| Research Abstract |
We have developed a carry select adder which can be tested by a test set whose cardinality is independent of the operand size, and a parallel prefix adder which can be tested by a test set whose cardinality is proportional to the depth of the circuit. For multiplier design, we have developed a 4-2 adder tree, as well as other adder trees, which can be tested by a test set whose cardinality is independent of the operand size, and also shown that any partial product compressor consisting of carry save adders can be tested by a test set whose cardinality is proportional to the depth of the circuit. We have also developed a prototype tool for synthesizing easily testable parallel prefix adders and 4-2 adder trees.
