In multi-voltage design, isolation cells are often used. This article briefly introduces what an iso cell is, how to use an iso cell, when to add an iso cell, and the insertion position of the iso cell. 1. What is an iso cell? An isolation cell, typically used in Power Shutdown (PSO) and Multi-Supply Multi-Voltage … Read more
In chip design, power consumption optimization is a key factor determining chip performance, battery life, heat dissipation, and cost. The sources of power consumption mainly involve power supply voltage, clock frequency, number of devices, and process technology (which affects threshold voltage and leakage current). From the composition of power consumption, we can optimize at different … Read more
Before making a decision, hesitation may be necessary. However, once a decision is made, one should move forward without looking back. ― ― Dazuo Ishikawa Unknowingly, I have written several articles on the topic of SoC power consumption, so let’s summarize them. SoC Design Power Consumption — Introduction SoC Design Power Consumption — Clock Gating … Read more

Hello everyone, I am Da Yi! Today, let’s talk about the techniques for low power design of microcontrollers. The power design of microcontrollers is not only closely related to energy saving and environmental protection but is also particularly important for portable devices powered by batteries. So how can we reduce the power consumption of microcontrollers? … Read more
In the previous article, we introduced methods forsystem-level low power design, such ashardware-software co-design,power management mechanisms, etc. This issue will delve into the core technologies ofarchitecture-level low power design, includingmulti-voltage design (Multi-VDD),dynamic voltage frequency scaling (DVFS),system clock optimization,asynchronous design, andalgorithm optimization. By reasonably dividing power supply areas, dynamically adjusting voltage and frequency, and optimizing clock … Read more
Recently, I have been reading “The Art of Hardware Architecture”, and this blog post is also derived from the content in the book. With the advancement of technology, low-power design has become increasingly important.As a digital front-end designer, let’s take a look at how to reduce power consumption at the RTL level. In large-scale ASIC … Read more
