2013.3 Vivado IP Flows - Example design for an IP core opens with only the IP core in the project

Description

On some (typically Windows 7 64-bit OS PCs), if a user selects a generated IP core and clicks "Open IP example design" in the right-click menu, a new project for the IP core is created but only the <core name>.xci is contained in the project; the other files in the example design are not added into the new project.

Solution

There is a possible race condition in Vivado Design Suite 2013.3 that will be exhibited on only some systems. The root cause for the issue is before running the new project creating Tcl, the source code of the example design is removed.

Example: In Vivado 2013.3, open_example_design command will do the following steps for an IP core named "cpri_test":

  1. Generate the source code of the example design(cpri_test dir) and the new project creating Tcl(cpri_test_ex.tcl).
  2. Run the new project creating Tcl(cpri_test_ex.tcl).
  3. Remove the example design(cpri_test dir) and the new project creating tcl(cpri_test_ex.tcl).

If step 3 finishes executing before step 2 copies the file to the new project, the new project will not have all the needed files.

To work around this issue:

  1. Save the source code of the example design(cpri_test dir) and the new project creating Tcl(cpri_test_ex.tcl) before they are removed, and
  2. then run cpri_test_ex.tcl (source cpri_test_ex.tcl) in Vivado Tcl console to create the new example project.
  3. Ex: Tcl: /project_1/project_1.srcs/sources_1/ip/cpri_test/cpri_test_ex.tcl ; cpri_test dir: /project_1/project_1.srcs/sources_1/ip/cpri_test/cpri_test

  4. Open the example design on the other PC, and then copy it to your PC.


This issue has been fixed in Vivado Design Suite 2013.4.
