本文介绍了一个用于多层印制板布线设计的自动布线程序。布线采用的基本算法是迷路法。在分线、分层、定顺序、迷路等过程中采取了相应的措施以提高布线率和改善布线性能。 本系统具有广泛的适应性,对满足工程上各种规范要求具有较大的灵活性,还提供了各种必要的人工干预手段。最后通过数控程序提供较完整的数控数据输出,实现印制板的自动布线和印制板生产中的照相、钻孔、测板等自动化。 本系统已经在实际中使用。通过大量使用表明,布线速度快,布通率高,用户对布线质量较满意。
This article describes an automated routing program for multi-layer PCB layout design. The basic algorithm used in wiring is lost. In the line, stratification, order, get lost and other processes taken to improve the wiring rate and improve wiring performance. The system has a wide range of adaptability, to meet the engineering requirements of a variety of specifications with greater flexibility, but also provides a variety of necessary manual intervention. Finally, the NC program provides a more complete NC data output, automatic printing of printed circuit boards and photographic production in PCB production, drilling, board and other automation. This system has been used in practice. Through a large number of use shows that the wiring speed, the high pass rate, the user is more satisfied with the quality of the wiring.
