摘要:
Hardware logic for generating breakpoint signals based on state changes in observed (“tagged”) hardware resource of a design under test is automatically generated and added to the simulation model of the design under test. These breakpoints halt simulation when a user programmable event, such as an assertion, test-case failure, or trigger occurs. Allowing the end-user to define the register values used in comparison to or timing of tagged resources, results in breakpoints that can be created, changed, enabled, or disabled without rebuilding the simulation model. Because the breakpoint logic is in-circuit, it takes full advantage of the acceleration made possible by hardware simulators, while providing an interactive environment for both functional hardware verification and software development on the simulated hardware mode.
