Tape-out refers to the delivery of the final design data to the foundry for initial production, which is the most milestone-significant and also the most “costly” phase in the chip design process. 1. Decisions and Verification Before Tape-Out 1. MPW Full Name: Multi-Project Wafer Chinese: 多项目晶圆 Explanation: A method to reduce tape-out costs. It involves … Read more
MDR, XDR, PDR MDR (multi-drug resistant) – Multi-drug Resistance Bacteria are resistant to three or more categories of commonly used antimicrobial drugs. XDR (extensively-drug resistant) – Extensive Drug Resistance Bacteria are resistant to almost all commonly used antimicrobial drugs. PDR (pandrug resistant) – Pan Drug Resistance Bacteria are resistant to all categories of commonly used … Read more

Source: EETOP Blog Author: mervin_li Link: https://blog.eetop.cn/1582944 As we all know, chip projects are complex system engineering tasks, where each link can significantly impact the final delivery. From experience, good project management includes important aspects such as resource allocation, risk assessment, process control, and delivery acceptance. How can these points be achieved independently yet cohesively? … Read more
Printed Circuit Board (PCB) design is a crucial aspect of modern electronic products and serves as the foundation for the development and manufacturing of electronic devices. PCBs are the backbone of electronic products, providing necessary interconnections and support for various components. The PCB design process includes creating layouts to optimize component placement, routing of traces, … Read more
▼Follow our WeChat public account: Hardware Matters▼ Part 01 Introduction Why are Gerber files so important? Gerber files, specifically in the RS-274X format, are the internationally accepted standard format in the PCB manufacturing industry. They serve as the “blueprints” for circuit boards, describing the images of each layer of the circuit board, such as traces, … Read more
This project began around the same time last year, and after a year of “process flow”, we finally received the PDK and digital library 20 days before tape-out. One cannot help but marvel at the efficiency of the team. It took a week to familiarize myself with the process, and the tape-out design was completed … Read more
With the increasing integration of semiconductors, major electronic systems now feature complete system-on-chip designs and custom PCBs. It can be said that even an ordinary PCB can play a significant role, which sets high standards for engineers. This article summarizes the experiences of several experts and lists ten golden rules for PCB design, hoping to … Read more
Despite the increasing integration of semiconductors and the availability of off-the-shelf systems on chip for many applications, there are still many use cases where electronic products require custom PCBs. In one-time development, even a standard PCB can play a very important role. A PCB is the physical platform for design and the most flexible component … Read more
