Finally, they caution against agreeing to sign a document just because a product is shipping.
The document outlines the verification strategy for a PCI-Express presenter device. It discusses the PCI-Express protocol overview including terminology, hierarchy and functions at various layers. It emphasizes the importance of design-for-verification using techniques like modular architectures, standardized interfaces and reference models to aid in functional verification closure and compliance testing. Performance verification is also highlighted as critical given the real-time requirements of the standard.
The document discusses verification strategies for PCI-Express. It outlines the PCI-Express protocol and highlights challenges in verifying chips that implement open standards. The verification paradigm focuses on functionality, performance, interoperability, reusability, scalability, and comprehensiveness using techniques like constrained-random testing, assertions, reference models, emulation, and compliance checkers. The goal is to deliver compliant and high-performing chips with zero bugs through an effective verification methodology.
The document discusses methodologies for improving verification efficiency at Cisco. It advocates separating testbench creation into three stages: component design, testbench integration, and testcase creation. It also recommends using standardized methodologies like testflow to synchronize component behavior, reusing unit-level component models and checkers, linking transactions between checkers, and generating common testbench infrastructure from templates to reduce duplication of effort. The key is pushing reusable behavior into components and standardizing common elements to maximize efficiency.
This document discusses the importance of pre-silicon verification for post-silicon validation. It notes that post-silicon validation schedules are growing due to increasing design complexity, while pre-silicon verification investment and methodologies have not kept pace. The document highlights mixed-signal verification, power-on/reset verification, and design-for-testability verification as key focus areas needed to improve pre-silicon verification and enable faster post-silicon validation. It provides examples of mixed-signal and power-on bugs that were found post-silicon due to insufficient pre-silicon verification of these areas. The document argues that pre-silicon verification must move beyond just functional verification and own mixed-signal effects
This document discusses challenges in low-power design and verification. It addresses why low-power is now a priority given trends in mobile applications. Key challenges include increased leakage due to process scaling, accounting for active leakage, and handling process variations. The document also discusses low-power design methodologies, including multiple power domains, voltage scaling, and clock gating. Verification challenges are presented, such as needing good test patterns and coordination across design domains. Overall power analysis is more complex than timing analysis due to its pattern dependence and need to optimize for performance per watt.
Verilog-AMS allows for mixed-signal modeling and simulation in a single language. It provides benefits like simplified mixed-signal modeling, decreased simulation time, and improved mixed-signal verification. Previous solutions involved using two simulators or approximating analog circuits, which caused issues like slow simulation and lack of analog results. Verilog-AMS uses constructs from Verilog and Verilog-A to model both analog and digital content together. This avoids issues with interface elements between domains.
This document discusses the verification of Intel's Atom processor. It describes the key verification challenges, methodology used, and results. The main challenges were verifying a new microarchitecture with aggressive schedules and limited resources. The methodology involved cluster-level validation, functional coverage, architectural validation, and formal verification. Metrics like coverage, bug rates, and a "health of model" indicator were used. The results showed a successful pre-silicon verification with few escapes and debug/survivability features working as intended. Key learnings included the importance of keeping the full-chip design healthy early and putting equal focus on testability features.
The document discusses verification strategies based on Sun Tzu's classic book "The Art of War". Some key points:
1. Sun Tzu emphasized understanding the objective conditions and subjective opinions of competitors to determine strategic positioning. This relates to verification where it is important to understand the design and "Murphy the Designer".
2. Sun Tzu's 13 chapters provide guidance on tactics like laying plans, attacking weaknesses, maneuvering, and using intelligence sources. These lessons can help verification engineers successfully navigate different stages of a competitive campaign against bugs and errors.
3. Effective verification requires knowing the design, understanding one's own verification process, preparing appropriate tools, and using feedback to improve. Coverage metrics alone do
Here are the key challenges faced in low power design without a common power format:
1. Domain definitions, level shifters, isolation cells, and other low power techniques are specified differently in each tool using tool-specific commands files and languages. This makes cross-tool consistency and validation difficult.
2. Power functionality cannot be easily verified at the RTL level without changing the RTL code, since power domains and low power techniques are not represented. This limits verification coverage.
3. Iteration between design creation and verification is difficult, since changes to the low power implementation require updates to multiple tool-specific specification files rather than a single cross-tool definition. This impacts design schedule and risks inconsistencies.

This document discusses various metrics used to measure the progress and health of CPU verification. It describes architectural verification to ensure implementation meets specifications, as well as unit architecture and system level verification. Key metrics include pass rates for legacy tests, functional coverage, bug rates, lines of code changes, and a health of the model score to measure convergence. Secondary metrics like cycles run, bugs found at different levels, and test bench quality are also outlined.
This document discusses Freescale's verification of the QorIQ communication platform containing the CoreNet fabric using SystemVerilog. It describes the verification challenges, methodology used, and verification IP developed. Key aspects included developing a SystemVerilog testbench, CoreNet VIP, and hierarchical verification. This approach successfully verified the CoreNet platform and resulted in first silicon sampling to customers within 3 weeks with no major functional bugs found.
The document discusses verification challenges for modern wireless system-on-chips (SoCs). It describes how SoCs now include multiple processors, modems, multimedia components, and peripherals, making verification much more complex. Traditional "golden vector" verification is insufficient, as it lacks reactivity, coverage metrics, and visibility into hardware-software interactions. The document advocates for model-based verification using system models, constraints, assertions and other techniques to achieve a higher level of integration and achieve full functional coverage. This modern approach allows testing across different levels of abstraction and integration.
This document discusses power domain verification for the AeroFONE® product. It has multiple power domains for power savings and isolation. Static and dynamic verification is used. Static checks include ensuring all inputs and outputs are defined when changing power states. Dynamic verification exercises all power up sequences and mode transitions. Interface cells between domains are modeled in Verilog-AMS to represent the electrical behavior. Voltage regulators and their control loops are also modeled. The goal is to efficiently model the effects of different power configurations and combinations.
The document discusses the verification of the QorIQ Communication Platform containing the CoreNet Fabric using SystemVerilog. It describes the QorIQ platform as an SoC processor containing single, dual, and many cores that offers high performance, power efficiency, and programmability. Specifically, it highlights the QorIQ P4080 processor, which integrates eight Power Architecture cores, a tri-level cache hierarchy, and an innovative CoreNet fabric and data path acceleration. The presentation will focus on the verification challenges and solutions in verifying the CoreNet platform using SystemVerilog.
