请教brd 转hyp问题

wowo1215

我用的是Hyperlynx 8.0版，点File-->New Board(Run PCB Translator) 可以把brd转成hyp，但是会丢失信息，有的net变成unroute net了。 我如果用Allegro的extract 命令行，生成了9个txt文件＋1个a_b文件，就是没有hyp文件。
请大侠指教啊。

From my personal experiences,
I do NOT  really trust the HyperLynx built-in automatic converter (directly *.brd to *.hyp). So, when the converting fails or show error, try not  using HyperLynx built-in automatically converting with Allegro *.brd file, manually use command line (by using extracta.exe) to create *.a_c file, then loading *.a_c file to convert to *.hyp.

You may try this way.

7 p7 j; m+ W* B$ z/ t& Yassuming:
(1) convert "R0A.brd" to "R0A.hyp"
) Y) f# [! X0 F4 |3 _(2) You may find "extracta.exe" in "X:\cadence\spb_16.2\tools\pcb\bin" directory
(3) you may find "hyp.txt" in HyperLynx installed directory.

#1: execute  the following command in XP command prompt
->extracta.exe R0A.brd hyp.txt R0A.a_l R0A.a_o R0A.a_c

It will generate three Allegro ascii files:
(1) Component & connectivity data (a_c)  => we need this ONLY.
(2) Layout data (a_l)

I hope it will help !

感谢Ilovechina的详细解答。
实际上，我如果用Allegro的extract 命令行，生成了9个txt文件＋1个a_b文件，我把这个a_b文件用hyperlynx转换跟直接转brd结果是一样的，还是好多net的信息会丢掉，尤其是小的net或者表层的thermal relief。 不知道有没有什么好的办法？

brd还是用allegro的sq比较好吧！

Do you really execute this same command word by word except for file name ??

  u1 E( }9 p  ]! e* m" m; }2 Eif you execute the same command, except for file name, I do not see how it could create  nine txt file, plus *.a_b file (what is that ??)
. c+ e. E2 Q4 A& q- ?# T6 `
% E" l$ P: c  e- cwhy not copy your brd file + hyp.txt to allegro extracta.exe directory ("X:\cadence\spb_16.2\tools\pcb\bin") and execute #1 command to see if it create those three files or not ?? (I bet it will unless there is error at brd file)

The Cadence Allegro(extracta.exe) must generate those *.a_c, *.a_l and *.a_o files for interfacing with HyperLynx.

And  I think you are using SPB 15.x version that are still with "extract.exe". New SPB 16.x is with "extracta.exe". They should be same as function wise. I  have another PC still installed with spb 15.5 ("extract.exe") and got the same result as SPB 16.2 ("extracta.exe")

再次感谢Ilovechina的详细解释。
% M2 |0 `6 J8 Y! P, {7 o. G由于我现在用的Hyperlynx的版本是8.0的，其hyp.txt文件已经升级成control_hyp.txt了，输出文件也由原来的三个增加到了十个（9个txt文件＋1个a_b文件），对板子的描述也更详细了。而这个a_b文件就相当于之前的a_c文件，确实可以从hyperlynx中直接转成.hyp文件。但是，就是转完以后会有net（或者其中一段）被漏掉。
不知道ilovechina手头上有没有8.0版的hyper可以试一下。或者如果你有老版的，也可以发上来，我装上再试试。

Someone uploaded this brd file on this web a while ago. I just use this as example.  It can be converted to Hyperlynx (v8.0) boardsim file *.hyp. The attachment is the brd & hyp.

我又从网上找了一块双层板，用Hyperlynx8.0直接就可以转成Hyp格式，没有出现什么问题。但是用来转我的板子（只有6层）就出问题了。哎，郁闷了。。。

楼主辛苦喽，谢谢分享，加油啊，顶一个 bjbdf466zgl

如果只是做反射分析,一些不重要的线unroute应该是没有问题的.

请问，您的allegro文件，是怎么转成hyp文件的？{:soso_e122:}
