Abstract
A system is provided for yield enhancement in programmable logic. The system includes first and second random combinational logic, first and second sets of IP logic blocks, and first and second BIST/MUX controllers. The first controller is electrically connected between the first logic and each of the blocks in the first set and electrically connected between each of the blocks in the first set and the second logic. The second controller is connected in the same manner with respect to the second set of blocks. The controllers are configured to test the blocks for functionality or non-functionality, to identify functional ones of the blocks and to provide electrical connections between a predetermined number of the functional blocks and the first and second logic.
