This publication offers formal testplanning guidance with examples considering developing assertion-based verification IP. It demonstrates a scientific technique for formal specification and formal testplanning, and likewise demonstrates powerful use of assertions languages past the normal language build discussions notice that there many books released on statement languages (such as SystemVerilog assertions and PSL). but, none of them talk about the $64000 strategy of testplanning and utilizing those languages to create verification IP. this can be the 1st e-book released in this topic

Sample text

The testbench in this example consists of a set of verification components that communicate with each other (via classes) using untimed transactions. Untimed transactions (for example, a read or a write request to a specified address) are sent to a driver transactor, whose role Chapter 3, “The Process” 43 is to convert a stream of untimed transactions into pin-level timed activity. 1 Module-based assertion IP The assertion-based monitor in our example is a modulebased transactor. Its role is to monitor the bus pin-level activity, and identify protocol violations and interesting sequences to be used for coverage.

We recommend you create a table to capture your list of properties. For each property, use a unique label identifier for each property that helps map the assertions back to the natural language properties. Step 4 Convert natural language properties into formal properties. In this step, convert each of the natural language properties into a set of SVA (or PSL) assertions or coverage properties, using any additional modeling required for describing the intended behavior. Chapter 3, “The Process” 39 Step 5 Figure 3-1 Encapsulate assertions inside a module or interface.

That tells us that A is putting transactions into the channel. B also has a thread and a transaction port, but the data flow arrow is leading into the component instead of away from it. That tells us that B is getting transactions from the channel. 5 Analysis ports Analysis ports (illustrated in Figure 2-8) are a kind of transaction-level port used for communicating analysis information (for example, coverage data or assertion error status) between components. The symbol for an analysis port is a diamond.
