Is there an "Advance" signal in time block available in simulink?

Is there an "Advance" signal in time block available in simulink? Blocks are only available for introducing delay... Please help me with tis... Any procedure for advancing the signal ahead in time(in simulink)?

I dont think so there is a block for advancing the time. U must try to create your own block to do this. If u get any idea in this just post it here so that others get to know.

say what? technically, this doesnt make any sense at all. you are solving an ODE with simulink (thats all simulink does). advancing the signal ahead in time means knowing at time t_i (in which you calculate x_i) the values of x_i+1. Since x_i+1 depends on x_i but you need x_i+1 to get x_i, this wont work in simulink.

Delay all of the signals except the one signal that you want to advance.

I have already done that. I am not able to get the desired result. Any others please??
