Accelerating Design Closure with Cadence Certus Closure Solution v25.1

For design engineers working at the bleeding edge of semiconductor innovation, timing closure is often the most time-consuming and resource-intensive phase of the design cycle. With increasing design complexity, tighter power budgets, and shrinking time-to-market windows, traditional signoff flows-often requiring five to seven days per iteration-are no longer sustainable.

The Cadence Certus Closure Solution is engineered to solve this exact pain point. Whether you are tackling hierarchical designs or navigating the complexities of 3D-IC architectures, the Cadence Certus Closure Solution delivers overnight concurrent full-chip optimization and signoff, leveraging a massively parallel and distributed architecture. This blog explores what makes the Cadence Certus Closure Solution unique, and how Cadence's training programs equip engineers to harness its full potential.

Key Features and Benefits

• Distributed ECO (Engineering Change Order) implementation across partitions
• Client-server architecture with Certus Manager orchestrating Tempus and Innovus clients
• Incremental routing and parasitic extraction within the same session
• SmartMMMC (Multi-Mode Multi-Corner) analysis with over 200 views
• Empowered Collaboration: Eliminates iterative loops between block owners, enabling rapid decision-making

Real-World Impact: From Days to Hours

Consider a 6nm design project involving 22 million instances across 11 blocks. Using conventional flows, timing and power closure would typically take several days per iteration. With the Cadence Certus Closure Solution, the team achieved closure in just 11 hours, recovering 99% of setup violations and 97% of hold violations—all while reducing total power consumption by nearly 3%.
