Synchronous vs Asynchronous FPGA Design - Explanation and Differences

Synchronous vs Asynchronous FPGA Design

In FPGA design, there are two main approaches - synchronous and asynchronous. Understanding the differences between these two approaches is crucial for efficient FPGA implementation.

Synchronous FPGA Design

Synchronous FPGA design relies on a clock signal to synchronize the operations of different parts of the circuit. This means that all elements in the design perform their functions at specific points in time determined by the clock signal. Synchronous design is easier to implement and analyze compared to asynchronous design.

Asynchronous FPGA Design

Asynchronous FPGA design, on the other hand, does not rely on a global clock signal. Operations in asynchronous design are triggered based on the completion of previous operations, leading to a more complex and timing-sensitive design process. Asynchronous design can offer advantages in terms of power efficiency and reduced latency.
