4.2i ISE - "ERROR: IBISWriter:39 - Virtex2p is an unsupported architecture"


Keywords: IBIS, Project Navigator, ISE, Generate, IBISWriter

Urgency: Standard

General Description:
When I select "Generate IBIS Model" for the Virtex-II Pro family or the Spartan-II E family, the IBIS writer fails, reporting the following error.

"ERROR: IBISWriter:39 - Virtex2p is an unsupported architecture.
Use IbisWriter -h to list supported architectures.
EXEWRAP detected a return code of '2' from program 'ibiswriter'

Done: failed with exit code: 0002."


In the 4.2i software, IBISWriter does not support either Virtex-II Pro or Spartan-II E 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 IBISWriter supports Spartan-II E devices in the 5.1i software release. The option to create an IBIS model for Virtex-II Pro devices was removed from Project Navigator 5.1i and will be added back in when the IBISWriter supports these devices.
