请问.25um的Gate:Area是多少? (等效单元门面积?).35um?
我记得:
.25 => 17 左右。
.18 => 10 左右.
可以自己算!
The gate count of a particular library cell corresponds with the function
of the standard gate count of the NAND-gate area in the technology library.
For example, if the NAND-gate cell area is specified as 23 in the technology
library and the flip-flop area is defined as 138, the total gate count of the
flip-flop is 138/23 or 6.
Similarly, the gate count of a design is the area of a design divided by
the gate count of the NAND gate (as defined in the technology library).
This number is the area of the NAND gate. To obtain the area of the design,
use the report_area command in Design Compiler. To find the total gate
count of the design, divide the cell area by the area of the NAND gate.
