DC综合怎么处理特别大的模块

好像有top-down和bottom-up两种方式，具体应该怎么处理?例如bottom-up，是先综合下层模块，然后上层模块综合的时候直接调用下层综合后的网表，并且将其设置为dont-touch类型，再对上层模块进行综合吗?
多谢指教！

对， 下层子模块存成ddc，用dc hier flow，子模块创建ilm ， etm view给top ，

呃，这几个词都完全不懂……请问有没有啥资料讲这个的?看来需要系统学一下啊……

去synopsis 网站下载 dc RM scripts ， hier flow即可，

谢谢！

您好，我目前在综合子模块 生成了ddc 然后再顶层调用了。 一个综合了两个字模块ddc，第一个导进去没问题 第二个报错误了。

不知道您遇见过这个问题没有。 说我的db库的名字有问题 我感觉没问题啊而且第一个ddc已经read成功了。应该没啥问题了啊。

小编，您好。 我最近在研究调用子模块综合，我有两个子模块需要综合，都综合成了ddc。然后顶层直接read_flie ***.ddc
第一个ddc读入没问题，第二个出现错误。log如下

不好意思，这个问题我也不太清楚，好久不用DC了……

不知道您是否还记得你当时bottom——up的时候。 a.vb.vc.vd.ve.vtop.v我先综合a.vb.v 综合完之后 出一个a.ddcb.ddc然后再次综合，这时读入 c.vd.ve.v top.v a.ddcb.ddc 但此时需要将a.ddcb.ddc设置为dont_touch。但是貌似上网看有什么端口。ilm等等这些东西。 我也没找到资料下载哈，，，

我把ddc岔开导入到dc中，就解决了这个问题，不知道为啥就没了 哎。

您好，求bottom_up编译方式的有关资料，谢谢
