为了支持制造系统的并行设计，开发了一种新的方法论XSPEC和原型工具XFAST。该方法集成了硬件、电气和软件领域的设计工作。该工具将来自不同领域的多个商用设计包集成到一个由该方法统一的系统中。介绍了使用该方法和工具的设计过程。给出了一个简单的设计实例，说明了该过程。本文总结了该工具在两个实际制造系统上的使用。

A NEW METHODOLOGY XSPEC AND PROTOTYPING TOOL XFAST HAVE BEEN DEVELOPED TO SUPPORT THE CONCURRENT DESIGN OF MANUFACTURING SYSTEMS. THE METHODOLOGY INTEGRATES THE DESIGN EFFORTS IN THE HARDWARE, ELECTRICAL, AND SOFTWARE DOMAINS. THE TOOL INTEGRATES SEVERAL COMMERCIALLY AVAILABLE DESIGN PACKAGES FROM DIFFERENT DOMAINS INTO A SINGLE SYSTEM UNIFIED BY THE METHODOLOGY. THE DESIGN PROCEDURE USING THE METHODOLOGY AND TOOL IS PRESENTED. A SIMPLE DESIGN EXAMPLE IS GIVEN WHICH ILLUSTRATES THE PROCEDURE. SUMMARIES OF THE USE OF THE TOOL ON TWO ACTUAL MANUFACTURING SYSTEMS COMPLETES THE PAPER.
