The Role Of NoCs In System-Level Services


The primary objective of any network-on-chip (NoC) interconnect is to move data around a chip as efficiently as possible with as little impact as possible on design closure while meeting or exceeding key design metrics (PPA, etc.). These networks have become the central nervous system of SoCs and are starting to play a larger role in system-level services like quality of service (QoS), debug, p... » read more

Better Analytics Needed For Assembly


Package equipment sensors, newer inspection techniques, and analytics enable quality and yield improvement, but all of those will require a bigger investment on the part of assembly houses. That's easier said than done. Assembly operations long have operated on thin profit margins because their tasks were considered easy to manage. Much has changed over the past several years, however. The r... » read more

Interconnect Challenges Grow, Tools Lag


Interconnects are becoming much problematic as devices shrink and the amount of data being moved around a system continues to rise. This limitation has shown up several times in the past, and it's happening again today. But when the interconnect becomes an issue, it cannot be solved in the same way issues are solved for other aspects of a chip. Typically it results in disruption in how the t... » read more

eFPGA As Fast And Dense As FPGA, On Any Process Node


A challenge for eFPGA when we started Flex Logix is that there are many customers and applications, and they all seemed to want eFPGA on different foundries, different nodes and different array sizes. And everyone wanted the eFPGA to be as fast and as dense as FPGA leaders’ on the same node. Oh, and customers seem to wait to the last minute then need the eFPGA ASAP. Xilinx and Altera (Intel ... » read more

The Need For 3D IC Packaging And Design Evolution


If you are familiar with Moore’s Law, you’ve probably read pronouncements that the premise of transistor counts doubling each year is reaching a wall due to complex process technologies and device physics limitations. Regardless of how well transistor counts continue to scale, market segments continue to drive the thirst for more compute performance and fast time to markets. Artificial i... » read more

Which Chip Interconnect Protocol Is Better?


Semiconductor Engineering sat down to the discuss the pros and cons of the Compute Express Link (CXL) and the Cache Coherent Interconnect for Accelerators (CCIX) with Kurt Shuler, vice president of marketing at Arteris IP; Richard Solomon, technical marketing manager for PCI Express controller IP at Synopsys; and Jitendra Mohan, CEO of Astera Labs. What follows are excerpts of that conversation... » read more

AI, Performance, Power, Safety Shine Spotlight On Last-Level Cache


Memory limitations to performance, always important in modern systems, have become an especially significant concern in automotive safety-critical applications making use of AI methods. On one hand, detecting and reporting a potential collision or other safety problem has to be very fast. Any corrective action is constrained by physics and has to be taken well in advance to avoid the problem. ... » read more

Software In Inference Accelerators


Geoff Tate, CEO of Flex Logix, talks about the importance of hardware-software co-design for inference accelerators, how that affects performance and power, and what new approaches chipmakers are taking to bring AI chips to market. » read more

Analog Simulation At 7/5/3nm


Hany Elhak, group director of product management at Cadence, talks with Semiconductor Engineering about analog circuit simulation at advanced nodes, why process variation is an increasing problem, the impact of parasitics and finFET stacking, and what happens when gate-all-around FETs are added into the chip. » read more

Verdi Transaction Debug Solution: Unified Performance Analysis And Debug For Interconnect


In modern systems on chip (SoCs), where Arm AMBA protocols are intensively used as standard intellectual property (IP) interfaces, the interconnect is usually required to bridge and facilitate the communication between many different IP interfaces. The interconnect presents one of the biggest challenges of SoC verification, considering the different kinds of protocol interfaces, conversion of d... » read more
