Secured Microcontroller Layout Design Importance

In the creative process of Secured Microcontroller Layout Design, there is no tolerance for the slightest mistakes. The creators must carefully consider every detail of the entire layout design without any negligence.

According to statistics, in the total investment in the development of the Secured Microcontroller, the development cost of layout design will account for more than 50%. And as the integration of secured microcontroller becomes higher and higher, the layout design of integrated circuit is more and more difficult.

However, once a Secured Microcontroller is publicly available as a product on the market, its program and data inside the flash and eeprom can be copied. Usually an experienced imperson, as long as the outer casing of the Secured Microcontroller is opened, using a high-resolution camera, according to its structure, the metal connection layer and the semiconductor layer are sequentially photographed one by one, and the integration layer stack-up  and the mask works of each layer of the circuit can be obtained, so that the layout design of the secured microcontroller can also be obtained.

According to the obtained mask works and layout design, the implicator can easily imitate the secured microcontroller without the need of logic diagrams and circuit diagrams.

According to statistics, for a secured microcontroller that is not highly integrated and not too complicated, the time required by the implicator is only one-tenth to one-sixth of the time required by the original developer. The funds spent are only a few thousandth to tens of thousands of the original developer.
