LOTOS is a specification language that aims at describing the dynamic behavior of complex systems ( formal description language ). LOTOS主要是用来描述复杂系统动态性的说明语言(形式描述语言),是可操作的。
Upon the top-down design rule, a behavior model of this chip was created during the upper level designing, by using the standard Hardware Description Language VHDL, and a behavior-level virtual computer enviroment was developed on the basis of the model. 按照自顶向下的设计原则,在芯片的上层设计阶段,采用了标准的硬件描述语言VHDL建立了该芯片的行为模型,并以此为基础建立了该芯片的行为级虚拟机环境。
The behavior of multi-port-component ( functional component ) is described with DAEs ( differential and algebraic equations ), coded by analogy hardware description language. 该方法采用常微分和代数方程描述组件的行为,混合信号硬件描述语言作为组件及其网络的建模语言。
