Managing Timing Constraints with Precision Synthesis

Managing timing constraints often seems like the painful but necessary evil of FPGA design. But "proper constraints are part of proper FPGA design," and adhering to a constraint methodology is important for implementing a design correctly. With more complex clocking schemes in today's FPGAs and the prevalence of high-speed I/O interfaces, constraint management is even more critical to system design. Without proper timing constraints, violations are not seen and the timing analysis is incomplete, potentially leading to faulty in-circuit operation that is difficult to debug.
