Supported Platforms

Embedded Platforms

Embedded platforms available for use with the Vitis core development kit can be found at the Embedded Platforms download page. Embedded processor platforms such as the Zynq UltraScale+ MPSoC ZCU104/ZCU102 base platform as well as Zynq-7000 base platforms can be optionally used for both the Vitis application acceleration development flow, and the Vitis embedded software development flow.

Refer to Installing Embedded Platforms for information on installing and setting up embedded processor platforms.

Changed Behavior

Table 1. Changed Behavior SummaryThe following table specifies differences between this release and prior releases that impact behavior or flow when migrating.
Area	Behavior
Vitis IDE	Previously, accelerated application projects had a system project that contained the application project. This application project contained all the source code and build instructions in a single project. There is now a new project hierarchy that creates a top-level system project with separate projects for each element: a host application project, a hardware kernels project, and a hw_link project. Instead of creating an application project, you now need to create a PL kernel project. The top-level system project is automatically created as part of this process. Existing projects from earlier releases must to be updated to the new project hierarchy. When you open the older projects, you will be prompted to upgrade the project to the new structure. The tool will handle this upgrade for you. It is recommended to back up your existing projects before the upgrade.
Vitis compiler	The `--profile_kernel` command has become the `--profile` command.
	The `--dk` command has become the `--debug` command.
	The `--package` command previously did not require renaming the xclbin file, but now either renames the output file to a.xclbin by default, or names it according to the `-o` option.
Vitis HLS	The `DISAGGREGATE` pragma or directive previously could not be applied to structs on the interface. Disaggregating structs on the interface is now supported.
Vitis HLS	The `ARRAY_PARTITION` pragma and directive was not previously supported for arrays defined on the function interface. It is supported in this release.
