Is delay_ms() can be used with simulink?

Hello everyone,

I'm currently working with a dspic33f and simulink. I downloaded the dsPIC blockset perfectly and was able to begin programming with a tutorial. I have a blinking LED. I would like to know if there is a specific block corresponding to de delay_ms() function (delay_us() too ) in Simulink. If no I would like to know how to do such a thing.

Should I import the libpic30 library in a dsPIC project in Simulink? How could I do this? Should I rewrite the functions?

Thanks,
