Ensuring Data Integrity And Performance Of High-Speed Data Transmission


In key electronics applications such as data centers, automotive, and 5G, the data speed and volume are increasing at an exponential rate. Data centers require data transmission (Figure 1) as high as 112Gbps, which can be achieved only using PAM4 signaling. The automotive industry is dealing with the challenges of transferring data between various electronic control units (ECUs) at a very high ... » read more

Minimizing EM/IR Impacts On IC Design Reliability And Performance


By Joel Mercier and Karen Chow As technologies and foundry process nodes continue to advance, it gets more difficult to design and verify integrated circuits (ICs). The challenges become even more apparent in 5nm and below nodes, and as the industry moves away from fin field-effect transistor (finFET) and into gate-all-around field-effect transistor (GAAFET) technologies. There are many prob... » read more

Overcoming The Growing Challenge Of Dynamic IR-Drop


IR-drop has always been somewhat of an issue in chip design; voltage decreases as current travels along any path with any resistance. Ohm’s Law is likely the first thing that every electrical engineer learns. But the challenges related to IR-drop (sometimes called voltage drop) have increased considerably in recent years, especially the dynamic IR-drop in the power/ground grid as circuits swi... » read more

Bringing Scalable Power Integrity Analysis To Analog IC Designs


Power integrity is a broad term in integrated circuit (IC) design and verification. However, when IC engineers are working through design signoff, power integrity analysis focuses on three specific aspects of a design: Power: Verify the chip design as implemented provides the total predicted power under different operating modes. Performance: Find and eliminate performance issues affect... » read more

Pushing Memory Harder


In an optimized system, no component is waiting for another component while there is useful work to be done. Unfortunately, this is not the case with the processor/memory interface. Put simply, memory cannot keep up. Accessing memory is slow, and it can consume a significant fraction of the power budget. And the general consensus is this problem is not going away anytime soon, despite effort... » read more
