AI Assisted Design

AI circuit design using TL-Verilog is evolving rapidly–faster than we can maintain this page, so check in with us about the latest.

TL-Verilog and Redwood tools introduce several capabilities geared toward AI-assisted circuit design:

AI is most valuable in circuit design where mechanisms exist to evaluate the resulting design quality and correctness. For logic synthesis and place-and-route, we have those mechanisms, and AI has proven valuable. TL-Verilog distinguishes behavior from implementation, with a current focus on timing abstraction. This gives AI a safe playground to make changes like logic retiming, without impacting behavior.
LLMs are valuable to assist with code conversion from Verilog/SystemVerilog, or even from other HDLs, to TL-Verilog. By incorporating formal verification with agentic flows, conversions using our open-source automation are proven correct.
Just as TL-Verilog helps humans design with a clearer and less bug-prone thought process, it helps LLMs as well. Even if it's Verilog your designers want, coding it by way of TL-Verilog might yield better results.
Redwood's technology roadmap introduces a design methodology that enables us to refactor a very complex and monolithic design process into an incremental one where tasks can be tackled in isolation. While LLMs' ability to perform monolithic tasks is limited by their context window, they perform well-defined, isolated tasks well. Engineers can focus on partitioning the problem.
With LLMs spewing TL-Verilog, the next human hurdle is understanding the spew. Reading code isn't the best way to do that. Visual Debug enables LLMs to communicate their thoughts visually, leaving us with custom visualization that accelerate development.
