By Cindy Eisner, Dana Fisman

This publication describes the valuables Specification Language PSL, lately standardized as IEEE general 1850-2005. PSL was once constructed to meet the subsequent necessities: effortless to profit, write, and browse; concise syntax; carefully well-defined formal semantics; expressive strength, allowing the specification for a wide category of actual global layout houses; recognized effective underlying algorithms in simulation, in addition to formal verification. simple beneficial properties are coated, in addition to complex issues reminiscent of using PSL in multiply-clocked designs. an entire bankruptcy is dedicated to universal blunders, collected in the course of the authors' decades of expertise in utilizing and instructing the language.

Example text

In the case of a clocked property, the result of a cycle-based tool will be the same as the result of an event-based tool. PSL allows the specification of a default clock, so that the clock does not have to be mentioned explicitly for each and every property. In most of this book we have assumed a singly clocked design under the cycle-based model, and thus most examples omit the explicit mention of the clock. Clocks are discussed in detail in Chapters 6 and 14. 3 Designs and traces The purpose of a PSL property is to describe the desired behavior of a design.

Another approach, used by the Optional Branching Extension (OBE), uses a tree structure that represents multiple paths. This approach is applicable only to formal verification, and is touched on very briefly in Chapter 11. 4 Current cycle, sub-traces, and modularity When a PSL property composed of two or more sub-properties is checked on a trace, it is sometimes necessary to decide the meaning of the sub-properties on a sub-trace. The current cycle is the name we give to the first cycle of a trace or a sub-trace on which we are evaluating a property or a sub-property.

PSL properties can be modified by using a clock expression to indicate that time should be measured in clock cycles of the clock expression. In the case of a clocked property, the result of a cycle-based tool will be the same as the result of an event-based tool. PSL allows the specification of a default clock, so that the clock does not have to be mentioned explicitly for each and every property. In most of this book we have assumed a singly clocked design under the cycle-based model, and thus most examples omit the explicit mention of the clock.
