We have explained in depth the essence of this magic and how it can help simulation engineers more efficiently complete chanting and casting spells at different stages of analog chip design, based on common EDA tool characteristics and principles, from a computational perspective.
Episode 2: Digital IC
If we want to record a sound, the method of simulating a signal is to record all the sound information using a continuously changing electromagnetic wave or voltage signal. According to certain rules, it is converted into a string of binary numbers 0 and 1, and then represented by signals in two states, which is called a digital signal.
The chips used to process digital signals are digital chips, such as common CPUs and GPUs.
When the sound increases or decreases, the analog signal will change accordingly, so the analog signal has countless states. The subtle differences between states require human experience and judgment, with a somewhat metaphysical element.
And digital signals always have only two states: 0 and 1. The conversion of signals strictly follows logical relationships, and an output corresponds to a unique and determined result. The program executes completely according to the output instructions, which is scientific.
The design goal of digital IC design engineers is to pursue a perfect balance among the three indicators of PPA (Power, Performance, and Area).
How to play with this science?
This is an art form.
Today, we will discuss from the perspectives of resource requirements, parallel features, and data sensitivity how to utilize the characteristics of different EDA tools in various stages of digital chip design to significantly improve the design and development efficiency of digital chips.
In line with analog chips, this article still starts from a computational perspective. As for scheduling/management/data/collaboration/CAD and other perspectives, they will be reflected in subsequent articles (such as the third episode)
Compared to analog, there are more scenarios where digital chips require EDA tools, and IC engineers are naturally closer to the use of computers. But just like "", R&D personnel who are only responsible for a certain task may not care or only understand their own part, and IT may have limited knowledge of the business and may not necessarily be clear. Unless there is a big man in charge, most companies' daily life is mainly based on empiricism.

Is the chip no longer fragrant

2023-01-12

The latest data shows that South Korea's chip production fell for the fourth consecutive month in November last year, with a year-on-year decline of 15%, marking the largest decline since 2009. According to an analysis by UBS, chip inventory is at its highest level in over a decade. From "chip shortage" to "destocking", in just two years, the global semiconductor industry has undergone a "sudden change".

Starting mass production of domestically produced 4-nanometer chips? It is actually a misreading. People's branch likes, Xiaomi 11 after-sales upgrade

2023-01-12

Do you see any news that domestic 4-nanometer chips are starting mass production? Industry interpretation # After a look, it's almost like Zhang Guanli Dai. It is a good thing for everyone to pay attention to the self-developed ability of domestic high-end chips, but it cannot be overemphasized. Previously, the Huawei Mate40 series phones were equipped with the flagship 4-nanometer processor Kirin 9000, which exceeded the production time of Qualcomm and MediaTek. But we still need to recognize that chip design and independent mass production are two different things. Our strong investment in these high-precision and cutting-edge technologies over the years is already on the way, and we look forward to the independent mass production of self-developed high-end chips together! Huawei and other domestic technology leading enterprises are working together to overcome difficulties at the right time! The iteration between technology development and mass production is indispensable. Today, we saw news that the iPhone in the 16 series may cancel the Lingdong Island, which also means that the current solution is a transitional stage of compromise, and domestic mobile phone manufacturers have started the application of front camera heads under the screen. Especially for the next generation iPhone, it will add domestic enterprise BOE to the supply chain system of high-end screens, which is another turning point for domestic technology companies to focus on high-end innovative research and development. At the same time, there has been no response regarding the recent issue with the Lingdong Island screen on the iPhone 14 Pro. Compared to domestic mobile phone manufacturers, their after-sales service guarantee measures for users are more comprehensive and timely. Previously, People's Daily reported on the service measures of domestic mobile phone manufacturers, among which it is worth noting that Xiaomi has updated the service guarantee of Xiaomi 11 series mobile phones to 3 years. This means that even if users of Xiaomi 11 series phones have been using them for over a year, they can still enjoy the guarantee service measures within 3 years. It is not difficult to see the importance that enterprises attach to user feedback during this service upgrade. It will further increase the trust and loyalty of Rice noodles, and at the same time, it will also help improve the brand influence. For users of this series of mobile phones, this is very favorable and good news, which can make them more confident and comfortable during the use of the phone. For manufacturers, this is also an opportunity to improve brand awareness and competitiveness. It must be said that Xiaomi's actions are truly generous. The products that had already been insured could have been ignored, but still received upgrade service measures, which is probably a reflection of the value that Xiaomi has grown into the world's third largest smartphone manufacturer over the years. Becoming Apple's biggest competitor at present, domestic smartphones are also receiving increasing support from users. In addition to product advantages, after-sales service advantages are also a bonus.
