  • Development and debug environment in a constrained random verification
    Patent number: 9202005
    Abstract: A design verification workstation contains both debug and constraint solver capabilities during simulation of a design under test. The design verification workstation is configured to allow the user to debug constraints, stop the constraint solver, navigate problems and variables, and make modifications on-the fly during the simulation to constraint information. Additionally, in some embodiments, the design verification workstation may allow a user to use a constraint solver to experiment if the modifications will lead to desired test stimulus. Since this debug process happens during simulation, users do not need to recompile the test case. Additionally, once a user is satisfied with the modifications made to the simulation, the modification could be saved for future usage.
