|Accelerated Optimization with IC Compiler II |
Efficient optimization is a necessary yet challenging aspect of the physical implementation flow. Newer nodes and growing designs are all conspiring to place growing demands on this already difficult area of efficient IC design. IC Compiler II and the underlying physical optimization engines have been re-thought and re-architected to address these growing challenges and to set the stage for the future.

|IC Compiler II: Building a Scalable Platform to Enable the Next 10x in Physical Design |
Keeping up with the pace demanded by Moore’s law is putting increasingly expanding strains on today’s design planning and physical implementation tools. Merely tweaking existing solutions will not provide a path to handle the complex designs that we are quickly moving towards. IC Compiler II’s development has embraced the opportunity to rethink the implementation and data management paradigm to deliver on leading capacity and throughput.

|Fast, Convergent Clock Synthesis & Optimization with IC Compiler II |
As more and more challenges from capacity, variability and complexity need to be managed, it is imperative to readdress and rethink both the algorithmic and infrastructural aspects of clock implementation. IC Compiler II has been architected with all of these challenges in mind and delivers a clocking solution with a breadth of technologies to meet the needs of today’s and tomorrow’s clock design challenges.

|Advanced Design Planning in IC Compiler II|
Design exploration and planning is becoming an increasingly critical step of the design creation process as growing constraints and requirements are placed upon it. IC Compiler II has been architected from the ground up with the express focus to address the three key challenges of design planning.

|Realizing Advanced P&R Design Utilizing Established Process Nodes|
Despite the high mindshare garnered by the latest developments at 16nm and 10nm, the fact is that the majority of designs taped out today are at 45nm and above. It is clearly the time to disassociate the term "advanced" from "technology node". Advanced designs are occurring at both established process nodes and at emerging process nodes. Today, advanced design should be considered process node independent. This paper takes an i-ndepth look at advanced place and route design using established process nodes.

|Accelerating 20nm Double Patterning Verification |
This whitepaper presents the key concepts of DPT compliant design and demonstrates how new signoff technology in IC Validator makes it possible to ensure 20nm manufacturing compliance. Recognizing that the designer productivity necessary cannot be achieved alone by point-tool enhancements and post-processing techniques, the paper outlines advances in In-Design physical verification within IC Compiler.

|Physical Verification of FinFETs and Fully Depleted SOI|
It has come to be broadly accepted in the semiconductor industry that short-channel effects severely limit bulk planar transistor performance, and alternative device structures will necessarily have to be adopted if we are to shrink process geometries below 20nm. This paper explores the two major contenders for the new transistor architecture: finFETs and fully depleted silicon-on-insulator.

|Multi-Source CTS Delivers Flexible High Performance and Variation Tolerance|
Multi-Source CTS delivers the ideal hybrid solution for designers seeking the best of conventional CTS and pure clock mesh. IC Compiler Multi-Source CTS provides better high-speed performance and OCV tolerance than conventional CTS and is more tolerant of complex floorplans and provides more flexibility for clock gating depth than pure clock mesh.

|IC Validator: Physical Verification for Analog Designs|
Physical verification challenges of analog designs are different than the challenges of large digital designs. In addition to complex runset requirements, a tight interface to a parasitic extraction tool and an easy-to-use GUI are needed to use a runset effectively in an analog design environment. IC Validator, the latest generation physical verification tool, can be used to solve these issues. This paper addresses many of the physical verification requirements of analog designers and how they are met with IC Validator.

|Physical Datapath - Improved Productivity for All Designs |
Currently, most EDA tools do not provide a solution that addresses the limitations of a custom datapath flow. This paper discusses datapath designs, benefits, limitations, and the use of an automated datapath design capability that allows both custom and ASIC designers to meet aggressive design objectives with ever-tighter project deadlines.

|Multicorner-Multimode – A Necessary and Manageable Reality of Design |
Resolving correlation issues is a time consuming step and is all the more challenging when it has to be done across multiple corners and modes. Tight correlation to signoff is critical for faster time to results. d d

|IC Validator: GDS Merge|
With today’s increasingly complicated design flows, creating a snapshot of a design’s full mask set to run physical verification at intermediate points during the design cycle, or in-design, presents many challenges. This paper presents an optimal approach to creating a working snapshot of a design’s complete mask data set for the purposes of in-design physical verification with IC Validator, Synopsys’ award-winning physical verification platform for advanced nodes.

|IC Validator: Automatic DRC Repair|
This paper presents how in-design physical verification with IC
Validator enables Automatic DRC Repair (ADR), a novel capability that makes it possible for designers to
automatically detect, repair and revalidate signoff DRC violations with negligible physical or timing impact, all within IC Compiler.

|Realizing Low Power IC Design: It Starts with the Clock Tree|
There are numerous techniques to achieve a low-power design and several approaches to structuring the flow. As a starting point, high performance designs require a benchmark proven low-skew, low-insertion delay CTS solution. Correlation to industry standard sign-off engines for accuracy and minimum data format translations are required to achieve fast design closure. The optimal solution includes complete low power capability throughout the design flow. This paper addresses low power design issues and includes technologies and techniques to achieve high performance, low power design goals.

|Advanced Design Challenges Make DFM-Friendly Routing A Must-Have |
Timing, area, power, and signal integrity have traditionally been the primary objectives of design technology, and the primary care-abouts for designers and CAD engineers. Increasingly manufacturability and yield have also become critical design objectives, and multiple design-for-manufacturability (DFM) optimization techniques have been added to the design flows. As manufacturability has been a secondary goal, conventional routers have been optimizing for it after timing optimization – the point at which all of the primary design goals have already been met. While this methodology has worked well up to the 65nm technology node, it starts to break down at 45nm and below. This paper talks about the routing challenges at 45nm and below and the need for modern DFM-friendly routing technologies for achieving better manufacturability and higher yield without sacrificing performance.

|Accelerating Physical Verification with an In-Design Flow|
There is a growing need for a concurrent physical design and physical verification flow, also known as an in-design physical verification flow. This flow improves the overall turnaround time and ease of use of the physical verification process. This paper provides a production-proven example of this flow.
|Clock Mesh for Mainstream Designs|
By its very nature, even the best conventional clock tree synthesis leaves both performance and variation tolerance potential on the table. Clock mesh offers the designer a means of achieving extreme high performance along with the avoidance of process variation effects. Long known as the clock distribution method for high-end microprocessors, clock mesh also offers significant variation tolerance. Clock mesh use to be an entirely manual, difficult to analyze technology, but new advances in clock mesh automation and analysis now enable it to be considered as a mainstream clock distribution solution.
