Best Practice for SVA Naming Conventions Consistent SVA naming conventions not just improve code quality, but also make FV setup more easily, for example: When designers need to convert a group of assume properties to assertion properties…

Claude Code saves us tremendous effort in debugging simulation failures, like hang or data mismatch. All we did was pointing it to the test directory, TB, RTL and C-model files. Claude Code works even better with waveforms. Most simulation tools provide APIs to query signals and timing windows in wave dumps, effectively giving Claude Code more context for debugging.

We are using Claude Code extensively in debugging DV tests, and it works really well. However, it is critical to let Claude Code know where RTL, TB and C-model files locate. In our project-level CLAUDE.md, we clearly document how those files are structured to provide Claude Code some guidance, such that it won’t blindly search the entire code base every single time.

We've been using Claude Code for our real work in the past few weeks, and we found it's quite powerful for RTL Design. This post from Anthropic explains a few best practice of using Claude Code. We recommend to check it out.

Best Practices for Claude Code - Claude Code Docs Tips and patterns for getting the most out of Claude Code, from configuring your environment to scaling across parallel sessions.

Claude Code's context window is not unlimited, and the performance degrades quickly as it fills up. In our "CLAUDE.md", the 1st rule is to ask it always respond with our name. If Claude Code forgets to call "Chipress", we know it's time to start a new conversation.

In this post, we will share a few tips and tricks of writing efficient DV constraints for better simulation performance.

How to write efficient DV constraints? Split Bigger Problem into Smaller Ones Instead of mixing everything together, splitting bigger problems into smaller steps offers better performance. One may consider using “Solve-Before” for user …

Simulation hang can be caused by RTL bugs, TB issues, or C-model errors. Let's explore the hang root causes in detail.

It's not uncommon to see abort points during LEC. This post shows a few possible causes of aborts and how to debug aborts.

What are LEC abort points? How to debug aborts? It is not uncommon to see abort points during LEC. They are the key points that have not been proven either equivalent or non-equivalent based on the current tool settings, such as compare effort o…
