摘要:
特种计算机主板发展的趋势是高密度、一体化、定制化和高可靠性,其使用需求使其必须具有较长的使用寿命以及长期的稳定可供货时间。 目前基于 COME 模块的特种计算机主板设计已成为行业内主流的设计模式之一,而基于COME 模块开发的一体化、定制化主板可以很好的满足特种计算机设计、生产及后续维护、升级等各类需求。 该文介绍了一种基于 COME 模块的特种计算机主板设计方案,在硬件总体设计、电源时序设计、总线接口扩展、PCB 布板、信号完整性、电源完整性及工艺设计等各面作了说明,并介绍了实际调试的步骤、试验验证情况及实际应用情况。 测试结果表明,该主板具有高密度、一体化、高可靠性等特点,可以广泛应于加固笔记本、便携终端、加固一体机等各类特种计算机当中。
Abstract:
The development trend of reinforced computer motherboard is high density,integration,customizationg and reliability. A longservice life and long term stable supply of raw materials are important to reinforced computer motherboard. At present,the design of reinforced computer motherboard based on COME module has become one of the main design modes in the industry. The motherboarddesigned in this way will meet the needs of reinforced computer maintenance and upgrading in the later period. This paper introduces thedesign of motherboard based on COME module and explains the detail design of hardware,power timing,bus interface expansion,layoutand signal integrity. The debugging steps and test verification are also introduced. The test results show that the motherboard has the characteristics of high integration and reliability. This motherboard can be widely used in all kings of products such as reinforcednotebook and portable terminal.
