Introduction
You can include an external traffic generator process while simulating your application to dynamically generate data traffic on the I/O, or to capture output data from the emulation process. The AMD provided C++ library can be used to create the traffic generator code as described in the following sections.
The C++ library having the API is divided into API for
sending/receiving data in the form of byte array. The user data before sending needs
to be converted into byte array and the data is received in the form of byte array
which can be further converted to user data type using conversion APIs. There are
also advanced API for packet level granularity if you need more control over
transactions. For seamless interaction of traffic generators with simulation
process, the API gives you control over sending or receiving the data without much
worrying about managing packet level details like TLAST, this is auto managed by the sim_IPC infrastructure.
For C++, the APIs are available at:
$XILINX_VIVADO/data/emulation/cpp/inc/xtlm_ipc/axis/You can build the executable with the following include path:
-I $XILINX_VIVADO/data/emulation/cpp/inc/xtlm_ipc/axis/and linked against library as:
-L $XILINX_VIVADO/data/emulation/cpp/lib/And use -lxtlm_ipc with a gcc compiler.
The C++ API are categorized as follows:
