In DDR4, DFE is utilized to address signal integrity issues of the data …
WebMar 30, 2024 · An IBIS (.ibs) file is a human readable, text-editable file, and it contains multiple sets of measured or simulated table-based data representing how the device behaves. In the case of an output model, the data would contain several lists of supply voltage vs. output current (I-V) data for pullup/pulldown and power/GND clamp. WebJun 27, 2024 · However, statistical analysis can only implement linear time invariant (LTI) algorithms, such as CTLE, but not non-LTI blocks, such as DFE. To overcome this drawback, Altera IBIS-AMI models implement an approximated DFE model, which is modeled as an LTI block, in statistical analysis. This improves simulation accuracy, …
WebApr 14, 2015 · This brief presents an adaptive continuous-time linear equalizer (CTLE) and one-tap decision feedback equalizer (DFE) using the spectrum balancing (SB) method. The SB method is extended for not only CTLE but also DFE with the aid of gain characteristics of one-tap DFE. Thus, adaptation loops for each equalizer type are merged to a single … WebIn DFE modes where data rate > 10312.5 Mbps, the device performs the same optimization as in CDR mode with the addition on performing full DFE calibration of the DFE coefficients. When calibration is completed the best DC offset, RX CTLE, and DFE coefficient settings are applied to the receiver.
