Vitis Model Composer User Guide (UG1483)

Document ID: UG1483

Version: 2022.2 English

Table 1. Code Generation
Block	Description
Vitis Model Composer Hub	Control implementation of the model.
System Generator	Important: The System Generator token will be removed in a future release of Vitis Model Composer. Please consider updating your model to use the Vitis Model Composer Hub block. The System Generator token serves as a control panel for controlling system and simulation parameters, and it is also used to invoke the code generator for netlisting. Every Simulink model containing any element from the HDL Blockset must contain at least one System Generator token. Once a System Generator token is added to a model, it is possible to specify how code generation and simulation should be handled.

Table 2. Connectors
Block	Description
AIE to HDL	Connect the input port of an HDL block with the output port of an AI Engine kernel or AI Engine graph block using an AXI4-Stream interface.
AIE to HLS	Connect an input port of an HLS kernel block to the output port of an AI Engine block in cases where the data type or complexity of the ports involved do not match.
HDL to AIE	Connect the output ports of HDL blocks to the input ports of AI Engine blocks using the AXI4-Stream protocol.
HLS to AIE	Connect an input port of an AI Engine Kernel or AI Engine Graph block to an output port of an HLS Kernel block in cases where the datatype or complexities of the ports involved does not match.

Table 3. Ports & Subsystems
Block	Description
In1	Create input port for subsystem or external input
Out1	Create output port for subsystem or external output
Subsystem

Table 4. 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 5. Sinks
Block	Description
Display	Show value of input
Scope	Display signals generated during simulation
Stop Simulation	Stop simulation when input is nonzero
Terminator	Terminate unconnected output port
To File	Write data to file
To Workspace	Write data to workspace

Table 6. Tools
Block	Description
DocBlock	Create text that documents model and save text with model
To Fixed Size	Takes a variable size vector as an input and produces a fixed size vector as output.
To Variable Size	Takes a fixed sized vector input and produces a variable sized vector output. The maximum size of the output vector is specified by the Output Size parameter. If there is not enough samples to pack the output, the output will be an empty variable size signal.
Variable Size Signal to Workspace	Save variable size signal data from your Simulink® simulation to the MATLAB® workspace.
