"ACVS-IBIS  : The fast transient simulation for (LP)DDR" is specialized solution for  DDR/LPDDR memory bus channel analysis, and it provides the functions of fast & automatic channel configuration, analysis, measure parameters and generating the customized engineering report.


1) Introduction


"ACVS-IBIS : The fast transient simulation for (LP)DDR" is the specialized solution for DDR/LPDDR memory bus channel optimized transient analysis and customized report generation. Unlike conventional simulators, it contains various new technologies - SimX engine including causal impulse response transfer method, machine learning based automatic channel configuration, Hawk-Eye mode for worst bit simulation to increase accuracy and efficiency.  The goal of ACVS-IBIS solution is to provide accurate analysis results while overcoming the limitations of complex settings and long analysis times in channel transient analysis.


2) Key Features


 a. Unique Accuracy


- SimX engine 


 . Accurate S-parameter to impulse response transfer method

  : Adopt the new casual impulse response transfer method to estimate the channel characteristics accurately  by expanding S-parameter adaptively to the unknown upper and lower frequency band(Patented)

 . Adopt the specialized full transient non-linear solver for high speed channel analysis


b. Unique Efficiency


 - supports the 3 type of input waveform mode


 . PRBS mode 

  : generalized LFSR PRBS input mode 


. Hawk-Eye mode

  : faster analysis than PRBS mode and generate the pseudo worst eye-diagram output

  : verify the channel characteristics and pseudo worst bit pattern calculation 

  : 3-options of Fast/Optimal/Strict


. Manual bits mode 

  : User defined bits input mode (supports the bit file export/import function)


- Channel s-parameters's termination and auto connections between s-para. models and auto Tx/Rx IBIS model connection. 

  . provide the efficient channel configuration method for the multi-port DDR/LPDDR models.


 - Multiple analysis case setups and simultaneous analysis support

 . After setting of analysis cases for the various Data rate, IBIS model/corner, Read/Write mode it proceed the simulation simultaneously

   (Multi-cores support) and sequentially.


 c. Customized Report Automation


 - Support the new method for various parameters calculation and measure

 . Standard JEDEC and customized spec. of eye-diagram and mask violation

 . Eye-diagram chart viewer 

   : Marker, delta-marker, mask on/off, zoom in/out, capture functions
