Boundary logic interface

An integrated circuit (IC) comprising:

• a programmable logic region defined by a boundary, the programmable logic region comprising:
• a first column of programmable interconnect elements;
• a second column of programmable logic elements electrically connected to the first column;
• a third column of programmable interconnect elements;
• and
• a fourth column of programmable logic elements electrically connected to the third column;
• a configuration interconnect communicatively coupled to the programmable logic region, the first column and third column of programmable interconnect elements and the second column and the fourth column of programmable logic elements of the programmable logic region being configurable using a configuration frame communicated through the configuration interconnect, the boundary of the programmable logic region being defined by an integer multiple of the configuration frame;
• a first boundary logic interface (BLI) electrically connected to the first column and outside of the boundary, the first BLI being configured to be electrically connected to a first exterior circuit;
• and
• a second BLI electrically connected to the third column and outside of the boundary, the second BLI being configured to be electrically connected to a second exterior circuit.
