VGS Issues and Guidelines

From T-VEC Wiki

Test Vector Generation Failures

If test vector failures occur there are some general guidelines that apply to any type of model (TTM or Simulink):

1. Check to make sure that the lower-level subsystems do not have failures, correct those failures first
2. Check to make sure that the constraints of lower-level subsystem do not preclude satisfiability associated with higher-level subsystems that reference the lower-level subsystems
3. Use the Auto Rotate Convergence Fix Mode in the Vector Generator Properties of VGS
4. Ensure the range settings of inputs variables do not preclude satisfiability
