output: s1238_delay_top schematic,s1238_delay_top layout
¡¡
1)create s1238_delay_top schematic
-create a folder ".../s1238/s1238_delay_top"
-generate s1238_delay symbol from s1238_delay schematic
-create s1238_delay_top schematic with s1238_delay symbol
-add property to the s1238_delay symbol
-generate viewpoint for this s1238_delay_top schematic
¡¡
2)generate s1238_delay_top layout
-create s1238_delay_top layout cell
(Because auto route process only routes one pair of GND-VDD, we need to manually route the other two pairs of GND-VDD. The width of path connecting GND and VDD is"50". 6*6 via is also needed to connect mental1 layer and mental2 layer during the above step. )
-save s1238_delay_top layout cell
(note: In some figures of last three steps, s1238_delay_top_layout2 is showed. Actually it is the same as s1238_delay_top_layout.)
