Synopsys DDR memory IP supports Six DDR
Standards in single PHY
Synopsys, provider of both IP and VLSI design software
has made its new IP core DesignWare DDR multiPHY to support
six DDR SDRAM standards, which include LPDDR2, LPDDR/Mobile
DDR, DDR3, DDR3L (1.35 V), DDR3U (1.2x V), and DDR2. This
IP allows VLSI designers to have their chip access any of
these six DDR standards from single PHY for broad range
of applications. The DesignWare DDR multiPHY supports data
rates from 0 to 1066 Mbps and offers a DFI 2.1 compliant
interface to the memory controller.
"Memory interfaces continue to be one of the key IP
requirements we see in chip development. New standards such
as DDR3, DDR3L and LPDDR2 are designed to meet system performance
requirements while utilizing less power," said Dr.
Keh-Ching Huang, Head of Marketing and IP Solution Planning
at Global Unichip. "By supporting all facets of the
DDR standards, Synopsys' unique DesignWare DDR multiPHY
enables us to quickly incorporate the necessary functionalities
into our SoC designs with less risk."
The DesignWare DDR multiPHY features include Delay Lock
Loop (DLL) bypass modes for operation below 200 MHz, I/O
retention mode to allow the chip's power supplies to be
shut down completely while a small number of I/Os remain
powered on to keep the external SDRAMs in self refresh mode.
This IP is ready to support the anticipated DDR3U standard
operating at 1.2 or 1.25 V. Additionally, the DesignWare
DDR multiPHY provides built-in data training circuits to
enable in-system calibration, providing optimized system-level
timing without material interaction with the memory controller.
"It has become as important to minimize power as it
has to minimize overall chip cost in portable electronics,"
said John Koeter, vice president of marketing for the Solutions
Group at Synopsys. "The DesignWare DDR multiPHY not
only offers designers the flexibility to utilize any DDR
SDRAM in the system through simple software control, it
also features a power-conscious design that minimizes the
silicon area and cost."
