|Achieving ISO 26262 Software Tool Confidence for Improved Automotive Functional Safety|
Achieving ISO 26262 Software Tool Confidence for Improved Automotive Functional Safety The rapid adoption of advanced electronic systems in automobiles has prompted the automotive industry to develop the ISO 26262 functional safety standard to address the potential risks associated with failures in these systems. ISO 26262 is derived from the more general IEC 61508 standard and defines requirements for the design and test processes of electrical and electronics (EE)-based automotive safety-related systems. Although the standard applies to hardware and software elements of these systems, this paper discusses only the hardware elements — more specifically, the design flow and related EDA tool confidence evaluation process related to the implementation of digital and analog/mixed-signal (AMS) integrated circuits (ICs).

|Advanced Dynamic Power Reduction Techniques: XOR Self Gating|
A common technique for saving dynamic power is to insert clock gates. Clock gates are elements that control the arrival of clock signals to sequential elements. If a condition can be found in which the sequential element does not need to load data, then power can be saved by blocking the clock signal. This can be performed via XOR self-gating, an effective technique for reducing dynamic power consumption.

|Testing Low Power Designs with Power Aware Test|
The most important trend over the past decade for semiconductor design is the dominant requirement to reduce power consumption and power dissipation. Not only do competitive products require more functionality and higher performance, they must fit into increasingly smaller and more portable products.

|Synthesis-Based Test For Maximum RTL Designer Productivity|
Exponential growth in size and complexity of systems on a chip (SoCs), coupled with increasingly
stringent quality mandates, necessitates an efficient and productive approach for register-transferlevel
(RTL) designers implementing design-for-testability (DFT). Synopsys provides test technology
embedded in synthesis, or “synthesis-based test”, to implement the key aspects of DFT for scan testing,
boundary scan, embedded memory test, on-chip testing of high-speed blocks like USB and PCI Express®
cores and connections to yield analysis.
|Techniques for Achieving Higher Completion in Formality®|
Formality is an equivalence-checking solution that uses formal, static techniques to determine if two versions of a design are functionally equivalent. Formality delivers superior completion on designs compiled with DC Ultra.

|Using TetraMAX® Physical Diagnostics for Advanced Yield Analysis|
Scan-based DFT is now the standard digital logic testing used on almost all SoC designs.

|Multicore and Distributed Processing With TetraMAX® ATPG|
Running automatic test pattern generation (ATPG) on a single processor may take a week or longer to complete, especially for very large designs and when testing at-speed fault models. Designers and test engineers need a straightforward way to reduce ATPG runtime by many factors and deliver working test patterns in days, not weeks.

|DC Ultra Accelerating Design Closure|
A predictable RTL to GDSII design flow is esential for the completing designs on time. Synopsys' DC Ultra(TM) topographical technology accurately prdeicts layout results, such as timing, area, and power during synthesis, and delvers a predictalbe RTL-to GDSII implementation flow.
|DFTMAX Compression Backgrounder|
Scan design, the ubiquitous design-for-test technology, is based on a relatively simple concept: One or
more scan chains are constructed on a chip by serially tying together a set of internal registers and flip-flops.
