Getting the current simulation time in Simulink

Hi,

I am building a discrete event simulation in Simulink using the SimEvents toolbox. In the simulation model, I am using several matlab function blocks that need to access the current simulation time.

Currently I am doing this by using the clock attached to timed to event signal block and providing this as the input to each of the Matlab function blocks. Is there a way to access the current simulation time globally from each of the matlab function blocks without having to have the clock as an input parameter to each of the function blocks?

I appreciate your help

In general this highlights the need of the current simulation time for SimEvents being easily accessible for MATLAB Function blocks, where the current simulation is the time the input signal was created. The SimEvents debugger contains a function ( t=simtime;), which might be useful. Unfortunately its use within a Matlab function block is not straight forward (or possible!?).

By the way there is an interesting page about deriving custom statistics. The "Compute a Time Average of a Signal" example suggests that a Digital Clock could be used, which would avoid the "time to event signal" block. Unfortunately it does not work. Using a "clock" plus a "time to event signal" instead does not generate the desired timings and signal values.

How can the "current signal simulation time" be fed (or read within) a Matlab Function block?

Unlike in S-functions, where you can use ssGetT, I don't think there is a good alternative for MATLAB Function block other than what TAB suggested.
