Saber's most powerful digital analog mixed signal simulation software

SABER The most powerful digital analog mixed signal simulation software

In terms of use , SaberDesigner The application field of Pspice To be broader ,SaberDesigner It can not only be used in circuit simulation , It can also be used for electromechanical 、 Electromechanical fluid 、 Simulation of hybrid systems such as optical electromechanical , and PSPICE Due to the limitation of Library and simulator , So it can only be used in circuits （ Analog and digital ） The simulation of , The two are not software of the same order of magnitude in nature .

One 、SaberDeigner The performance of the simulator is better than PSPICE The simulator of is high
SaberDesigner Adopted 5 Different algorithms are proposed to meet the different requirements of different circuit systems for simulation convergence , In addition, the adaptive variable step size algorithm is used in time domain simulation to improve the simulation efficiency , In solving nonlinear large signal system （ Such as ： Switching Mode Power Supply ） The piecewise linear method is adopted , It solves the problem of non convergence when simulating large signal nonlinear systems .PSPICE The traditional method based on SPICE Algorithm , The convergence of simulation can only be modulated by setting the maximum superposition algebra, maximum step size and error accuracy , Its control means are relatively few . Due to the limitation of maximum step size , Therefore, the efficiency of time-domain simulation is not high , In nonlinear system simulation , Due to the lack of algorithm for piecewise linearization of system signals , It often causes non convergence of simulation . When dealing with the simulation of digital analog hybrid system ,SaberDesigner Adopts its patented Algorithm Calaveras Algorithm , It can achieve high efficiency in dealing with the synchronization of digital and analog signals ,PSPICE The traditional ping-pong algorithm is used to deal with the problem of digital analog synchronization , Its efficiency is relatively low .

Two 、 Number and type of models ,Saber More advantages '
SaberDesigner Yes 1000 Multiple basic templates （ About... Are used for circuit simulation 200 individual ）,31000 Multiple devices （ Among them, the devices used for circuit simulation are about 21000 individual ）, and PSPICE There are about 150 individual , The devices are about 15000 individual . The types of devices of the two are similar , It covers the devices commonly used in circuit design .SaberDesigner Compatible with SPICE Standard model , Include SPICE2、SPICE3、SPICE4、PSPICE、HSPICE. and PSPICE Only compatible with SPICE2/3/4 Model .

3、 ... and 、 Modeling methods
From the perspective of modeling method ,PSPICE Only by parameter extraction 、 Modify the existing device model parameters 、 And the method of macro model construction , It is impossible to model the behavior of devices through modeling language , and SaberDesigner In addition to the above methods , You can also use its patents MAST Language establishes the behavior model of devices , To simplify the device model , The purpose of improving simulation efficiency . in general , There is little difference in the type and quantity of models used in circuit simulation , But in terms of model compatibility and modeling ability ,SaberDesigner Better .

Four 、 Front and rear end processing capacity
SaberDesigner There is a special schematic diagram input tool SaberSketch, It also supports mentor、cadence Schematic diagram input tool for schematic diagram input .SaberDesigner There is also a patented tool WaveForm Calculator, Contains 70 Various operation functions , It is specially used to calculate waveforms and various measurement result data . This tool enables designers to be more flexible 、 Convenient analysis of various graphic data , Very useful for engineering design . in addition , From the operation of graphic files （ Zoom in 、 Reduced waveform ）,SaberScope（ Support mouse drag and drop ） Than Pspice A/D It's a lot easier .

5、 ... and 、 Analysis setting and operation
From the perspective of analysis settings SaberDesigner There are many settable variables provided , Therefore, its setting is also more complex , and PSPICE Less settable variables , Therefore, the setting is relatively simple ; but SaberDesigner Because there are many variables provided , It also gives users more freedom to control the simulation process , After mastering the meaning of each setting , Can be faster 、 More efficient 、 More accurate simulation .PSPICE Because there are few settable variables , So there are problems （ Such as convergence problem ） when , There are few ways to solve the problem .PSPICE Only DC sensitivity analysis can be carried out in , and Saber Then DC 、 transient 、 Analysis of AC Sensitivity , Be more comprehensive .

6、 ... and 、 External interface
From cooperating with other software （ Collaborative simulation ） In terms of ability ,PSPICE There are few external interfaces , and SaberDesigner With strong cooperation ability ： Have digital simulation software interface MdlSim, Can be compared with digital simulation software Modelsim Conduct collaborative simulation . Have system simulation software interface SaberLink for MATLAB, It can work with system simulation software MATLAB Exchange simulation data , simulation model , Can also be combined with MATLAB Simulink Collaborative simulation . Have special tools SaberRT, It can be done with DSPACE、ADI Combined with online hardware in the loop simulation .
