XE-CCNASC (Capacitive Coupling Noise Analysis Simulation Cut) generates a Spice-simulatable netlist along with control file that includes the complete context of a victim and aggressors for Spice simulation.  XE-CCNASC inputs a hierarchical shcematic spice netlist and/or exracted dspf netlist, automatically derives circuit properties and logical equations for each net and transistor in the netlist, and stores these data in XE-Core engine. XE-CCNASC then generates spice deck based on victim node and aggressor nodes identified by corresponding coupling capcitance from the victim node. Unique simulation control files will be generated for 4 different types of CCNs: high-up, low-up, high-down, low-down.

A circuit can be a victim or aggressors, and following is an example of a victim and an aggressor in a cut which describes how CcnaSc generats a circuit from original input schematic netlist.

A Circuit can be a Victim or Aggressors:  Victim: Driver and feedback loop.   Aggressors: Driver only. Red: driver devices Blue: Victim feedback-loop devices Black: Load devices Green: Control Path devices Cyan: Not in cut devices. Modeling of Load devices for vimctim and aggressor: For Victim: Complete-CCR Load model For Aggressor: Miller effect load model

 Following circuit with label shows example of sensitizing a state node (LU Noise).

Sensitization Types Types are defined with respect to CCR output nodes.  Strong/Weak: Weff driving Z-node and capacitance exposed to Z-node High/Low/Rise/Fall/Enable: Voltage levels and waveforms. For Victim: .IC low on the state node High weakly on the other side Enable feedback-loop Turn Off driving control devices Turn On feedback control devices For Aggressors: Rise strongly on the state node Disable feedback-loop Turn on driving control devices
