    Analysis of the state diagram correctness of automatic logic control systems on FPGA paper
    (2019) Shkil, O. S.; Rakhlis, D. Y.; Kulak, E. M.; Filippenko, I. V.; Miroshnyk, M. M.; Hoha, M. V.
    The work is dedicated to verification of automatic logic control systems by analyzing the correctness of state diagrams of control finite state machines which are represented in the form of the code in the hardware description language. As a method for state diagram analysis the, it is proposed to use the concept of orthogonality, as a system of incompatible events. Analysis of the correctness is carried out by analysis the results of behavioral modeling and logical synthesis using CAD tools.

    Synchronizing sequences for verification of finite state machines
    (2019) Shkil, O. S.; Rakhlis, D. Y.; Kulak, E. M.; Miroshnyk, M. V.; Pahomov, Y. V.; Miroshnyk, A. M.
    Abstract—The method of detection and localization of design errors in HDL-models of finite state machines with arbitrary output functions was proposed. The diagnostic experiment is carried out bypassing all arcs of the Mealy machine, starting from the initial vertex, including for machines of the "non- exclusive" class. To ensure the return of the machine with a possible design error in the initial state, it is suggested to use synchronizing sequences. Diagnostic experiments were performed in the Active-HDL design environment.

    Testable design of control digital automatic machines
    (2020) Shkil, O. S.; Rakhlis, D. Y.; Kulak, E. M.; Filippenko, I. V.; Miroshnyk, M. M.
    Abstract—The aim of the work is to analyze hardware costs of ensuring the testability of finite state machines with various options for organizing an additional transition between FSM’s states depending on the presence of an unconditional transition, a conditional transition, and the absence of transitions between states of analyzed FSM. The conclusion on additional hardware costs is made on the basis of a comparison of synthesis results of testable HDL-models by means of CAD FPGA. The paper solved the problem of computer-aided design of testable control FSM based on the application of methods for setting FSM in a given state. The best way to organize additional transitions during setting of control FSM in an arbitrary state is the transition for which the total hardware cost estimate for the excitation functions is minimal, taking into account the coding of FSM’s states.
