PCB、IC封装：设计与仿真分析: 什么是COM/JCOM信道合规技术

Sigrity

在当今这个数以十计/两位数Gbps的数据时代里，工程师的工作越来越不容易，正确地设计并表征系统以符合不断刷新的业内标准搞得大家焦头烂额，不仅要对高速串行链路及其所有损耗进行仿真，还得通过合规测试。雪上加霜的是，大家熟悉的依靠比较不同频域参数（例如插入损耗、回波损耗、串扰等）从而发现设计缺陷的传统合规性检查方法已经过时了！由于没有考虑到不同参数的相互依存性和权衡裕量问题，传统方法容易导致过度设计和成本过高问题。例如，如果一个设计满足插入损耗和串扰指标且有很大裕量，而仅有回波损耗一...

Analog/Custom Design: Virtuosity: In-design Electromigration Analysis - An efficient way to make layouts electrically correct

NamrataM

Shrinking size of ICs with highly complex layouts containing billions of transistors and miles of interconnects....all of this doesn't sound new now. The industry has been pretty fast in adopting advanced node designs and has witnessed various innovations to overcome the challenges faced at this level. One of the challenges is accurate and timely analysis of the effects of electromigration (EM) and IR drop, and faster…

System, PCB, & Package Design : Simulation for a Song: Downloading Models from the Web and Associating with Parts for PSpice Simulation

mrigashira

While on a long drive, I like to sing along; say Eye of the Tiger or Johny B Goode or Sweet Home Alabama (even though I don’t live in Alabama), the music being an active part of the journey, especially when I am just beginning the drive, fresh and eager, looking forward to the trekking and wildlife sightings. Compare this with the schematic design phase. Whistling and nodding while placing the parts: here’s the…
