Summary form only given. Application Specific Integrated Circuit (ASIC) design requirements within Boeing span the range of highly reliable parts for use in commercial airplanes to radiation hardened parts required for space applications. The author discusses the tools and infrastructure in place to meet the diverse ASIC development requirements. The top down design process controls and captures the design from conception, through system level modeling, to VHDL design entry, finishing with physical design producing the foundry ready database. Foundry independence and flexibility are accomplished through synthesis and also supported by physical design tools that give better control and choice in library selection. Low volume production requirements and foundry accesses that are becoming scarcer require complete foundry independence. Physical design flexibility is achieved through the use of a silicon compiler tool that provides not only foundry retargetability but also cell development capability for creation and additions of library functions. Critical timing verifications and optimization are also supported as part of the layout options.
只提供摘要形式。波音公司的专用集成电路(ASIC)设计要求涵盖商用飞机中使用的高可靠性部件到空间应用所需的辐射硬化部件。作者讨论了适当的工具和基础设施,以满足不同的ASIC开发需求。自顶向下的设计过程控制和捕获设计,从概念,通过系统级建模,到VHDL设计入口,最后与物理设计产生铸造就绪数据库。铸造厂的独立性和灵活性是通过合成来实现的,并且还得到了物理设计工具的支持,这些工具在库的选择中提供了更好的控制和选择。小批量生产需求和越来越少的代工厂通道要求完全独立的代工厂。物理设计的灵活性是通过使用硅编译器工具来实现的,该编译器不仅提供了代工可重定向性,还提供了创建和添加库功能的单元开发能力。关键的时间验证和优化也支持作为布局选项的一部分。
