General Description: After performing a Base or Base-Express installation with the XC3100L selected along with almost any other combination of families, the Xilinx automation may be unusable. The problem may show itself in one of two ways:
At the end of synthesis (exporting XNF), I get "Automation caused an exception, exit code 800706BA". Attempting to Implement the design will give that error along with "XIE Internal error 1347170868". The XNF exists and is fine. This will happen for any selected device.
Another error that may occur entering the Implementation phase is error code 80010104. This also occurs with any family.
If you are a Base user that needs to use the XC3100L family, select the XC3000L family in addition to the XC3100L. This will correct any automation errors.
Note: This problem is fixed in the F1.5i release.
Do not select the XC3100L for a Base install. This part is not selected by default.
