The incident at the door of the dormitory was just an episode, and when he arrived at the destination, Wang Anran wanted to invite the master to a meal to express his gratitude, but he was politely refused, and during the chat, he knew that the master's surname was Wu Mingbin, and he was a retired soldier.

"Haha, my hands are itchy, try to see if the old arms and legs are rusty. ”

Wu Bin was very hearty, and revealed the matter lightly, in his words, Wang Anran felt that he was a person with a story, but after all, he didn't have any friendship, and it was not easy to ask deeply.

Back at the rental house, he didn't take the past to heart, in his previous life, his feelings for Shan Lei had long been put down, and now, what he wanted to do more was the chip.

At this time, the foreign chip industry is changing with each passing day, step by step, and it is almost impossible to wait for those giants to complete the patent barrier and break through the cage.

In 1993, this was a huge opportunity for Wang Anran, Intel, AMD is still exploring in the field of multimedia, if they can set up a patent barrier for these giants in the field of multimedia, in exchange for licensing, they may get tickets to enter the market.

Wang Anran needs a stepping stone, along the way, he thought very clearly, he can't get x86 authorization, and he can't do microcomputer CPU, of course, you can do an open CPU with reduced instructions, but if there is no support from accessory manufacturers and ecology, it is basically equivalent to playing by yourself, and there is no point.

This is also the rule of the chip industry, why so many manufacturers, chip companies, so keen on the formulation of standards, is also the reason.

At the moment, we can only make accessories.

As long as it is a computer, it must be indispensable to have a graphics card, and if I am not mistaken, there is no real 3D display chip in the world today.

The Voodoo graphics card, which almost dominated the country at that time, was designed by 3DFX two years later.

In addition to the graphical interface specification API, in addition to the self-developed by their respective manufacturers, the more influential is the OpenGL 1.0 graphical interface specification launched by SGL in July 1992.

As soon as open GL was launched a year ago, it was sought after by major hardware manufacturers, even in 2019, the openGL interface is also an important API for major game companies to develop engines, and the vitality is conceivable, even Microsoft, after launching its own direct 3D API, it is also compatible with openGL in the win system.

Wang Anran was at AMD, and once led the development of APU, and in fact, his understanding of OpenGL was even more proficient than that of the original designer.

Even if you design a set of 3D auxiliary chips now, there is no problem, but the premise is to have advanced development tools, that is, chip design software, simulation software, such as EDA software, TCAD, Solido Design, etc., otherwise, chips containing millions of transistors, hand-drawn by hand, that is a massive amount of engineering, not to mention the follow-up simulation test, the chip on paper is not simulated.

Wang Anran learned that such software, foreign countries are strictly blocked, even after 2000, some domestic chips can buy these software at a high price, but the buy is also a seriously castrated version, but even so, it is also a domestic advanced existence, in fact, these chip design software companies, the purpose is to maintain two to three generations of advantages in China.

And China, which has experienced twenty or thirty years of chip development, has not developed its own chip design software.

There are many reasons, chip design software is highly related to chip hardware, in the process of hardware development constantly update technology, according to Wang Anran learned that one of the three major EDA software cadence, every two weeks to update the technical database, it is conceivable that there is no soil for the development of chip design software in China.

Such a situation must change, because of the arrival of Wang Anran, the biggest short-board chip manufacturing, in Wang Anran, has become the biggest advantage.

At AMD, Wang Anran personally participated in and led the development of a number of CPUs, APUs and chipsets, one of the important contents of which is to conduct technical public relations with foundries, the purpose is how to reflect the design drawings on the chip, and make the chip meet the technical parameters expected by the design.

Therefore, Wang Anran is well aware of the process of chip manufacturing development over the past few decades.

In 1993, the world's most advanced microprocessor Intel Pentium used the most advanced 800-nanometer manufacturing process at this time, while TSMC, the chip foundry on the other side of the strait, used the most advanced process at this time was 1 micron.

The process is different, the chip design is also different, and the register, cache and logic structure are also different in the structure of the transistor, resulting in an exponential increase in the complexity of the software, which is also a natural threshold, and ordinary companies cannot enter the door at all.

Plus to go through the design_validation_modification_validation...... Ongoing process, in which the amount of money that needs to be invested is even more massive.

These are not problems for Wang Anran, Wang Anran thought twice and decided to design a set of object-oriented chip design software, the main point of which is to design according to requirements.

For example, it is necessary to design a set of scientific computing units, which need to input the demand indicators of scientific computing into the computer, as well as the relevant chip parameter settings, and the software can generate the optimal chip structure to achieve the established intention at the physical level.

This can greatly reduce the difficulty of design, but greatly increase the difficulty of the software.

First of all, the software needs to build a model of more than 300 various logic gates, set the uplink and downlink voltages of transistor operation, and the upper layer identification.

Even so, with the help of the mature technology accumulation in the previous life, Wang Anran is sure to make a simple version of the EAD software within three months, of course, it cannot be compared with the EAD software used in the later life, and the degree of intelligence is far less.

It only includes the logic gate circuit design under the existing technical conditions, as well as a simple loop test.

But even so, Wang Anran can confirm that it is the most advanced EAD software integration today.

The so-called sharpening of knives does not mistake woodcutters, but no matter how good the plan is, how to implement it is a problem.

Wang Anran suddenly thought of one thing, when the students of Qingdao University had free computers, there was a 390 minicomputer produced by IBM in 1990 in the computer room of the campus, providing IBM's special Turing operating system.

Of course, what Wang Anran values most is the good performance of the 390 comparable to the Pentium IV, as well as the complete C language compiler.

His computer card has been handed in long before graduation, but it is difficult for Wang Anran, his friend Jia Guofang from college, to submit to the graduate school of this school, and his computer card can be borrowed.

Prior to this, Wang Anran spent a night sorting out the various chip technologies in his memory, and formulating the specific structural framework of the software.
