Samsung authors report a configurable channel model for DDR4-3DS PHY verification

Samsung Semiconductor India authors report an in-house parameterized channel model integrated into a DDR-PHY verification environment for DDR4-3DS memory. The model injects routing and board delays, skew, crosstalk distortion, duty-cycle variation, setup and hold stress, and glitches; the paper says it enabled RTL-level training-algorithm checks and led to RTL and specification updates in reported cases.
