We believe in “Firsts”
• It’s in our DNA.
• Bill Hewlett and Dave Packard shaped our
purpose of believing in firsts 75 years ago.
• It launched Silicon Valley.
• We are committed to bring you a new
generation of firsts – unlocking insights for
you so you can bring a new generation of
technologies into the world.

ADS DDR4 Simulation to Compliance Test User Story
1. As a DDR controller designer at an IC company, I need to swap out the simulated testbench’s generic controller model with my controller I/O model…
2. As a PCB/package/DIMM designer at an OEM or IC company, I need to swap out parts of the simulated testbench’s generic channel cascade with the post-layout EM-based model of my package (or PCB or DIMM)…
3. As a DRAM I/O designer at an IC company, I need to swap out the simulated testbench’s generic DRAM model with my DRAM I/O model….
(for all three)…then I want to run a sign-off compliance test on the simulated test bench waveforms before committing to fabrication. I want to run the exact same tests on the simulated testbench that I will run on my ‘scope in the test lab when get my prototypes back from fab.

Summary
• ADS simulates the physical channel effects of I/O drivers/receivers
and package/PCB/connectors between MCH and DDR4 memory
• Simulated waveforms are used to run DDR4 compliance test
• Compliance sign-off report is generated from the simulated waveforms
before committing to fabrication. Exact same tests can be run in the
test lab when hardware prototypes come back from fabrication
