How do I create a trigger for a subsystem which has to run faster than the rest of the simulink model?

I have a transmission plant simulink model which is interconnected to complete vehicle model. I need to run this plant model faster than rest of the model. This plant model is designed with a triggered subsystem and trigger is given from a dSPACE timer hardware interrupt block which is actally designed for HIL testing. When I run it on simulimk (called offline analysis), plant is generating weird values as dSPACE interrupt is not working here. I am looking for an alternative block available in simulink library to replace the dSPACE timer interrupt and run the simulations so that plant block has higher sample time and rest of the model has normal sample time.
