我有一个问题，为一个18F45 K22项目构建一组.ASM文件。所有文件（总共11个）没有错误地组装，直到最近在一个次要编辑会话的中间，系统构建失败了以下消息：-“MPLink 4.49，Link设备数据库版本1.14版权（C）1998—2011 Microchip Technology Inc.错误-找不到S的定义YMBOL在文件'/i2cDelo.O.C.错误中的格式：1Link步骤失败。“所有全局和外部引用都是正确的，相关文件没有参与编辑会话。撤销编辑并没有解决这个问题。更令人困惑的是，复制.ASM文件中的子例程“格式”，它以前被标记为外部，并完全从交叉引用中删除名称，但无法解决生成问题，即使链接器没有报告问题！！！！拆卸列表是不完整的，在两种情况下都是相同的。显然，代码中的某个地方存在问题，但我不知如何诊断它。在试图追根溯源的过程中，我清除并重新加载了MPLAB IDE 8.92，只是为了确保软件没有腐败，是否有人遇到过类似的问题或如何追踪其位置的任何想法？我们将不胜感激。 以上来自于百度翻译 以下为原文 I have a problem with failure to build a group of .asm files for an 18F45K22 project.All the files (11 in total) assemble without errors, and until recently in the middle of a minor editing session, a system build failed with the following message:- "MPLINK 4.49, LinkerDevice Database Version 1.14Copyright (c) 1998-2011 Microchip Technology Inc.Error - could not find definition of symbol 'format' in file './I2Cdisplay.o'.Errors : 1Link step failed."All Global and External references were correct and the files concerned were not involved in the editing session.Undoing the edits did not resolve the problem.Even more confusing, duplicating the subroutine "format" in the .asm file where it was previously marked as External and removing the name entirely from cross referencing did not cure the build problem, even though the linker reported no problems!!!The disassembly listing is incomplete and is identical in both cases. Clearly there is a problem somewhere in the code, but I am at a loss to know how to diagnose it.In trying to chase down the cause I cleared and reloaded MPLAB IDE 8.92- just to make sure there had been no corruption of that software Has anyone experienced a like problem or any ideas as to how to trace its location?Help would be much appreciated.

怎么将ORCAD原理图输出网表？PADS-PCB导入网表？然后PCB输出CAM？ 越详细越好啊。

中国通信网络设备厂商华为正在其部分产品中或采用ASIC以取代Altera的FPGA。这项进展将影响Altera的销售，并可能打击“FPGA正在取代ASIC传统地位”颇具争议性的说法。华为首次采用ASIC到底会对Altera的销售有何影响？FPGA和ASIC之间的拉锯战到底谁的胜算更大？
