SPICE与spectre的区别与联系

有过类似帖子，你先查下看看再问

就像android系统和小米系统的关系

菜鸟喜欢图形界面as always.....hspice更高效

spectre 比HSPICE 好用的多；虽然，做模拟电路偶尔用用hspice，但射频方面几乎都是spectreRF 而非hspiceRF。

这个比喻到位，哈哈

Spectre is slow, but it is user-friendly especially for teamwork. So, it really depends. I once simultaneously used hspice, spectre and ADS for one project.

spectre带上aps比hsipce不知快了多少倍
hspice收敛性严重不如spectre
电路上了规模，hspice基本就是废物，比如大到一个soc的top integration co-sim

我是新人，不过我感觉可能各有各的有点和确定吧，呵呵，可能我用的太少了吧，体会不到这些差异！

受教了，多谢各位！

HSPICE早年版本不太好现在改进很大，不觉得速度和收敛性比较差别还有那么明显，设置不同差别当然很大，多线程多处理器使用都不再是问题。HSPICE本来没有设计用来做系统级模拟，synopsys有其它工具（比如finsim，xa等）做那些事，这么比也不觉得公平。

Spectre内建了许多功能尤其在RF模拟时，的确比较方便。HspiceRF没用过，不清楚。

Hspice速度快，稳定性好，精度不如spectre
Spectre慢，功能强大，设置方便。
新手推荐spectre

不要误导别人

It is unfair for synopsys if multi-thread servers are considered.... maybe you are working for CDN? Sorry, I am neutral at any circumstance. I mean it depends and I don't want to mislead anybody.

We engineers have too many things to do. I think the ability to choose process, simulator and thus the cost, performance, yield, is definitely most important.
