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. |
The ARRAY_PARTITION pragma and directive was not previously
supported for arrays defined on the function interface. It is supported
in this release. |
