With HyperLynx vers. 2.5, I have run "General Batch Simulation" between processor and LPDDR4.
One specific result came up which I could not understand nor explain. The simulation-result showed our design had "Fail" on one of the DataMask-signal on the "Fast Corner" regarding "Multi Cross Threshold"-column. However, when changing the driver strength one step, the result went from "Fail" to "Pass".
Does not "Multi Cross Threshold" have a connection to the voltage-level regarding ViH, while changing driver strenght have a connection to the rising edge?
Could you explain the connection between "Multi Cross Threshold" and driver strenght?
Thank you in advance.
