3.1i CORE Generator - "ERROR: Could not locate Project core fast_ethernet_mac_core_evaluation_board| coreel_microsystems|xc4000|1.0"

Description

Urgency: Standard

General Description:
The following errors are reported after installing 3.X IP Update #4 and starting the CORE Generator application in a pre-existing project:

Solution

These errors will only be reported the first time you start up CORE Generator after installing the IP update, and they can be safely ignored.

These errors are associated with Alliance Cores, whose supported architectures have changed.

For example, the first error regards the CoreEl fast ethernet MAC evaluation board; the architecture designation appears in the message as "virtex+xc4000+++spartan2" above. However, the new version of the core lists "xc4000+spartan+spartan2+virtex" ("spartan" was added).

For the Dolphin and Xilinx Reed Solomon encoder and decoder cores, the difference is that additional architecture support was added: "Spartan" for the Dolphin core, and "xc4000_all," "virtex_all," and "virtex2" for the Reed Solomon cores.

The difference between the supported architecture list in the coregen.prj file and what is listed in the new XCD data file for the core results in a mismatch in these cores' coregen.prj file entries for the pre-existing project.
