Anex made full preparations for the production and manufacturing of supercomputing servers as early as last March.
At the same time of putting forward the production plan, the R &；
D and production of its core chips have been put on the agenda accordingly. There are seven steps to design the front-end of the chip:
First of all, the chip design needs to understand and analyze the needs of users, because the chip specification, like the function list, is the design requirements that customers put forward to the chip design company, including the specific function and performance requirements that the chip needs to meet.
Anex electronics can scientifically formulate specific schemes that can realize the specifications according to the specification requirements put forward by customers, and then come up with design solutions and specific implementation architectures to divide module functions.
During the circuit design of the chip, many files can be output, such as "chip function specification", "chip architecture specification", "register transfer design", etc. after the chip architecture design, the chip engineer can start editing the logic code. Today, with the rapid development of science and technology, tools have evolved so that there is no need to write out the circuit directly. This process can be completed by programming language. For example, this is done using the Programming Language Verilog HDL.
You may not understand what Verilog HDL means, but it will play a great role in the next step. After completing the circuit design, the code in our hands is a hardware description language, that is, HDL. This language is used to describe RTL circuits (register transfer level). Generally speaking, it can also be imagined as describing circuit design in the form of code.
This link is to test and analyze the completeness of key circuit specifications, verify the correctness of coding design, and whether various functions can be realized, and then optimize and adjust to see whether the design accurately meets all the requirements in the specifications. If the specification requirements are not met, the design and coding need to be modified. Design verification is an iterative process until the verification results show that the specifications and standards are fully met.
Convert RTL to netlist and then to GDS (physical layout). This is the complete layout and wiring diagram. Of course, it needs to be checked and modified synchronously.
At the same time that the foundry processes and manufactures the chips, we also need to prepare the corresponding "hardware" equipment to complete the design and production of the supercomputing server motherboard and control board, which is a key step in the birth of the supercomputing server.
What is a motherboard? Motherboard, also known as motherboard, system board, or motherboard, is one of the most basic components of a computer. The main board is generally a rectangular circuit board, which is installed with the main circuit system of the computer, generally including BIOS chip, i/o control chip, keyboard and panel control switch interface, indicator connector, expansion slot, DC power supply connector of the main board and card, etc.
So what is a dashboard? Control board is also a kind of circuit board. Although its application scope is not as wide as that of circuit board, it is more intelligent and automatic than that of ordinary circuit board. Simply put, a circuit board that can play a controlling role can be called a control board. From automatic production equipment of manufacturers to toy remote control cars for children, control boards are used inside.
After the production of main board and control board is completed, the production of mining machine can enter the next process.
After going through the three stages of mask, hybrid bonding and bumping, Anex ushered in the process of system unsealing. "Everything is ready, only 'chips' are missing.". The main board and control board have been made in the preliminary preparation. At this time node, the chassis and power supply can also be made. In early March, the company received the nano chip, and then sent it to the processing plant for the final packaging test.
In the last cycle, Anex is mainly responsible for the package phase, that is, the assembly of all hardware. The third phase of supercomputing server will come out soon, and will be presented to users through layer upon layer tests in the future.
This equipment has established more perfect delivery and after-sales guarantee, and shortened the delivery cycle to April. Accuracy and stability are the core competitiveness of et7-4u.
