Generating AMD microcode stimuli using VCS constraint solver
In this article, we explore using a hierarchical constrained-random approach to accelerate generation and reduce memory consumption, while providing optimal distribution and biasing to hit corner cases using the Synopsys VCS constraint solver. We present and analyze the method and discuss its effectiveness in today’s verification environment.

TLM-Based Verification Finds Strength In Standards
In the verification realm, new and emerging standards are behind the broadening acceptance of transaction-based verification methodologies. Standards like OSCI's TLM (transaction-level modeling) 2.0 and Accellera's Standard Co-Emulation Modeling Interface (SCE-MI) have led to a groundswell of interest in transactions. Also, flows are now using hardware acceleration and emulation to give transaction-based verification a turbo boost in speed.

Virtual Prototypes for Software-Dominated Communication Systems Designs
In a variety of application domains like wireless, multimedia, networking, and automotive, it has become more and more difficult to provide silicon solutions without the associated software executing on the hardware. Not only has software become the key functional differentiator in many areas; its development cycle now determines the overall project success.

Virtual prototyping pushes the fast forward button for software development
An introduction to how virtual prototyping takes a pair of scissors to development time and costs. Developing software for hardware prototypes that aren’t yet available has always been a complex, time-consuming task with inherent risk. The arrival of effective, easy-to-use development tools was a significant first step toward developing code faster with fewer bugs.

Attacking Constraint Complexity: Verification IP Reuse
his two-part article series looks at a scalable constraint methodology and provides an overview of some of the key constraint optimization challenges and strategies of concern to verification engineers. Part 1 of this article series focuses on verification IP reuse—detailing how a solver typically interprets constraints and providing a case study focused on a constraint-driven performance optimization strategy with respect to the flexible packet parser of a hypothetical networking ASIC.

2010 Will Change The Balance In Verification
What will 2010 bring for verification and system-level design? The semiconductor "beasts" that need to be verified are getting more and more complex. These beasts are developed at smaller technology nodes, and with the declining number of design starts. Programmability plays a significant role, both in ASIC and ASSP designs, since users have to deal with more and more processors.

Software-to-silicon verification @ 45nm and beyond
Chip and system developers once considered verification as a secondary activity following the main challenge of design, with the "Designer" playing the central role in a design's success. This notion is firmly turned on its head today, as verification is the biggest component of chip hardware development budgets, schedules, staffing and risk.
