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 servers.
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.
