We realize autonomous Boolean networks by using logic gates in their autonomous mode of operation on a field-programmable gate array. This allows us to implement time-continuous systems with complex dynamical behaviors that can be conveniently interconnected into large-scale networks with flexible topologies that consist of time-delay links and a large number of nodes. We demonstrate how we realize networks with periodic, chaotic, and excitable dynamics and study their properties. Field-programmable gate arrays define a new experimental paradigm that holds great potential to test a large body of theoretical results on the dynamics of complex networks, which has been beyond reach of traditional experimental approaches.
我们使用现场可编程门阵列中的逻辑门的自主操作模式来实现自治布尔网络。这使我们能够实现具有复杂动态行为的时间连续系统，这些系统可以方便地相互连接成具有灵活拓扑结构的大规模网络，其中包括时滞链路和大量节点。我们展示了如何实现具有周期性、混沌和兴奋动力学的网络，并研究了它们的性质。现场可编程门阵列定义了一个新的实验范例，具有很大的潜力来测试大量关于复杂网络动力学的理论结果，这是传统实验方法所无法企及的。
