XC4000/A: XC4000 and XC4000A bitstreams are NOT compatible!

Problem Title:
XC4000/A: XC4000 and XC4000A bitstreams are NOT compatible!


Problem Description:
Urgency: Standard

Keywords: 4000A, 4000, bitstream, configuration


The bitstreams for XC4000 and XC4000A parts are not compatible. The 4k data
book  (Aug. '92) incorrectly lists the 4003/4003A and 4005/4005A parts
as having the same frame and data sizes on p.26.  The A parts have 4 bits
fewer per frame, which is consistent with the reduced amount of interconnect in
these parts.
