A Waveform-Based TX Modeling Approach for Silicon Level Accurate C-PHY Analysis
白皮书
The MIPI C-PHY signal has three levels, which makes it difficult to implement an accurate model using existing IBIS files. In particular, to correctly represent the chip’s transition shape, it is necessary to have rise and fall time information for each of the three C-PHY levels, rather than a single rise/fall time value. Moreover, accurate state-level representation requires pull-up and pull-down information for each level. To bring this level of accuracy into silicon-level simulation, Keysight ADS introduces a new C-PHY Waveform Source.
