Industry Trends and Business ConsiderationsProfitability
• Economy of Scale vs Performance, Development Costs– Is smaller better; smaller process
node-more devices
– One process does not fit all
– Multi-Technologies needed
– Manufacturability
“It may prove to be more economical to build large systems out of smaller
functions, which are separately packaged and interconnected. The availability of
large functions, combined with functional design and construction, should allow
the manufacturer of large systems to design and construct a considerable variety
of equipment both rapidly and economically.”
Gordon Moore

• Shrinking Device/Process Size – Advanced Nodes
• Manufacturing Advanced Nodes
• Multi-Technology Designs– Si, SiGe, SOI, InP, GaN, GaAs
– Surface Mount Devices (SMD)
– Alumina, Duroid, Flexible Substrated
• Model Support of Devices
• Multi-Technology Simulation
• Physical Effects
Some EDA Challenges
Design teams need to easily and quickly prototype designs
requiring agile editing to quickly work through design optimization
but that use manufacturable parts and processes that can be
controlled. The specification of the design and design validation
must be based on Standard’s requirements.

Smaller and smaller process nodes have unique fabrication requirements
The way we design at 7/8nm is very different than 28nm…

Virtuoso® Advanced Node
• Virtuoso® Advanced Node is the industry standard for advanced node custom/analog design
• Breakthrough release supporting novel design methodologies required at advanced nodes
• Continued partnership with leading foundries and customers to define and develop new custom design methodologies
“Through our strong collaboration and continued partnership with Cadence, we have been able to develop and deploy a
custom design methodology based on the Virtuoso Advanced-Node Platform. With our recent successful tapeout, we took
advantage of its many unique capabilities designed to manage the challenges presented at 7nm.”

• Collaborate closely with customers and foundries to define targets to build solutions/PDKs/methodologies to address this problem
Fundamental challenges designing at advanced nodes
• The reality is that as process nodes get smaller and smaller, custom layout times get longer– Project schedules are also
simultaneously being reduced
– To maintain this, the layout teams need to be larger– Hire more contractors…
– Need a better approach

Closing remarks
• Though 7nm and below presents a host of new challenges, Virtuoso® Advanced Node has been
expanded with close collaboration with foundries and early adopters to detect, prevent, and fix problems
before they occur
• Virtuoso Advanced Node has been updated to handle color-aware layout, new high-density interconnect
layers, and all new 7/8nm DRM rules
• Just the beginning — Cadence continues to proactively collaborating to define new flows, methodologies,
and functionality for an even better designer experience at 7nm and beyond
Measure early and often for first-pass success

Radio Design Flow Challenges
RF sections at one time were
sacrosanct and the designer
could count on stay-out regions.
That no longer occurs.

Like Continuous Process Improvement in manufacturing, the
EDA industry faces similar challenges and paradigm shifts.
Considerable R&D effort is expended each year for the EDA
industry to track and work with foundry advancements, device
model changes, and new Standards.
