RTL Pitfalls: Stop Initializing Signals, Start Testing Resets, and Use Assertions

/ Reset, RTL Code, Uncategorized, Verification /

In this article, we again explore the intricacies of register-transfer-level (RTL) coding, investigating several often-overlooked topics that frequently lead to pitfalls in design. We then discuss more general verification techniques that help identify these pitfalls, and others as soon as possible. To help connect these topics, we use the following example, which has a subtle, […]

You Can (and Should) Write Recursive RTL: Part 2

/ Recursion, RTL Code /

After the positive reception of my initial post on recursive RTL, which sparked numerous insightful discussions, I’m excited to present Part 2. In this installment, I’ll delve into addressing common misunderstandings while also introducing an optimization technique for the adder tree discussed previously. Why not create an adder tree through iterative accumulation? This question emerged

You Can (and Should) Write Recursive RTL Code

/ Recursion, RTL Code /

Recursion, a fundamental concept in both software engineering and mathematics, offers powerful problem-solving capabilities by defining a problem in terms of itself. Yet, within the realm of register-transfer level (RTL) code, its potential remains largely untapped. Despite its numerous advantages, recursion is often dismissed or deemed impossible in RTL coding circles. A simple online search
