In this paper we introduce a set of resources used to describe multiple-valued (MV) functions: a set of multiple-valued benchmarks and a file format specifically designed to accommodate the requirements of multiple-valued function representation. The proposed functions are intended for use as reference benchmarks for automated synthesis algorithms of multiple-valued circuits. In the MV domain, functions can be represented using fixed radices (e.g. ternary, quaternary, etc) or using mixed radices (hybrid functions). Since such functions are harder to represent with the existing PLA specification, in this paper, we introduce the eXtensible Quantum Specification (XQS) file format which is based on the well-known YAML file specification.
