From calling drawing program to simulation, it can be completed in one environment, and there is no need to switch working environments everywhere.
2 Complete graphic viewing function:
Saber provides SaberScope and DesignProbe to view the simulation results, and SaberScope is more powerful.
3 Various complete advanced simulations:
Offset point analysis, DC analysis, AC analysis, transient analysis, temperature analysis, parameter analysis, Fourier analysis, Monte Carlo analysis, noise analysis, stress analysis, distortion analysis, etc.
4 modularity and hierarchy:
Some circuit blocks can be created as symbolic representations of hierarchical design, and sub-circuits and the whole circuit can be simulated.
5 simulation behavior model:
The possible situations in the practical application of the circuit, such as temperature change and parameter drift of each component, are simulated.
6 strong convergence analysis:
Saber chooses the algorithm very carefully to minimize the possibility of encountering convergence problems, which other simulators often encounter and cannot solve. Saber used five powerful algorithms in turn to solve the convergence problem. In the system evaluation, Saber proposed piecewise linear evaluation of accurate system equations. In this way, even difficult simulation problems, such as transient analysis of sharp signals, can be well controlled.
7 simulation accuracy:
When conducting simulation, you need to ensure that the simulation results can accurately reflect the operation of your physical system. According to Avant! With rich design and simulation experience, Saber's default precision control can provide high-precision simulation results within acceptable simulation time.
8 model and simulator separation:
Saber simulator is completely separated from the simulation model, which allows you to completely access and control the model. You can view the contents of the template, modify it, and make another template. Create your own model and add it to the library, or create your own library. You can use Avant! MAST, or C, C++ and FORTRAN can all be used to write models or subcircuits. In addition, avantgarde! It provides various types of libraries, including tens of thousands of library models, high-precision Si models of industrial standard Star-Hspice simulator, IGBT models used in high-voltage equipment, S-domain and Z-domain models used in communication systems and so on.
9 support general CAE system:
Saber's various operations in SaberDesigner graphic environment can be well integrated with Cadence system, Mentor graphic system and Innoveda system. In this way, you can easily call all the functions of Saber simulator in other familiar environments.
10 supports full-line analysis function:
Because Saber is a mixed signal simulator based on HDL, it can do statistical analysis, which is difficult or impossible for other tools. When combined with HDL-based models, Saber and Inspecs allow statistical analysis of any model parameters. A simple example is an operational amplifier input bias voltage circuit. Parameters can be easily changed in Saber MAST HDL model, but it is almost impossible to change in SPICE macro model. Another example is the ability to change digital circuit parameters, such as delay in Monte Carlo analysis.
Of course, Saber supports all standard simulation analysis, including DC operating point analysis, transient analysis, AC noise analysis, distortion analysis and Fourier analysis. More specifically, Saber and Inspecs can support Monte Carlo analysis, stress analysis, sensitivity analysis and parameter scanning analysis. All analyses can be used in any hybrid system.
Output result view of 1 1
Generating simulation data is only one aspect of successful system analysis. In the Saber design environment, you can use the powerful and easy-to-use SaberScope graphic waveform analyzer to view and analyze the results. Saber can create a default result file, or you can define your own simulation data to be extracted. Then, you can use SaberScope to view signals and parameters in the system or model hierarchy, or just the main waveforms. If you need to see new signals, you can directly extract their data without re-simulation. This unique function of Saber can save your precious time and extract important data very easily.
12 saber collaborative simulation;
Saber's joint simulator combines the advantages of Saber's mixed signal and mixed technology with ModelSim, ModelSim/PLUS model technology or Verilog-XL of Cadence. This interface is avant-garde! Saber simulator has the advantage of co-simulation with industry standard VHDL and Verilog simulators used in other major design environments. These design environments include Avant! SaberSketch, Mentor Graphics, Cadence and Innoveda, etc. The results of analog output are arranged in time in SaberScope waveform analyzer, which is convenient for you to observe the analog results of related analog and digital signals.
Advantages of Saber collaborative simulation
Collaborative simulation combines mixed-signal design with the current main design environment.
Use the patented Calaveras algorithm to get the best performance.
You can watch analog and digital results in chronological order on the same screen.
Use real top-down design theory.
Easy to reuse design.
Advantages of 13 collaborative simulation;
Nowadays, many designs put the analog/mixed signal part and the digital part on the same chip. Wan! Saber is a real single-core mixed-signal simulator. It can be used to develop high-specification systems or IC. However, most digital circuits IP are implemented by Verilog or VHDL. By combining Saber's mixed signal simulator with industrial standard digital circuit simulator, Saber collaborative simulation can easily analyze the behavior of the system before physical realization. If Saber's latest Star-Hspice simulation library is used, Verilog, VHDL, MAST and Star-Hspice simulation models can be mixed in the same simulation. What was the result? Reduce duplication and bring products to market faster.
14 Real top-down design:
Saber realizes its real top-down concept by providing designers with analog and digital hardware description languages. The model of analog and mixed-signal devices adopts MAST language, namely Avant! Mixed-signal HDL language is used to describe large digital devices, while VHDL or Verilog is used to describe them. This compatibility allows you to model and simulate behavioral devices, functional devices and physical devices in analog and digital fields.
This design method allows you to simulate at every design level from top to bottom, which is helpful to solve problems. Once some functional modules are verified, they can be saved for other designs, which is of great significance to the time to market.
Fast simulation of 15 based on Calaveras algorithm;
Saber collaborative simulation technology adopts the analog/digital algorithm patented by Calaveras, which allows the digital simulator (Verilog-XL, ModelSim) and Saber to use the best time step for simulation. It makes the data exchange between digital simulator and analog simulator only when necessary, which can greatly improve the simulation speed. Other corresponding simulation theories need to exchange information at each time step and reevaluate previous calculations through backtracking. All these greatly affect the simulation speed, especially when calling multipole feedback loop.
16 analog/digital boundary interface:
Saber hybrid simulation products are avant-garde in the application of analog/digital boundaries! The special supermodel interface model makes the digital part of the design have correct circuit characteristics at the digital-analog interface. Hypermodel is automatically added to the design when the model is generated, which makes the digital pins connected with analog devices have accurate analog circuit simulation characteristics. Saber provides you with at least 3500 supermodels of standard logic pins in different processes such as TTL, CMOS and ECL. These supermodels can be modified to match user-defined digital features.
Supermodels are all done in MAST language (instead of writing digital-analog interfaces in the design like competitors). This means that you can create your own supermodel library if there is no suitable model in the library.
