capabilities
- Voltus InsightAI seamlessly integrates with the Cadence digital
full flow and system design and analysis platform for efficient
EM-IR-driven design closure
Cadence Design Systems, Inc. (Nasdaq: CDNS) today announced the
new Cadence® Voltus™ InsightAI, the industry’s first generative AI
technology that automatically identifies the root cause of EM-IR
drop violations early in the design process and selects and
implements the most efficient fixes to improve power, performance,
and area (PPA). Using Voltus InsightAI, customers can fix up to 95%
of violations prior to signoff, leading to a 2X productivity
improvement in EM-IR closure.
Power integrity is a major design challenge at advanced nodes,
with designers regularly facing a significant number of EM-IR
violations at signoff, making it imperative to address this
challenge early in the design phase. One of the major bottlenecks
of in-design EM-IR analysis is that it is computationally very
expensive due to the size and coupled nature of the power network.
The new AI-driven Voltus InsightAI helps to overcome this
bottleneck by utilizing new breakthrough machine learning methods
for very fast incremental IR analysis. Using Voltus InsightAI,
customers can use in-design analysis to enhance on-chip and chiplet
power integrity. The technology enables greater engineering
efficiency for uncovering issues early and offers key
productivity-enhancing features:
- Fast IR Inferencing Engine: The solution uses
proprietary neural networks to build models of the power grid and
can perform extremely fast incremental IR analysis to provide
instant feedback on the impact of design changes.
- IR Drop Diagnostics: Voltus InsightAI uses deep learning
to discover the root cause of IR drop problems and can quickly
identify aggressors, victims and resistance bottlenecks. It uses
electrical, spatial and timing factors for predicting IR drop
issues during design.
- Multi-Method Fixing: Decision-tree methods are utilized
to perform timing and design rule check (DRC)-aware fixes of IR
drop, using multiple methods like placement, grid reinforcement,
routing and engineering change orders (ECOs). Voltus InsightAI
selects precise fixing methods based on the root cause of the
problem, driving better utilization and improved PPA.
- Fully Integrated Solution: Voltus InsightAI is fully
integrated with Cadence’s solutions, including the Cadence Innovus™
Implementation System, the Cadence Tempus™ Timing Solution, the
Cadence Voltus IC Power Integrity Solution, and the Cadence
Pegasus™ Verification System for complete IR design closure from
implementation to signoff that is timing- and DRC-aware.
“As we move to more advanced nodes, EM-IR is quickly becoming
one of the most pressing challenges, requiring novel and innovative
approaches to address customer needs. With Voltus InsightAI,
Cadence has pioneered applying generative AI technology to EM-IR,
focusing not just on signoff, but early detection and prevention of
EM-IR violations as well,” said Ben Gu, Corporate Vice President of
R&D, Multiphysics Systems Analysis Business Unit, Cadence.
“With this capability, designers don’t need to over-design the
power grid, thereby enabling far better PPA. Customers are seeing
impressive results as they can leverage this breakthrough
technology to fix up to 95% of violations prior to signoff and
achieve more than 2X productivity improvement in EM-IR
closure.”
The generative AI-driven Voltus InsightAI supports Cadence’s
Intelligent System Design™ strategy, enabling SoC design
excellence. Customers can learn more at
