global resource. In some families the global clock nets really are for clocks only, meaning that they end at the flip-flops' clock inputs only. And some families have a dedicated global reset net.
