Xilinx Coregen IP Customizer Causes Exception During Customization

I'm running Xilinx ISE Webpack 7.1.04i with ISE 7.1 IP Update 3 installed on Windows XP SP2. When I run Core Generator and try to instantiate a core (e.g. Single or Dual Port Block Memory), there's a popup window saying 'Launching IP Customizer', and then another popup window saying Exception encountered. After pressing OK, status bar shows 'An Error occured during customization' and nothing else happens. Adding a core from the Project Navigator produces a similar result (without popup windows) and the status window shows 'Customizing IP... An Error occurred during Customization.'

The same error occurs for many different cores (but not all), and there is no apparent regularity with respect to what cores (versions, or types of cores) cause the exception, and which don't. It also doesn't matter which device family I am targeting (I've tried Virtext-4 and Virtex-II Pro).

I have tried running CoreGen with limited memory (As suggested at

, but that doesn't help).

Has anyone encountered a similar problem, or knows of any workarounds?

Regards,

Fred

Hi Fred:

I am also getting the same error. Interestingly enough, I am using the same version of ISE, same IP update, and same version of Windows XP. I've also tried Dual Port Block Mem versions 6.1 and 6.2 in the CoreGen tool and get the same error. In my application, I am targetting a VirtexII.

I'm not aware of any work-arounds but also hoping someone can jump in and provide suggestions!

Dean.

According to this page, ISE Webpack does not support the Core Generator.

Maybe they'll change their policy with 8.1. It would be nice if they had an informative error message about this. It's funny how some of the IP works by just installing the updates.
