The Tsamp block sets the clock domain inherited by all downstream blocks.
When you use the Tsamp block, you must select a variable step solver in the Simulink
configuration parameters. Unless the downstream clock is an exact, slower multiple
of the upstream clock, the simulation results may not match ModelSim; in this case it
is better to use a
