PCB设计团队如何在布线之前发现并解决信号完整性问题

By Sigrity | 14 Dec 2018

PCB设计团队面临的一个主要挑战是如何确保设计的按时签发。由于信号完整性工程师通常只能在设计周期的后期发现问题并提出更改要求，设计师们于是不得不一遍又一遍地重复设计 - >布线 - >重新布线这一循环。当SI专家发现与基本反射相关的SI问题如不正确的布线拓扑结构、丢失的终止信号、过冲、回铃或延长的延迟建立时，设计师们的工作则必须重头再来。这一切都令人感到沮丧，特别是当SI专家知道这些基本问题其实可以更早地得到解决。在设计后期发现问题，意味着设计团队之前投入的布线精力都白费了，他们...

2018 Annual HLS Survey Results

By dpursley | 13 Dec 2018

Earlier this year, we performed the annual high-level synthesis (HLS) industry survey to get an idea of the industry’s expectations of HLS. As in last year’s survey , approximately half of the responses were from current HLS users, and half were from non-users. This year’s anonymous survey focused on...

Automotive Summit: The Road to an Autonomous Future

By Paul McLellan | 13 Dec 2018

Before Thanksgiving, Cadence held an Automotive Summit. I was going to dive into some of the detailed material presented, but it occurred to me that it might be a good time to step back and take a look at where we are in the industry as a whole. I&#3...
