  • Asynchronous controller generation method
    Patent number: 6594815
    Abstract: A method for generating an asynchronous controller includes a process controller formation step S100 of forming a signal transition graph representing a state of change in input/output signals of a plurality of process controllers PC1˜PC4 for outputting control signals necessary for executing a process corresponding to a node in a data flow graph showing a performance sequence between a plurality of nodes each representing a process and a plurality of processes, a process sequencing controller formation step S400 of forming a signal transition graph of a process sequencing controller PSC according to a performance sequence of the process controllers PC1˜PC4 from the data flow graph, and a logic synthesis step S500 of generating an asynchronous controller in a logic synthesis program, by using the state of change in the input/output signals on the signal transition graph of the process controllers PC1˜PC4 formed in the process controller formation step S100 and the state of change in the inpu
