allegro导出3D文件(emn和emp)时的问题!
谢谢!
急等回答,谢谢了!
没人知道吗?
我也想知道
有关DFA_BOUND_TOP的信息:http://www.cadence.com/Community/forums/p/10684/11609.aspx,英文不大好,等待大侠翻译一下,呵呵
请教一下,在导出emn和emp文件时,proe读取元器件的长宽高信息是从palce bound top/bottom层吗?
是的……

Place_Bound_Top
Used to ensure you don’t place components on top of each without getting a DRC. This boundary
normally defines the component area which may or may not include pins of surface mount devices.
This boundary can also be assigned a component high to be verified at the board level and checked
to the Package_Keepout_Top boundaries or any other special component clearances. If this boundary
does not exist than it will be automatically created based on the Assembly_Top outline and the outer
extents of the component pins. This boundary can only be defined at the symbol level (.dra).
Place_Bound_Top用于确保你不会在其他器件的顶部放置器件,否则报DRC。这个功能定义了器件所占区域,包括表贴器件的pins(有些不包括)。这个功能也能用来定义板级检验时的器件高度,和检查Package_Keepout_Top或其他特殊器件间距。如果这个功能不存在,它将依照Assembly_Top的边框和器件pins的向外扩展,自动创建。这个功能只能在symbol级定义(.dra)。
Dfa_Bound_Top
Used by the Real Time Design for Assembly (DFA) Analysis to check clearances between components
driven by a Spreadsheet based matrix of components. This boundary normally or can be different then
the traditional Place_Bound_Top boundary and it may include pins of surface mount devices.
If this boundary does not exist than the DFA checks default to using the Place_Bound_Top boundary.
This boundary can only be defined at the symbol level (.dra).
Dfa_Bound_Top
在实时设计中,在器件阵列的数据表驱动下,用它在装配(DFA)分析中检查器件间距。该功能(指定所占区域)可以相同,或不同于传统的Place_Bound_Top功能,即可能包含表贴器件的pins。如果这个功能不存在,则DFA检查就默认的使用Place_Bound_Top功能(来代替)。这个功能只能在symbol级定义(.dra)。
Package_Keepout_Top
Used to ensure you don’t violate placement keepout areas or high restricted area in a design.
This boundary can only be defined at the board level (.brd) and cannot be added to the
symbol level (.dra) unless it is part of a Mechanical Symbol (.bsm)
Package_Keepout_Top
用于确保在设计中,你不会在keepout区或高度受限区,非法放置器件。这个功能只能在board级(.brd)定义,不能添加到symbol级(.dra),除非他是机械symbol(.bsm)的一部分。
草草试着翻译了一下,大家将就看吧

非常感谢您的翻译,谢谢!
还是那个问题还问一下,如果说我在brd文件中把一个器件的place bound top/bottom删除,直留dfa bound top/bottom在,那么导出的3d文件在读取器件长宽时是读取dfa bound top/bottom的数据吗?
我不是权威,你还是自己在多看看
好的,谢谢!
问下,你这些个英文是从哪里来得。?谢谢
