Chapter 8 and 9 - Becoming a Chip Engineer and the Chips of the Future [Copy link]

Chapter 8 introduces the daily life of chip engineers and some classifications and skill trees of chip engineers.

The book mentions the three virtues of an excellent programmer: laziness, impatience, and arrogance. I think hardware engineers also have this feeling. One of the characteristics of hardware is that there is a cost of experimentation every time. Every time you make a mistake, you have to pay a real price. The book says that the price of a 28NM chip tape-out is tens of millions. So you must be careful and design according to the regulations, and you can't skip steps randomly. I think the more critical ones are sequence, carefulness, and arrogance. You must have high design standards, you can't be lazy and compromise, and you need to carefully consider multiple aspects when designing.

In addition, the book introduces the skill trees of some different chip engineers, such as digital chip design and analog chip design. Analog chips are chips used to process continuous signals existing in nature, and are a powerful tool for humans to communicate with physical quantities in nature. The design of analog chips is very complex and requires deep professional knowledge. If the knowledge is not solid, you can only simulate and randomly scan parameters, which feels quite metaphysical. In terms of analog chips, ADI and TI are relatively leading in the industry. There are also some domestic companies such as Weir Semiconductor, Saint-Bonvie Electronics, and Nanochip Microelectronics. I have also learned about some designs of RF amplifier chips before. The amplifier needs to design some special structures based on different amplifier architectures to achieve wide bandwidth, low energy loss and other characteristics. In principle, it feels difficult. Chip design feels much more complicated than board-level circuit design.

Chapter 9 introduces some chips of the future

Biochip sounds interesting. If you think about it carefully, isn't the organism itself equivalent to an advanced machine? The brain of an organism is equivalent to a CPU, which consumes energy for three meals a day. If we can create a biological robot, such as a pigman with a certain level of primary intelligence that can accept human instructions to work, can screw screws in the factory, do some physical work, or create a beast girl with cat ears that can help with housework and chat with you. The internal composition of organisms is different cells, and each small cell is like a small chip. Genetic materials such as DNA are the instructions in the cell, directing the entire cell to work. The book also mentions quantum chips. This topic was quite popular before, but I don't quite understand the specific principles.

Biochip is a protein chip or gene chip

If this thing becomes popular after artificial intelligence, it will be difficult for humans to have fun.
