how to bring a nonlinear model simulation at operating point using simulink environnement?

I built a multivariable nonlinear model in simulink environement (it contains integrators,constants, products block...). How can I bring this simulation nonlinear model at a specified operating point.(specified values of the two inputs and four state variable) I want to confirm if my linearized model around this operating point and the nonlinear model brought at this operating point have the same openloop responses. Any help or advice will be appreciated. Thanks
