When attempting to generate or insert an ATC2 Core in ChipScope 7.1.04i, you will encounter one of the following two sets of errors:
1. For the inserter flow, the following error will occur during core insertion:
"ERROR: An internal error has occurred.

ERROR:MapLib:661 - LUT3 symbol"

"Warning: EDIF Netlist being generated
