These VIP offerings join the extensive Cadence VIP library, which provides a comprehensive portfolio for automotive applications including LPDDR 4/5, Ethernet TSN, MIPI CSI-2, DSI-2 and I3C, DisplayPort, CAN and eMMC.
He cited several trends driving this need--new smaller nodes can increase the number of missed transistors during traditional testing, high-speed bus interfaces (such as LPDDR, PCI Express, and USB 3.0) require faster read/write turnaround times than can be achieved with traditional ATE, and new packaging techniques such as heterogeneous packaging are driving higher escape costs as multiple known good die are integrated into a single 2.5D/3D package.
"The MacBook Pro uses 16GB of very fast LPDDR memory, up to 2133MHz.
The Memory Controller also offers a DFI 2.1-compliant interface to the DDR PHY, delivers memory system performance of up to 2133 Mbps and supports the DDR3, DDR2, LPDDR and LPDDR2 SDRAM standards.
Under this agreement Rambus has granted NVIDIA a patent licence for certain memory controllers at a 1% royalty rate for SDR memory controllers and a 2% royalty rate for other memory controllers, including DDR, DDR2, DDR3, LPDDR, LPDDR2, GDDR2, GDDR3, GDDR4 and portions of GDDR5 memory controllers.
The DesignWare DDR5 and LPDDR5 IP solutions support all required features of the DDR and LPDDR specifications, enabling designers to incorporate the necessary functionality into their SoCs:
At DesignCon, the company exhibited technologies that extend from EDA tools and physical-layer test software to BERTs, logic analyzers, oscilloscopes, and protocol analyzers and exercisers--with emphasis on the USB Type-C ecosystem, signal and power integrity, PAM-4 and 100G/400G data-center standards, and test and validation of the latest generation of PCIe and DDR/ LPDDR standards.
The mobile devices (LPDDR, LPDDR2, LPDDR3) are optimized for low power applications.
With access to the next-generation protocol and having additional flexibility between DDR and LPDDR, Cadence is allowing us to further innovate and provide greater differentiation and value to our customers.
Loberg at Tektronix listed several test offerings released over the past year, including a comprehensive test solution for LPDDR. He added, "Tektronix offers integrated PHY-layer testing and debug of the LPDDR4 standard in its DDR-LP4 analysis software.
