It also employs a reference model methodology using C++ models and hardware emulation to debug designs faster than simulation alone. This methodology helps improve the schedule and find bugs earlier in the development cycle.
The document is a presentation on verification of graphics ASICs given by Shaw Yang and Gary Greenstein of AMD. The presentation covers an overview of AMD, GPU systems, 3D graphics basics including vertices, polygons, pixels and textures, verification challenges related to size and complexity, and approaches used including layered code and testbenches, hardware emulation, and functional coverage.
The document discusses the importance of using verification metrics to predict the functional closure of a CPU design project and discusses challenges in relying solely on metrics. It outlines two key types of metrics - verification test plan based metrics that track testing progress and health of the design metrics that assess bug rates and stability. Examples are provided on using bug rate data and breaking bugs down by design unit to help evaluate the progress and health of a verification effort.
The document discusses efficient verification methodology. It recommends defining a conceptual framework or methodology to standardize some aspects while allowing diversity. The methodology should define interfaces and transactions upfront using an interface definition language to generate verification components and reusable assertions. It also recommends modeling systems at the transaction level using executable specifications to frontload the verification schedule.
The document discusses the challenges of validating next generation CPUs. It notes that validation is increasingly critical for product success but requires constant innovation. Design complexity is growing exponentially, requiring up to 70% of resources for functional validation. The number of pre-silicon logic bugs found per generation has also increased significantly. Shorter timelines and cross-site development further complicate the validation process.
The document discusses validation and design in small teams with limited resources. It proposes constraining designs to a single clock rate, using FIFO interfaces between blocks, and separating algorithm from IO verification to simplify validation. This approach allows designs to be completed more quickly with fewer verification engineers through standardized, repeatable validation methods at the cost of optimal performance.
Verification challenges have increased with the globalization of chip design. Time zone differences and documentation issues can reduce efficiency, but greater collaboration across sites can also lead to new ideas. AMD addresses these challenges through a Verification Center of Expertise (COE) that coordinates methodologies across multiple sites. The COE develops tools and techniques while partnering with project teams to jointly improve processes over time through continuous review and rotation of engineers between the COE and projects.
Greg Tierney of Avid presented on their experiences using SystemC for design verification. SystemC provides hardware constructs and simulation capabilities in C++. Avid chose SystemC to enhance their existing C++ verification code and take advantage of its industry acceptance and built-in verification features. SystemC helped Avid solve issues like crossing language boundaries between HDL modules and testbenches, connecting ports and channels, implementing randomization, using multi-threaded processes, and defining module hierarchies. However, Avid also encountered issues with SystemC like slow compile/link times and limitations in its foreign language interface.
Bob Colwell documented notes from a meeting discussing the need for better software visualization tools to help localize bugs, diagnose problems, and monitor software behavior. The notes also reflect on important words in science according to Isaac Newton and reference a book about creative analogies. 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.
