Configuring SDSoC Settings through the GUI

The SDx™ GUI provides different views for you to manage SDSoC™ projects and builds, debug the design, view the design, and analyze the design.

The Assistant view in the SDx GUI displays the project and all of the build configurations that are part of the project. All of the settings for the project, and for building and debugging the project are accessible from the Assistant view, as described in the following sections.

TIP: Because the SDx IDE is based on Eclipse, many of the dialog boxes and settings are standard options available through the Eclipse environment. You can view the Eclipse help at: http://help.eclipse.org.

SDSoC Project Settings

To edit the SDSoC project settings, select the project in the Assistant view and click the Settings icon () to bring up the Project Settings window.

Project Settings provides quick access to the project settings through the Project name: link. The Project flow: link guides you to the www.xilinx.com web site for the SDSoC flow. You can also change the platform and the system configuration for the current project using the browse button.

SDSoC Build Configuration Settings

Build Configuration Settings

To edit the settings for any of the build configurations under the project, select a specific build configuration in the Assistant view and click the Settings icon () to bring up the window with the build configurations.

The Build Configuration Settings dialog provides a convenient way to make adjustments to your build configuration. You can change the build target as described in Building the SDSoC Project.

You can enable analysis options like performance estimation, and event tracing as described in Profiling and Optimization, and specify the root function to exclude certain code from performance estimation. These options are only available when the build target is hardware. See SDSoC Environment Getting Started Tutorial (UG1028) for more information on using these options.

TIP: Hold the mouse over a setting to display an informative tooltip about what that setting does.

The Data motion network clock frequency drop-down shows available values for the clock frequency in between the platform and hardware accelerated functions. For more information, see Selecting Clock Frequencies.

Use the Generate SD card image option to create the files required to allow booting your board from an SD Card. This option is only available when the build target is hardware.

Finally, the Edit Toolchain Settings link at the bottom of the dialog box opens the SDS++/SDSCC Compiler Options dialog box to let you set sds++ system compiler and sds++ linker options, including specifying directories, additional libraries, and command line options for the active configuration.

SDS++/SDSCC Compiler Options

The SDS++/SDSCC Compiler sections of the Tool Settings dialog box lets you set various options for the sds++ and sdscc commands that are passed when the compiler is called. To access the Tool Settings dialog box, select the Edit Toolchain Settings link from the Build Configurations dialog box.

The Settings dialog box lets you specify which build configuration you are specifying the settings for. Select the Configuration field at the top of the dialog box to specify any of the current build configurations, or select All configurations to change settings for all.

TIP: The SDS++ and SDSCC compilers are based on GCC, and therefore support many standard GCC options including some documented here. For more information refer to the GCC Option Index.

Compiler Symbols Settings

Click Symbols under the SDS++ Compiler to define compile time macros that are passed with the –D option when calling the sds++ command.

Under the Defined symbols (-D) field, you can add multiple symbols by clicking the add () icon to add each symbol.

Under the Undefined symbols (-U) field, you can cancel any previous definition of a defined symbol.

Compiler Warnings Settings

Command options related to compiler warnings (-W) are provided through the Warnings section.

Compiler Optimization Settings

Compiler optimization flags (-O) and other optimization settings can be specified in this section.

Compiler Debugging Settings

Specify debug Level (-g<level>) and other debugging flags are specified through this section in the GUI.

Compiler Profiling Settings

Enable profiling (-pg) to generate extra code to write profile information for analysis of the application.

Compiler Directories Settings

Include Paths for the SDS++ Compiler are added under the Directories option. You can add directories to the Include Paths by clicking the add () icon to add each symbol.

Compiler Miscellaneous Settings

Any other flags that need to be passed to the SDS++ Compiler are added to the Miscellaneous section.

Note: These options can include any SDS++ Compiler options as described in SDx Command and Utility Reference Guide, as well as any GCC standard options not specifically addressed in other sections of this dialog box.

Inferred Options

Software platform inferred flags and software platform include paths are added under the Inferred Options section.

SDS++ Linker Settings

The SDS++ Linker sections of the Tool Settings dialog box lets you set various options for the sds++ command that are passed when the linking stage of the build process is run. To access the Tool Settings dialog box, select the Edit Toolchain Settings link from the Build Configurations dialog box.

The SDS++ Linker page shows the sds++ command and any additional options to be passed when calling sds++ for the linking stage.

TIP: The SDS++ command is based on GCC, and therefore supports many standard GCC linking options including some documented here. For more information refer to the GCC Option Index.

SDS++ Linker General Settings

Some general setting for the SDS++ linker are specified in this section.

SDS++ Linker Libraries Settings

Specifies Libraries (-l) and the library search path (-L) for the SDS++ linker command. You can add libraries or library search paths by clicking the add () icon.

SDS++ Linker Miscellaneous Settings

Any other flags that needs to be passed to the SDS++ Linker can be provided through the Miscellaneous section.

SDS++ Linker Script Settings

The path and file name of the SDS++ Linker Script is provided in the Linker Script field.

SDS++ Linker Inferred Options

Software platform inferred flags are added under the Inferred Options section.
