Description

一种ODB++文件修改方法、装置及可读存储介质 技术领域
本发明涉及电源完整性仿真技术领域,尤其涉及一种的ODB++文件修改方法、装置及可读存储介质。
背景技术
ODB++是一种可扩展的ASCII格式,它可在单个数据库中保存PCB制造和装配所必需的全部工程数据。单个文件即可包含图形、钻孔信息、布线、元件、网表、规格、绘图、工程处理定义、报表功能、ECO和DFM结果等。操作人员可以改进和改正DFM来更新他们的原始CAD数据库,并设法在设计达到装配阶段之前识别出所有的布线问题。ODB++是一种双向格式,允许数据上行和下传。ODB++数据库类似于大多数CAD系统的数据库。一旦数据以ASCII形式到达线路板车间,制作者就可实施增值的流程操作,如蚀刻补偿、面板成像及输出钻孔、布线和照相等。
电源完整性(PI,Power Integrity)就是为板级系统提供一个稳定可靠的电源分配系统(PDS)。实质上是要使系统在工作时,电源、地噪声得到有效的控制,在一个很宽的频带范围内为芯片提供充足的能量,并充分抑制芯片工作时所引起的电压波动、辐射及串扰。
电源完整性研究的内容:电源完整性仿真的内容很多,但主要的几个方面如下:
1:板级电源通道阻抗仿真分析,在充分利用平面电容的基础上,通过仿真分析确定旁路电容的数量、种类、位置等,以确保板级电源通道阻抗满足器件稳定工作要求。
2:板级直流压降仿真分析,确保板级电源通道满足器件的压降限制要求。
3:板级谐振分析,避免板级谐振对电源质量及EMI的致命影响等。
市面上电源完整性仿真设计软件很多。但由于商业目的及保密的原因。不同公司EDA软件间的PCB设计文件很难实现相互完美的转化,现实的情况是即使某EDA软件提供了转换到其它EDA厂商能识别的PCB设计文件软件转换接口,但在转换的过程中总存在这样或那样不完美的地方,例如转换了的文件经常会出现缺少了铜皮、过孔或丝印需要重新调整或元件信息缺少等诸多问题。
为了解决不同EDA厂商加工文件的问题及方便加工生产方面,出现了ODB++的标准(它是偏向于制造的一种格式),由于这个文件作为一个标准的公开格式,其可以作为现在市面上的所有EDA软件一个输出的接口标准。不同EDA软件导入ODB++后铜皮及过孔缺少等问题就能解决,但由于它是一个偏于PCB加工文件的标准,元件的电属性(如电容的模型名字、电容封装名)在调过来后由于不同PCB设计软件的差异性及设计都的不规范可能会有问题,这种情况下如对调入的ODB++文件再要修改其电属性,就没有在原EDA软件中修改原PCB文件方便或根本就可行。
而PI仿真时需要调入相应的PCB设计文件,在某一个EDA软件商的PI仿真平台调入其它EDA软件的厂商的文件时,除了可能出现的缺少了铜皮、过孔等问题外,电容、电阻或电感的值或封装会调不过来或格式不对(如:客户提供的PCB设计文件由于内部定义不规范等,转到PI平台后,默认的模型可能是同一个名字---如封装外形的名字,而实际的元件库模型不同),或元件的模型名字不可识别,这就需要后期使用手工处理,处理过程可以根据电容的实际仿真模型或对应的值分别处理,电容较多时这个过程会非常耗时且易出错。

如图1所示,一种ODB++文件修改方法,应用于电源完整性仿真,其包括以下步骤:
步骤1:获取PCB文件中或独立提供的第三方的BOM列表,该列表中包含元件的标号列、元件的封装列以及元件的数值列;
步骤2:将BOM列表中的元件的封装列与元件的数值列成元件的模型库名称列,并将此列覆盖原来的封装列形成更新列表文件;

具体实施例
以CADENCE厂商的Sigrity PI仿真平台为例(适用于其它EDA软件商的PI仿真平台),其它软件PCB设计工具输出标准ODB++的文件。根据PCB文件中或独立提供的第三方的BOM信息内容主要为三列:元件的标号、封装相关信息的名字、数值(此列可缺)),为了便于后面在PI平台中辩认不同的电容把上图中的封装名与值合在一起,后同的程序会以这三列为处理对象。最后把数所整理成,命名为reflist.txt文件。
使用程序把个表与odb++文件中子目录 (…\layers\comp_+_top\…\layers\comp_+_bot\)下的components文件进行处理。最后分别通过程序处理bom表及components文件,修改components文件相应的内容并何存即可。具体修改过程如下:
(1)打开reflist文件;
(2)逐行读取reflist的文件;
(3)处理读取的行的值给赋给三个变量$ref、$modid、$value
如$ref与$modid的值同时存在
逐区块读取..\layers\comp_+_top\子目录下的components文件,
