If you're staring out at the world of semiconductor memory IP and
wondering how to make heads or tails of it, you've got sympathetic company. And
yes, for electronics systems design engineers, it does seem like controlled chaos out there.
But Cadence offered a little clarity this week
with a live, online panel moderated by Tom Hackett, Cadence Product Marketing Director and an expert on verification IP who has written extensively about these challenges. On the panel were:
The chat quickly grappled with one of the major issues of the day: rapidly changing memory protocols. Take LPDDR, which is now up to LPDDR4 in its evolution.
Elsasser walked the audience through the differences in each generation, ending with design challenges involving the two most recent, LPDDR3 and 4:
"The increasing speeds of LPDDR3 and LPDDR4 generate new design challenges. Power management in the SoC is critical to minimize system power. The SoC must manage tradeoffs between power and high-frequency operation."
The panel also tackled Wide I/O, Hybrid Memory Cube (see image, right), and DDR 4 as well as verification challenges and opportunities for each.
I won't spoil the fun. Please check out the complete chat and let us know what topics you'd like us to schedule chat sessions for in the future.
