Traditionally, FPGA design was simple. Designers set a basic clock constraint that was propagated across the chip. But now, FPGA designs have become much more complex. There are multiple clocks, and relationships between those clocks. There may be clock domain crossings that need to be accounted for. So, FPGA design tools today must feature much greater analysis capabilities to show the designer, for example, where those clock domain crossings are, to be able to constrain for multiple clocks, an...
