Table 3. Signal Routing
Block	Description
Bus Creator	Create Signal Bus
Bus Selector	Select signals from incoming bus
From	Accept input from Goto block
Goto	Pass block input to From blocks

Table 4. Sinks
Block	Description
Display	Show value of input
Scope	Display signals generated during simulation
Stop Simulation	Stop simulation when input is nonzero

Table 5. Source
Block	Description
RTP Source	Used as a source for the RTP input of an AI Engine block. When the RTP input is a scalar, the 'RTP Value' parameter should be a row vector. At each time step, the output is set to one of the elements of the vector starting with the first element. If an element of the vector is NaN, at the corresponding sampling time, the output will be an empty variable size signal.

Block	Description
AIE Class Kernel	Import class-based AI Engine kernels.
AIE Graph	Import an AI Engine graph.
AIE Kernel	Import an AI Engine kernel.
