SIL mode simulation using verification and validation tool from Matlab Simulink Design Validation Toolbox

Hello, I have been trying to simulate my model in SIL mode by providing test cases and using the function slvnvruncgvtest from the "verification and validation tool".However my input is an array signal with boolean elements. I need to define the storage class of each signal as 'GetSet' because I've been doing the read/write operation of global variables on a specific region of on-chip memory. So I need this interface for getting and setting variables. Then while performing the SIL mode simulation, I get an error which states that for GetSet storage class, I can do a SIL mode simulation only for scaler data. However, due to some limitations , it isnn't possible for me to use a different storage class. Can anybody help me out in overcoming this limitation.
