Description

The following error messages occur when I attempt to open a CORE Generator project with the part 'xc3s700an-5fgg484':

WARNING:coreutil:928 - Unable to find 'xilinx.com:ip:dcm_v13_1:1.0' within repository. 
ERROR:sim:879 - Part 'xc3s700an-5fgg484' is not valid for component 'xilinx.com:ip:dcm:13.1'. 
WARNING:sim:863 - Failed to create component instance for XAW file 'C:\Users\myproj\test2.xaw' during project migration.

What is the reason for the errors?

Solution

XAWinfo is returning the wrong information for this Xilinx Architecture Wizard core which causes the CORE Generator tool to fail to reconcile the core with the IP.

Work-arounds:

To create new cores

1. Change the project part to any other (e.g., change the speed grade from -5 to -4).
2. Change the project part back to the original part.
3. Generate desired cores.

To open existing cores:

1. Change the project part to any other (e.g., change the speed grade from -5 to -4).
2. Change the project part back to the original part.
3. Import all of the IP Cores in the project (for XAW select type ALL).
