Week in Review: IoT, Security, Auto


Products/Services Rambus agreed to acquire Hillsboro, Ore.-based Northwest Logic, a purveyor of memory, PCIe, and MIPI digital controllers. The transaction is expected to close in the current quarter. Financial terms weren’t disclosed; Rambus said in a statement, “Although this transaction will not materially impact 2019 results due to the expected timing of close and acquisition accountin... » read more

Getting Ready for 32 GT/s PCIe 5.0 Designs


The transition from older PCI Express (PCIe) technologies to the latest Revision 5.0 is on an accelerated path, with system-on-chip (SoC) designers seeing a much faster roll out than they did with PCIe 4.0. The recent release of version 0.9 of the PCIe 5.0 Base Specification locks in the functional changes to the specification, allowing designers to confidently start their designs. With the rap... » read more

PCIe 4.0 Hangs In, PCIe 5.0 Coming On Strong


First introduced in 2003 as a universal serial chip-to-chip interface running at 2.5 Gbps, PCI Express (Peripheral Component Interconnect Express), also known as PCIe, has advanced several revisions with significant improvements to performance and other features with each new generation. Through broad support, backwards compatibility, and a consistent cadence of upgrades that doubled lane sp... » read more

PCIe In High-Performance FPGAs


In today's world, when the entire computing industry is talking about high-performance and high-speed applications using FPGAs, what are the factors that can assure such performance and speed? The value and success of today’s high performance computing applications in the areas of DNA Sequencing, High Frequency Trading (HFT) and Encryption/Decryption are predicated upon how fast data can be t... » read more

Software-Defined Test And Measurement


Software-defined radios, instrumentation and test are ramping up alongside a flood of new technologies related to assisted and autonomous vehicles, 5G, and military/aerospace electronics, breathing new life and significant change into the test and measurement market. Software-defined test adds flexibility in markets where the products and protocols are evolving or still being defined, and wh... » read more

Blog Review: April 4


Synopsys' Richard Solomon explains PCIe's upstream and downstream component naming and why understanding the perspective is key. Mentor's Cristian Filip dives into frequency domain analysis for high data rate SerDes links and the movement toward a simpler way of channel characterization. Cadence's Paul McLellan takes a look at the history of the RISC processors and the death of microcode ... » read more

32GT/s PCI Express Design Considerations


Today’s networking and rapidly emerging artificial intelligence (AI) applications are requiring more bandwidth in accelerators and GPUs, as well as faster interconnects to transmit and receive greater amounts of data. Towards the middle of 2017 the PCI-SIG industry consortium announced its latest specification, PCIe 5.0, which raised the data rate from 16GT/s to 32GT/s and doubled the link... » read more

Signal Integrity Methodology For Double-Digit Multi-Gigabit Interfaces


As data rates for serial link interfaces such as PCI Express (PCIe) Gen 4 move into the double digits, device modeling, interconnect modeling, and analysis methodologies must continue to evolve to address the shrinking design margins and increasingly challenging compliance criteria facing today’s engineers. To mitigate risk and optimize designs, it is critical to move analysis as far upstream... » read more

Memory Test Challenges, Opportunities


The semiconductor capital equipment market is on fire, and the memory chip test equipment sector is no different. But it is getting much more difficult on the memory side. Memory test vendors are contending with next-generation devices, such as 3D NAND flash memories, HBM2 chips, low-power double-data-rate DRAMs, graphics DRAMs, phase-change memories, magnetoresistive RAMs, and resistive RAM... » read more

Targeting And Tailoring eFPGAs


Robert Blake, president and CEO of Achronix, sat down with Semiconductor Engineering to discuss what's changing in the embedded FPGA world, why new levels of customization are so important, and difficulty levels for implementing embedded programmability. What follows are excerpts of that discussion. SE: There are numerous ways you can go about creating a chip these days, but many of the prot... » read more
