Advanced Timing Closure Techniques for the Vivado Design Suite

FPGA 3

Achieving repeatable and reliable timing is the designer’s ultimate goal. The task of writing timing constraints and validating the design against those constraints is commonly referred to as Timing Closure. This process is essential for every design. This course will provide experienced Vivado® Design Suite users with the skills to ensure that their designs work reliably over process, voltage, and temperature variations.

You will learn the FPGA design best practices and skills to be successful using the Vivado Design Suite. This includes the necessary skills to improve design speed and reliability including: system reset design, synchronization circuits, optimum HDL coding techniques, and timing closure techniques using the Vivado Design Suite. This course encapsulates this information within the UltraFast™ Design Methodology Guide. The UltraFast Design Methodology checklist is also introduced.
