Foundation F1.3, XC5200 - Incorrect polarity of pins in AND2B1 components


Keywords: polarity, wrong, netlister, XNF, bubble

Urgency: Hot

General Description:
A problem exists with the XNF netlister for the XC5200 family in Foundation F1.3
where the polarity of the pins in the AND*B* components is reversed. This will
cause incorrect design implementation.

Note that the design will simulate properly from the schematic because the
simulation model is correct. The problem lies in the netlister, so the actual
implemented design will not operate as expected.


A patch is available to fix this problem; it is located in the "File Download" area
of the Xilinx Web site under Software Help -> Foundation area. The patch is
called CONV_ACS.ZIP.
