MATLAB/DSP Builder megablock timing issues

I am trying to use the fir_compiler_v11 Megablock in MATLAB/Simulink but can't figure out how to change the internal timing. I have 200 coefficients that I want to use only one multiplier with. I hav...

Simulink works in "seconds" and has doesnt really have a concept of real time in discreat mode. Consider each "second" as a clock tick, hence why you only get 1 result every 200 seconds, because 1 multiplier has to compute 200 values, and at only 1 per sample (as this is a speed of a multiplier) you only get a result every 200 clocks.

Why do you want only 1 multiplier?
