Abstract: Methods, systems, and circuits for implementing multi-clock designs in asynchronous logic circuits are described. A method may include associating one or more data tokens with a clock domain of a multi-clock domain netlist. A durational relationship between a clock period associated with the clock domain and one or more other clock domains of the multi-clock domain netlist may be determined. Data tokens used in other clock domains may be transformed based on the determined relationship.

Abstract: Methods, systems, and circuits for forming and operating a crossbar structure in an asynchronous system are described. One or more input ports of a programmable crossbar structure may be connected to send data to one or more output ports. A group of output ports each receiving data from an input port may be connected to send, in response, control signals via a programmable element to the input port. The number of programmable elements used may be determined by the number of input ports being copied to more than one output port. Additional methods, systems, and circuits are disclosed.

Abstract: A synchronous circuit design is converted to an asynchronous circuit by converting synchronous circuit logic to an asynchronous circuit logic, and one or more additional tokens into the converted asynchronous circuit. The circuit is initialized with a desired additional number of tokens placed in the asynchronous circuit, or a desired number of tokens are inserted at an input before taking tokens from an output.
