Lesson 4 - Multi-Rate Systems
Debugging Tools
System Generator provides 3 debugging utilities to assist in debugging complex multi-rate systems.
The Sample Time (ST) probe can be connected to any System Generator signal then to a Simulink “display” block
from the “Sinks” library. The sample time for the connected net will appear in the display.
The clk probe is not connected to any inputs but only to a scope output. It displays the master clock. This can be
used with the Clock Enable Probe to display the behavior of the clock enable signal at various points in the down
sampling
