Clock Domain Crossing (CDC) Fundamentals: What Every Digital Designer Should Know

July 9, 2025July 9, 2025 vlsifacts No Comments

In today’s complex digital systems, multiple clock domains are the norm rather than the exception. Whether you’re designing an FPGA, ASIC, or SoC, it’s almost guaranteed that different parts of your chip will operate on different clocks. This creates a critical design challenge known as Clock Domain Crossing (CDC). In this first post of our CDC…

Understanding Reset Signals in Digital Design: Types, Pros & Cons, and Best Practices

June 30, 2025June 30, 2025 vlsifacts No Comments

In digital design, the reset signal is one of the most fundamental control signals. It ensures that your digital circuits start in a known, stable state before normal operation begins. Whether you’re designing a simple flip-flop or a complex processor, understanding resets is crucial for reliable and predictable behavior. In this post, we’ll explore: Why Do We…
