This block allows you to import an AI Engine graph.

AI Engine/User-Defined Functions
Description
The AIE Graph block allows you to import an AI Engine program that consists of a dataflow graph specification written in C++.
Parameters
- Graph file
- Specifies whether the graph import should be done using the header file (*.h) or using source file (*.cpp). By default the header file is selected.
- Graph Header file(*.h)
- This is the mandatory string that specify the file (.h), where the application graph class is defined and the Adaptive Data Flow (ADF) header (adf.h), kernel function prototypes are included. This parameter is only visible when you choose the Header file (*.h) option in the Graph file.
- Graph Source file (*.cpp)
- This is the mandatory string that specify the file (.cpp), where the adf dataflow graph is instantiated. This file should contain the main() function, from where the dataflow graph initializes and runs. This option is available only when the Source file (*.cpp) is selected in Graph file.
- Graph class
- This is a mandatory string that specifies the name of the graph class. This parameter is only visible when you choose the Header file (*.h) option in the Graph file.
- Graph search paths
- This is a vector of strings that specifies the search paths where header files, kernels, and other include files can be found and included for simulation. The search path $XILINX_VITIS/adf/include (where adf.h is defined) is included by default and does not need to be specified.
- Preprocessor options
- This is an optional parameter and should be specified with a preprocessor
argument for downstream compilation with specific preprocessor options. The
following preprocessor option formats are accepted and multiple can be
selected: ‘-D<name>’ and
‘-D<name>=<definition>’. That is, the optional
argument must begin with the '-D'
string and if the option
<definition>value is not provided, it is assumed to be 1.
