Project Navigator - Project Migration does not update IP cores to the latest version


When Project Navigator opens a project created in a previous version of thesoftware, you are given the option to upgrade (Migrate) the project.If the Project contains IP cores, the IP cores are not upgraded to the latest IP core version.Why?


The reason for this is to give customers flexibility; rather than assume the intentions and needs when opening a project from a previous version, the choice has been left to the user.

Each IP core in a design is its own subproject of the top level design.Project Navigator would have the technology to update each of these projects at the time of migration.However, it is not done automatically for the following reasons:
  • The IP core is considered a source by Project Navigator.Project Navigator maintains the location, existence, and status of the source files, but not the content.
  • There is a possibility of a long generation time for projects containing multiple IP cores.
  • Not all cores have newer versions, and therefore, do not need to be regenerated.
  • A user might not want to update a core.Following are some example reasons:
    • Theexisting Core version has been tested and qualified.
    • Theexisting Core version is not supported in the new woftware, but the core has been tested and no changes are needed
    • Another engineer is responsible for themaintenanceand operation of the I core.
  • Once a project is open, the user has the option to upgrade or regenerate all or individual IP cores as desired.
  • The user might only be opening the project to evaluate a portion of the that is not related to the IP core(s) in the project.
  • Once a change was made, it could not be undone without extracting the IP core from the archived version of the project.
