"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
