5.2isp1 IBISWriter - No buffer model is available for Spartan-IIE LVCMOS 2.5V

Description

Keywords: IBIS, writer, IBISWriter, Spartan-IIE, buffer, model, LVCMOS, 2.5V, LVCMOS2, LVCMOS25

Urgency: Standard

General Description:
The ISE 5.2isp1 design implementation software refers to the LVCMOS 2.5V I/O standard for Spartan-IIE as "LVCMOS2". Because the associated IBIS model is called "LVCMOS25", IBISWriter erroneously reports that a buffer model is not available.
