Abstract :
A test vehicle for a wafer scale FPGA has been developed. A symmetrical RAM-programmable FPGA, lookup table based logic block and segmented channel routing are used. In this paper, we emphasize on the practical problems inherent to wafer scale FPGAs: redundancy, power shorts, clock distribution, cell and bus testing. The laser-link process is used to interconnect working cells and form a defect free array of FPGA cells. The defect avoidance algorithm is designed to minimize the delay between working cells, an important parameter for FPGA users
