Embarking on a new FPGA design can be an exciting yet challenging journey, especially for beginners. The world of FPGAs offers immense potential for creating complex and high-performance digital systems, but it also requires a solid understanding of various design principles and tools. Whether you are a new designer or a seasoned FPGA expert, at times, you might find yourself navigating through unfamiliar territory, from understanding timing constraints to managing multiple clock domains, or in ...

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...
