Smarter ECOs: Inside Easy-Logic’s ASIC Optimization Engine

Easy-Logic Technology Ltd. is a specialized Electronic Design Automation (EDA) company focused on solving one of the most complex and time-sensitive challenges in semiconductor design: functional Engineering Change Orders (ECOs). Founded in 2014 and headquartered in Hong Kong, the company has built its reputation around advanced logic optimization algorithms that help ASIC and SoC design teams implement late-stage design changes quickly and safely.

In modern chip development, errors or specification changes often surface late in the design cycle, sometimes after synthesis, place-and-route, or even physical layout. At that stage, making changes manually can be extremely risky and costly. A single modification may ripple through large portions of the logic, potentially affecting timing, testability, or power consumption. Traditionally, engineering teams would rely on manual patching or partial redesign, which can extend schedules and increase the chance of introducing new bugs.

Easy-Logic’s core focus is automating this ECO process. Its flagship solution, commonly referred to as EasylogicECO, provides functional ECO automation that generates optimized logic patches directly from specification changes or RTL updates. Instead of requiring a full re-synthesis or broad structural modifications, the tool computes minimal patch logic that satisfies the new functionality while preserving as much of the existing netlist as possible. This significantly reduces disruption to timing closure and layout integrity.

One of the key strengths of Easy-Logic’s approach lies in its algorithmic foundation. The company was founded by researchers and engineers with strong academic backgrounds in logic synthesis, formal methods, and verification. By combining formal equivalence techniques with optimization strategies, the tool can identify the smallest set of logic changes needed to meet new design requirements. This minimizes area overhead and maintains design stability, critical factors in advanced process nodes where margins are tight.

Another important area of capability is post-layout ECO support. In late tape-out stages, designers often prefer “metal-only” ECOs, where changes are implemented by modifying metal layers without altering lower layers of the silicon. This approach reduces manufacturing costs and avoids restarting expensive mask processes. Easy-Logic’s solutions are designed to support these constraints, enabling functional updates while preserving physical design structures. This makes the tool particularly valuable for high-volume ASIC programs with strict deadlines.

Scan chain repair and DFT preservation are also integrated into the ECO flow. Functional modifications can disrupt scan connectivity, which is essential for manufacturing test coverage. Easy-Logic addresses this by automatically repairing or maintaining scan chains after logic patches are applied. This ensures that testability remains intact without requiring separate manual correction steps.

Within the broader EDA industry, Easy-Logic occupies a focused niche. The global EDA market is dominated by large vendors offering end-to-end tool suites covering synthesis, verification, simulation, and physical implementation. Rather than competing directly across all categories, Easy-Logic concentrates on the functional ECO segment. This specialization allows it to deliver deep technical solutions in an area that is critical but often underserved by broader platforms.

The company’s tools are used by semiconductor firms developing complex ASICs for consumer electronics, networking, artificial intelligence accelerators, and industrial applications. As chip complexity increases with billions of transistors integrated into advanced nodes the likelihood of late-stage design changes grows. ECO automation therefore becomes increasingly important for meeting aggressive time-to-market targets.

Beyond time savings, Easy-Logic’s solutions contribute to risk reduction. Late design changes are inherently dangerous because they can unintentionally impact previously verified functionality. Automated formal verification embedded within the ECO flow helps ensure that only the intended modifications are introduced. This reduces the probability of silicon re-spins, which can cost millions of dollars and months of delay.

Bottom line: Easy-Logic Technology Ltd. represents a highly specialized player within the semiconductor software ecosystem. By focusing on functional ECO automation, it addresses a bottleneck that directly affects schedule, cost, and design stability. As semiconductor projects continue to grow in complexity and competitive pressure increases, the ability to implement safe, minimal, and efficient late-stage logic changes will remain a critical advantage and that is precisely the domain in which Easy-Logic has built its expertise.
