This topic discusses the low-level files Vitis Model Composer produces when you select HDL Netlist as the Export Type and click Export in the Model Composer Hub block. The files consist of HDL that implements the design. In addition, Model Composer organizes the HDL files, and other hardware files into an AMD Vivado™ IDE Project. These files are written to the folder <target directory>/ip/<design_name>/src. <target directory> is the target directory specified on the Model Composer Hub block. If no test bench is requested, Model Composer produces the following key files:

Table 1. Compilation Files
File Name or Type Description
sysgen/<design_name>.vhd/.v This file contains a hierarchical structural netlist along with clock/clock enable controls
sysgen/<design_name_entity_declarations>.vhd/.v This file contains the entity of module definitions of HDL blocks in the design.
hdl_netlist/<design_name>.xpr This file is the Vivado IDE project file that describes all of the attributes of the Vivado IDE design.

If a test bench is requested, then, in addition to the above, Model Composer produces files that allow you to compare simulation results. The comparisons are between Simulink® simulation results and corresponding results from Questa, or any other RTL simulator supported by AMD Vivado™ IDE such as Vivado simulator, or VCS. The additional files are as follows:

Table 2. Additional Compilation Files
File Name or Type Description
Various .dat files These contain the simulation results from Simulink.
sysgen/<design_name>_tb.vhd/.v This is a test bench that wraps the design. When simulated, this test bench compares simulation results from the digital simulator against those produced by Simulink.
