Re: customized?
Dear Dude,
in a simple way, the standard cell mask can be altered according to the need
or
Standard cell based is also called as CBIC,
The standard-cell areas (also called flexible blocks) in a CBIC are built of rows of standard cells—like a wall built of bricks.
The standard-cell areas may be used in combination with larger predesigned cells, perhaps microcontrollers or even microprocessors, known as megacells .
The ASIC designer defines only the placement of the standard cells and the interconnect in a CBIC.
However, the standard cells can be placed anywhere on the silicon; this means that all the mask layers of a CBIC are customized and are unique to a particular customer.
The advantage of CBICs is that designers save time, money, and reduce risk by using a predesigned, pretested, and precharacterized standard-cell library
