显示全部楼层
我是用 Astro的, 不過我的認知是跟2樓一樣的,
但是後來進了icc man了一下這兩個command,
---------------------------------------------------------------
set_dont_touch
Sets the dont_touch attribute on cells, nets, references, and
designs in the current design, and on library cells, to prevent
modification or replacement of these objects during optimiza-
tion.
set_dont_touch_placement
Fixes the location of a cell or cluster.
---------------------------------------------------------------
有趣的是don't touch有提到不會replacement & modified
但是fix就沒有提到會不會 modified cell size...
有人要進一步講解一下嗎? |
