1. Overview Managing chip voltage drop is crucial for ensuring the stable operation of integrated circuits (IC), involving multiple levels such as the printed circuit board (PCB), packaging, and within the chip itself. Specific recommended metrics vary based on application domain, process node, chip type, etc., but here are some general guidelines and reference metrics: … Read more
As the demand for battery life and energy efficiency in electronic devices continues to rise, low power design has become a critical aspect of chip design. The low power design strategies in DFT (Design For Testability) aim to reduce power consumption during both the testing phase and normal operation while ensuring chip test quality and … Read more
The design of the power grid has a direct impact on chip performance and reliability. It is essential to ensure that the power grid provides sufficient power voltage to all transistors within the cells, allowing the chip to operate normally under all possible conditions within a certain noise tolerance. However, as technology shrinks, the threshold … Read more
Literature from IMEC, published in 2022, focuses on the impact of BSPDN on PPAT.The front end (FEOL) is an active driver of chip power/performance/area (PPA). As scaling approaches the physical limits of semiconductor devices, the back end (BEOL)/middle end (MEOL)/packaging becomes increasingly important for PPA improvements in chips/systems. At 2nm and below, BSPDN back interconnects … Read more

—Knowing and doing are the farthest distances in the world. In previous articles, we introduced the aspects that need to be considered in the front-end architecture and design of SoC, and provided some reference solutions. The last article described the relevant content of UPF, completing the overall plan and UPF. The next step is the … Read more
