Domain-Specific Verification Method Plugs And Plays With Testbench Tools

Verification engineers need productivity if they're to tackle system-on-a-chip (SoC) functional verification. A new methodology centering on application-domain-specific verification promises a 10× to 25× productivity improvement compared with methods based on hardware description languages (HDLs).

Qualis Design's Domain Verification Component (DVC) technology addresses three critical aspects of functional verification: protocol-specific stimulus generation, automated response checking, and extraction of test-coverage metrics (see the figure).

The DVCs run as an application layer atop Synopsys' VERA and Verisity's Specman Elite testbench auto-mation tools to drastically reduce the time required to create complex verification environments for domain-specific designs. Available now within Qualis' networking family are DVCs for Sonet, ATM, Utopia 1 and 2, SPI 4.2, and Ethernet. Other networking, wireless, and core interconnect DVCs are to come.

The DVC test-stimulus generation blocks conform to industry-standard protocols and interfaces. They allow full random, constrained random, and directed test generation. Similarly, the response-checking blocks support standard protocols and interfaces to automate large regression simulation runs.

Test coverage blocks track coverage metrics by extracting coverage statistics from the environment and simulator, allowing users to accurately assess the level of test case coverage. The Qualis methodology's level-independent architecture supports advanced verification capabilities for block, ASIC/SoC, system, and board-level simulation.
