5.1i ISE - "ERROR: IBISWriter:39 - Spartan-3 is an unsupported architecture"

Description

Keywords: IBIS, Project, Navigator, ISE, generate, IBISWriter, Spartan-3, model

Urgency: Standard

General Description:
When I select "Generate IBIS Model" for a design using a Spartan-3 device, the IBIS writer fails with the following error:

"ERROR: IBISWriter:39 - Spartan3 is an unsupported architecture.
Use ibiswriter -h to list supported architectures.

Completed process "Generate IBIS Model"."

Solution

In the 5.1i software, the IBISWriter does not support Spartan-3 devices.

IBISWriter cannot add support for an architecture until the IBIS buffer models are released. The buffer models were not available at the time of the software release because they are written based on actual silicon devices.

The "Generate IBIS Model" option for Spartan-3 is removed from the Project Navigator Process list for ISE 5.2i. The option will be added back in the ISE 6.1i software when the IBISWriter supports these devices.
