用memory compiler综合出来的结果,面积大得惊人?!

eel

我用memory compiler综合一个192*8bit的SRAM,这应该是很小的
/ m2 [5 {( a" Q" I* c
用DC调用memory compiler产生的DB文件,综合出来的结果,用report_area面积大得惊人?!
! f, @$ M  x; P3 b( b- ~
+ ]* D% c  V5 C2 Z$ q- h4 W达到3mm*3mm,这个太不正常了吧,连线占的面积太大了,99%以上是连线所占的面积?
+ f( ?% L! }& i+ a
- y/ p4 Q& X6 Z/ ?" c3 a请教各位,有遇到过这样的问题吗?
