我们指的是虚拟模拟量（VA）作为在用于生成或处理音乐声音的非线性模拟电路之后建模的广泛类别的数字实现。因此，参考模拟系统通常由通过电端口彼此连接的一组块表示，并且通常表现出非线性行为。因此，将非线性波数字建模视为此类系统快速原型的可靠方法似乎是很自然的。在本文中，我们讨论了如何非线性波数字建模可以卓有成效地用于此目的，特别是参考特殊的块和连接器，使我们能够克服实施的困难和潜在的限制，这样的解决方案。特别是，我们解决了一些问题，是典型的VA和物理建模，关于如何适应特殊的块到WD结构，如何使不同的WD结构之间的相互作用，以及如何适应结构和拓扑变化的飞行。
We refer to ¿Virtual Analog¿ (VA) as a wide class of digital implementations that are modeled after nonlinear analog circuits for generating or processing musical sounds. The reference analog system is therefore typically represented by a set of blocks that are connected with each other through electrical ports, and usually exhibits a nonlinear behavior. It therefore seems quite natural to consider Nonlinear Wave Digital modeling as a solid approach for the rapid prototyping of such systems. In this paper, we discuss how nonlinear wave digital modeling can be fruitfully used for this purpose, with particular reference to special blocks and connectors that allow us to overcome the implementational difficulties and potential limitations of such solutions. In particular, we address some issues that are typical of VA and physical modeling, concerning how to accommodate special blocks into WD structures, how to enable the interaction between different WD structures, and how to accommodate structural and topological changes on the fly.
