发帖数: 335 | 1 两个以前都用过，其实更喜欢Altium Designer 。但是以前有次用Protel DXP 2004的
时候，做一个BGA器件的PCB布线，那么小的间距在做里面的pad布线时死活都有问题，
后来有个人用OrCAD很快就搞定。
但是我发现OrCAD好像特别笨，不如自己以前用Protel时随心所欲。
请问现在布这种普通的4层6层板，用哪个更方便快捷，Altium Designer 还是OrCAD？
现在国内大家都用哪个？谢谢 |

发帖数: 8 | 2 In terms of being user-friendly, I would vote for Orcad. My judgment is that
Orcad starts on Windows while Allegro carries a lot of Unix Legacy. |

发帖数: 3060 | 3 I have a lot experience with Orcad 10.5 and Altium 10. I don't like Protel.
I'd say Orcad is good for home projects, not so large pcb, need sth quick.
Altium is better on the company level, a lot better functions you can use. |

发帖数: 335 | 4 我以前用Altium的时候感觉确实很方便，布线是很方便 随心所欲。但是那个BGA的过孔
怎么也达不到要求的分辨率和精度，把我给郁闷坏了。
我公司里面用的最基本的OrCAD,那个OrCAD Layout 是在太差了，非常不方便。不知道
Allergo用起来方便吗？ |

发帖数: 577 | 5 My ORCAD's version 10.3. When I try to open it, it always requires my
company's server. If I stay offline, then I cannot open it. What's the
problem? Is there anybody experiencing this issue before? |

发帖数: 197 | 7 orcad只是schematic，或许你说的是layout plus，好像现在layout都不卖了，cadence
只推allegro，据说是最牛x 的PCB 软件之一，我们这里都设计低速的电路，所以没有
特别的要求 |
|
d****o
发帖数: 1112 | 8 orcad是最简单好用的schematics tool，cadence买它就是为了灭了它
搞得现在一堆bug丫也不修，全力推他的concept
allegro是最牛的PCB软件了，不过现在布线这种力气活都外包了吧

发帖数: 3060 | 9 很简单啊。copy一个已有类似元件。看datasheet怎么说然后编辑所有管脚和footprint
就可以了。
什么叫执行你需要的功能？如果你需要做subcircuit用来仿真的话直接看orcad教程里
会说。 |

发帖数: 81 | 10 看文档啊，创建symbol。要仿真的话不要忘了在Option里面添加.lib。.lib需要从元件
所在网页上下载，然后用Orcad自带工具生成。 |

Orcad + Allegro is one of the most powerful industry-level design suites,
not merely for home project.
I'd say Altium designer is a good choice because it is easy to learn. |

发帖数: 3060 | 12 我用orcad是很老的10.5，现在的版本不会用。但是呆家里设计点小东西很足够。 |

发帖数: 24265 | 13 都是用的orcad默认配置，最后厂家没有指出错误，制版也顺利，因为那个灰色的东西
没有使用
请教orcad PCB软件里2个，一个是layout，另一个是editor
这两个同时在orcad软件包里，哪一个比较先进或将被另一个取代？ |
|
d****o
发帖数: 1112 | 14 这本不行吧
现在业界流行的是OrCAD or conceptHDL做schematics, Allegro做PCB,hyperlynx做sim
ulation
用orcad layout的是少而又少
PowerPCB也比这个流行吧 |
|
i*****t
发帖数: 24265 | 15 这个是默认设置下的power plane颜色，虽然碰一起了，但是做出来的板子却没问题，
因为是双层板
顺便问下，orcad的layout是不是过时了，那个orcad 的PCB editor是干嘛的？哪个才
是流行的？ |

发帖数: 77 | 37 我想仿真一个器件（两端输出的），其电阻是随频率变化的
比如R=300f+20f^2
但是，我又不希望带来热噪音，所以不能用一般的R器件在Pspice里
我一般用G器件，也就是那个电压转变为电流的spice器件
一般如果是定值的电阻r，我把G器件的gain设置为1/r，然后做个简单的连接即可
但现在是变阻值情况，不懂得怎么设置，怎么给器件写code
大牛能否有人帮忙一下！
谢谢了！ |
