encounter时发现很多empty module,感觉有问题,请高手帮忙看下

时间:10-02 整理:3721RD 点击:

我用一个IBM的库进行的综合,得到了网标,结果用encounter读入时,第一步就不对劲(图形窗口总是一条细线和几个字,没有floorplan)。
encounter提示我如下信息:
Found empty module (ADD_UNS_OP).
Found empty module (\**SEQGEN** ).
Found empty module (GTECH_AND2).
Found empty module (GTECH_OR2).
Found empty module (GTECH_BUF).
Found empty module (SELECT_OP).
Found empty module (GTECH_NOT).
Found empty module (GTECH_OR3).
Found empty module (MULT_UNS_OP).
Found empty module (GTECH_OR4).
Found empty module (GTECH_OR5).
Found empty module (ASHR_UNS_UNS_OP).
Found empty module (SUB_UNS_OP).
Found empty module (LT_UNS_OP).
Found empty module (GT_UNS_OP).
Found empty module (NE_UNS_OP).
Found empty module (EQ_UNS_OP).
感觉以上的东西是GTECH的(Synopsys 里不依赖于工艺的那么一个库)。但是我就不懂,我综合时用的明明是我们自己的库,GTECH 是怎么出现的呢?以下就是我综合的synopsys.setup文件:

# Synopsys Cache Directory

set cache_read "~/local/tmp/synopsys_cache"

set cache_write "~/local/tmp/synopsys_cache"

set search_path ". ~/ASIC/aci/sc-x/synopsys"

set hdlin_translate_off_skip_text TRUE

#------ IBMXXnm library

set link_library "* scx3_cmos9sf_rvt_tt_1p2v_25c.db dw_foundation.sldb"

请大侠帮我分析一下是哪里错了?

用特定的standard cell library进行综合,为什么会出现 (ADD_UNS_OP).
(\**SEQGEN** ).(GTECH_AND2).(GTECH_OR2).(GTECH_BUF).(SELECT_OP).
(GTECH_NOT).(GTECH_OR3).(MULT_UNS_OP).(GTECH_OR4).(GTECH_OR5).
(ASHR_UNS_UNS_OP).(SUB_UNS_OP).(LT_UNS_OP).(GT_UNS_OP).(NE_UNS_OP).(EQ_UNS_OP). 这些东西?

求大侠点拨一下,谢谢啊。

netlist 不是 gate level 的

求大侠点拨一下,谢谢啊。

根本没综合好,拜托
