Verification with Multi-core Parallel Simulations: Have You Found Your Sweet Spot Yet?
Resource (Paper (.PDF)) - Feb 21, 2016 Rohit Jain
This paper is aimed at verification engineers looking to improve the productivity of their verification flow and to understand where multi-core simulations can provide maximum benefit. Successful multi-core parallel simulations depend on a variety of related design factors, which can be difficult to understand and sort out. With suitable design applications, it is possible to significantly save verification cycles.

Component Configuration
Resource (Pattern) - Feb 12, 2016 Harry Foster
The Component Configuration Pattern is used to create a coherent configuration structure for the component hierarchy from top to bottom. It promotes self-containment and data-hiding techniques in the configuration and creation of component hierarchy.

Dual Domain Hierarchy Pattern
Resource (Pattern) - Feb 12, 2016 Harry Foster
The Dual Domain Hierarchy Pattern is an Environment Pattern to facilitate the design of testbenches that can be used for simulation as well as emulation, and across verification engines (or platforms) in general.

Verification Patterns - Taking Reuse to the Next Level
Resource (Paper (.PDF)) - Jan 22, 2016 Harry Foster
What is a pattern? In the process of designing something (e.g., a building, software program, or an airplane) the designer often makes numerous decisions about how to solve specific problems. If the designer can identify common factors contributing to the derived solution and abstracts the solution in such a way that it can be applied to other similar recurring problems, then the resulting generalized problem-solution pair is known as a pattern.

Precedence Chain Property
Resource (Pattern) - Dec 22, 2015 Harry Foster
The Precedence Chain Property Pattern is used to specify portions of a design model’s execution for relationships between chains (i.e., sequence of states or events1), where an occurrence of a cause chain must be have been preceded by an occurrence of an effect chain. We say that an occurrence of the effect chain is enabled by an occurrence of the cause chain.
-
Response Chain Property
Resource (Pattern) - Dec 22, 2015 Harry Foster
The Response Chain Property Pattern is used to specify portions of a design model’s execution for relationships between chains (i.e., sequence of states or events), where an occurrence of the cause chain must be followed by an occurrence of the effect chain.
-
Response Property
Resource (Pattern) - Dec 21, 2015 Harry Foster
The Response Property Pattern is used to specify portions of a design model’s execution for cause-effect relationships between a pair of states or events. An occurrence of the first, the cause, must be followed by an occurrence of the second, the effect . Also known as Follows and Leads -to.
-
Precedence Property
Resource (Pattern) - Dec 21, 2015 Harry Foster
The Precedence Property Pattern is used to specify portions of a design model’s execution for relationships between a pair of states or events,1 where the occurrence of the first is a necessary pre-condition for an occurrence of the second. We say that an occurrence of the second is enabled by an occurrence of the first.
-
Universality Property
Resource (Pattern) - Dec 21, 2015 Harry Foster
The Universality Property Pattern is used to specify portions of a design model’s verification execution that contains states or events that have a desired property. Also known as Henceforth and Always .
-
Bounded Existence Property
Resource (Pattern) - Dec 21, 2015 Harry Foster
The Bounded Existence Property Pattern is used to specify portions of a model’s verification execution that contains at most a specified number of instances of designated state transitions or events.
-
Existence Property
Resource (Pattern) - Dec 21, 2015 Harry Foster
The Existence Property Pattern is used to specify portions of a design model’s verification execution that contains an instance of a certain state or event1. Also known as Eventually or Future .
-
Absence Property
Resource (Pattern) - Dec 18, 2015 Harry Foster
The Absence Property Pattern is used to specify portions of a design model’s verification execution where a specific state or event1 should never occur. Also known Never .
-
Layering Sequence
Resource (Pattern) - Dec 18, 2015 Harry Foster
The layering sequence pattern is applicable to any situation where sequences are available that use one sequence_item but must transformed to another sequence_item to be executed on a target sequencer.
-
Utility
Resource (Pattern) - Dec 18, 2015 Harry Foster
Encapsulate small, useful functionality in a portable, easy-to-use object.
-
Façade
Resource (Pattern) - Dec 18, 2015 Harry Foster

Extending a Traditional VIP to Solve PHY Verification Challenges
Paper - Dec 10, 2015 Amit Tanwar
A comprehensive PHY verification plan must verify all of the PHY functionality in various conditions. Verification IP needs to serve hundreds of configurations and may not fit well for comprehensive PHY verification. A PCI Express Verification IP in itself covers more than 500 configurations. This creates the need of an extended version of Verification IP which completely focus on PHY related aspects.

Verification IP Stimulus APIs: Are They Really Easy to Use?
Paper - Dec 01, 2015 Amit Kumar Jain - Siemens EDA
With the increasing complexity of system designs, there is a pressing need for standalone, pre-verified, built-in verification infrastructures. Verification IP (VIP) is an integral and important component of these infrastructures for block and system-level verification as they reduce cycles spent in verifying complex designs.ly Easy to Use?
