Overcome High Speed Digital Design Challenges: Part 1 - Is Simulation a Requirement for Memory Designs?
The Double-Data-Rate DDR memory channel is found
in a wide range of applications: smartphones, tablets, notebooks, desktops, and
The famous DDR3 can reach 2.133GBps per cupper lane at 1.5V
SSTL15 technology, while DDR4 starting at 2.4GBps per lane with 1.2V POD12
technology trying to hit 3.2GBps. How can a designer find out the key enablers
to make DDR3 and DDR4 channels work successfully? Can we depend on trial and
error to meet the target?
In this webcast, we are proposing simulations
hardened by measurements to detect the key enablers of the DDR3 and DDR4 memory
channel. We will show an example of DDR3 memory channel running at 2.133GBps and
how DDR4 technology can help us reach 2.4GBps.
