FPGA（Field-Programmable Gate Array）是可编程逻辑器件，正逐渐在工业控制市场中崭露头角，被视作处理高集成模拟和数字输入输出（I/O）、浮点运算以及实现多处理节点无缝连接的理想解决方案。这篇英文文献《Building Programmable Automation Controllers with LabVIEW FPGA》主要探讨了如何利用National Instruments公司的LabVIEW FPGA模块来开发定制化的工业自动化控制器。 LabVIEW是一个广泛应用的软件开发环境，它为各种PAC（Programmable Automation Controller）系统提供了强大的支持。通过LabVIEW，开发者能够构建针对工业应用的专用I/O接口，如NILabVIEW FPGA模块。这个模块结合了可重构I/O (RIO) 硬件，使得National Instruments能够提供一个直观且易于使用的平台，将FPGA技术的灵活性和定制化融入到工业自动化系统中。在使用LabVIEW FPGA模块时，用户无需深入了解底层硬件描述语言（HDLs）或板级硬件设计细节。开发者可以跨不同RIO硬件目标平台定义嵌入式逻辑，实现快速和高效的系统设计。这极大地简化了工程师的工作流程，使他们能够专注于应用层面的设计，而不是被硬件复杂性所困扰。文章的核心内容包括了以下几个关键点： 1. **PACs的兴起**：随着工业控制需求的增长，PAC因其高度集成的优势受到青睐，特别适用于需要大量处理能力的应用。 2. **LabVIEW的作用**：作为核心开发环境，LabVIEW提供了统一的工具集，使得开发定制I/O和FPGA逻辑变得简单。 3. **FPGA模块的优势**：通过LabVIEW FPGA模块，用户可以在不了解底层硬件的情况下进行逻辑设计，提高开发效率。 4. **RIO硬件和灵活性**：RIO硬件允许FPGA技术在多种硬件平台上复用，提供了极大的灵活性。 5. **易用性和定制化**：通过LabVIEW，开发者可以快速地创建符合特定工业应用需求的自动化控制器，无需深入硬件设计。这篇文章是针对初学者的一份实用指南，介绍了如何利用LabVIEW FPGA模块开发出功能强大、适应性强的工业自动化控制器，强调了FPGA技术在工业控制领域的潜力和LabVIEW在简化开发过程中的核心作用。对于学习和实践FPGA在工业自动化中的应用，这篇文章是一份宝贵的参考资料。

An FPGA is a chip that consists of many unconfigured logic gates. Unlike the fixed,

vendor-defined functionality of an ASIC (application-specific integrated circuit) chip, you can

configure and reconfigure the logic on FPGAs for your specific application. FPGAs are used

in applications where either the cost of developing and fabricating an ASIC is prohibitive, or

the hardware must be reconfigured after being placed into service. The flexible, software-

programmable architecture of FPGAs offer benefits such as high-performance execution of

custom algorithms, precise timing and synchronization, rapid decision making, and

simultaneous execution of parallel tasks. Today, FPGAs appear in such devices as

instruments, consumer electronics, automobiles, aircraft, copy machines, and application-

specific computer hardware. While FPGAs are often used in industrial control products,

FPGA functionality has not previously been made accessible to industrial control engineers.

Defining FPGAs has historically required expertise using HDL programming or complex

design tools used more by hardware design engineers than by control engineers.

With the LabVIEW FPGA Module and NI RIO hardware, you now can use LabVIEW, a

high-level graphical development environment designed specifically for measurement and

control applications, to create PACs that have the customization, flexibility, and high-

performance of FPGAs. Because the LabVIEW FPGA Module configures custom circuitry in

hardware, your system can process and generate synchronized analog and digital signals

rapidly and deterministically. Figure 1 illustrates many of the NI RIO devices that you can

configure using the LabVIEW FPGA Module.

Historically, programming FPGAs has been limited to engineers who have in-depth

knowledge of VHDL or other low-level design tools, which require overcoming a very steep

learning curve. With the LabVIEW FPGA Module, NI has opened FPGA technology to a

broader set of engineers who can now define FPGA logic using LabVIEW graphical

development. Measurement and control engineers can focus primarily on their test and control

application, where their expertise lies, rather than the low-level semantics of transferring logic

into the cells of the chip. The LabVIEW FPGA Module model works because of the tight
