I am working on MATLAB 2017a. I am using SLDV for Model Verification. My model has blocks (ex Integrator block, Trasnfer Function Block etc) which are unsupported for functioning of SLDV. The SLDV saying the model is incompatible for test generation. The error shown in Daignostic Viewer is 'Test_Model' is incompatible for test generation with Simulink Design Verifier' and 'Test_Model/Subsystem/BlockNamer/Transfer Fcn' of type TransferFcn cannot be stubbed'. Even if I use 'Block Replacement' option from design verifier, still showing the same error. Could anyone suggest any other way to tackel the problem? or any equivalent blocks that can be used in place of unsupported blocks.
