Processor-driven tests apply universally across all phases of functional verification. They are highly portable and execute in both simulation and live-target environments. Mentor Graphics offers full functional processor models of various abstractions, which are the key to test portability. The work of firmware developers can be used to dramatically boost test coverage with minimal effort. Questa encourages the use of processor-driven tests with its integrated source-level debugger and support for multi-abstraction simulation and processor models. As embedded design complexity advances, processor-driven tests will become critical to functional verification coverage. Mentor Graphics' continued investment in HW/SW simulation technology insures that Questa is ready when you decide to make the move to processor-driven testbenches.
