Stitching parameters

Stitching parameters can be only set from the RTL Design Flow Manager Preferences dialog that is available when you have started IP-XACT stitching. For instructions, see Stitching.

Table 2. IP-XACT stitching settings




Ignore IP-XACT Bus Definitions VLNV Version Fields

When selected, bus interface version fields on components are not compared against bus definition versions when checking for bus compatibility.

Run IP-XACT Stitching Process in Verbose Mode

When selected, an extended messaging mode is used that provides additional progress information.

Create verbose comments in the generated RTL

When selected, basic comments are added to the RTL during the stitching process.

Run IP-XACT Stitching Process in Strict Mode

When selected, forces a strict strategy to be used when stitching. This is useful for IP-XACT design verification, and the following policies apply:

  • failure when an invalid default value is detected for input or bidirectional signals, in IP-XACT component definitions

  • failure when connected signals do not have the same size, or the same left and right bits

  • additional warning messages are output.

Output VC file

When selected, a <design name>.vc file is generated at the same location as the top-level <design name>.v file. The .vc file contains references to all the .v files, directories, and other directory dependencies, and you can use it to compile the entire design.

Auto Add Stitched System to Component Library

When selected, AMBA Designer adds the stitched system to the Component Library.

Absolute path for .v files in generated IP-XACT file

When selected, the generated IP-XACT file includes the absolute path to the .v files instead of the relative path.

Use instance names in nets

When selected, the instance name of the components being connected are used as part of the net name.

Export all unconnected

When selected, all the unconnected signal ports are exported to the top-level of the design. This is equivalent to manually creating external ports for all the unconnected signal ports in the design.


Only signal ports, not bus interface ports, are exported to the top-level of the design.

Stitcher Plugins

System Configuration Export

When selected, AMBA Designer outputs the system configuration files and a script file render.csh into a subdirectory called <SysName>_config. You can then move the content of the subdirectory to some other system on which AMBA Designer and other required IP and licences are installed to recreate the system there by executing render.csh.

For instructions, see Recreating a stitched system from exported configuration files.
