1.1. Following Synchronous FPGA Design Practices

The first step in good design methodology is to understand the implications of your design practices and techniques. This section outlines the benefits of optimal synchronous design practices and the hazards involved in other approaches.

Good synchronous design practices can help you meet your design goals consistently. Problems with other design techniques can include reliance on propagation delays in a device, which can lead to race conditions, incomplete timing analysis, and possible glitches.

In a synchronous design, a clock signal triggers every event. If you ensure that all the timing requirements of the registers are met, a synchronous design behaves in a predictable and reliable manner for all process, voltage, and temperature (PVT) conditions. You can easily migrate synchronous designs to different device families or speed grades.
