Abstract
The present invention comprises a number transformer that includes an encoder that converts binary numbers to N-NARY numbers. Within an N-NARY number, exactly one of the bits has a value of one and all of the remaining bits have a value of zero. According to some aspects, several N-NARY numbers are generated in response to a binary number. A set of encoding instance selectors defines a partitioning of the bits of the binary number and a range of bits within each partition. The encoder then converts each subset of bits of the binary number to a corresponding N-NARY number, such that exactly one of the bits of each N-NARY number has a value of one and all of the remaining bits of the N-NARY number have a value of zero, and such that the one of the bits of each N-NARY number having a value of one is within the range of bits defined by the corresponding encoding instance selector. The set of encoding instance selectors may define a test point within a circuit under test, and may be produced by an on-chip ROM.
