MLCAD26-Contest
LLM-based Algorithm Discovery for Timing Optimization
Join the exciting MLCAD 2026 Contest and showcase your innovative skills in combining agentic Large Language Model (LLM) flows with Electronic Design Automation (EDA). This year’s challenge focuses on algorithm discovery using LLMs for timing optimization.
Winners of this year’s contest will be invited to MLCAD2026 to present their solutions as a paper in the proceedings.
Contest Overview
The goal of this contest is to create a design-aware timing optimization tool. Specifically, this means you can use an LLM to update/generate/modify the EDA tool’s source code and/or internal algorithms, depending on the design to which it is applied. Contestants may begin with the baseline OpenROAD source code.
Participants may use LLMs, agentic workflows, or other methods to develop new algorithms for timing optimization and legalization on a per-design basis
Contest Challenge
- Designing a design-adaptive timing optimization algorithm that dynamically modifies strategies based on the characteristics of each design.
- Applying LLM-based or agentic optimization workflows to discover, generate, or evolve timing optimization.
- Demonstrating improved timing closure and overall design quality after placement legalization and global routing, while balancing power, routability, and runtime constraints.
Why Participate?
- Showcase your innovative solutions at MLCAD 2026. Winners will have their papers invited to the MLCAD 2026 Proceedings!
- Apply for travel grants (available for eligible participants) to MLCAD 2026.
- Winners will receive high-performance NVIDIA GPUs as prizes!
