Simulink allows you to simulate your system before you move on to hardware. You can explore and implement designs you wouldn't normally consider without having to code C, C++, or HDL code. You can explore a wide range of design options by modeling the system under testing and the physical plant. To simulate the behavior of all components of the system, your entire team can use a multi-domain environment. Your simulations can be packaged and shared with clients, suppliers, or collaborators. You can reduce the cost of prototypes by testing your system in conditions that are too risky or too time-consuming. Rapid prototyping and hardware-in-the loop testing can validate your design. You can trace your design from requirements to code. Instead of writing thousands upon lines of code manually, generate high-quality C or HDL code automatically. This code behaves in the same way that Simulink's model. You can then deploy it directly to your embedded processor or FPGA/ASIC.

Easy-wire mode allows you to connect elements with less clicks, and therefore less frustration. The unit-aware evaluation of expressions allows you to plot arbitrary signals, such as differential or power dissipation. You can design and analyze circuits faster with in-browser simulation. This allows you to test your circuit before you ever pick up a soldering tool. Advanced simulation capabilities include frequency domain (small signal simulation), stepping circuit parameters across a range, arbitrary Laplace function blocks, etc. With configurable plotting window, vertical and horizontal marker, and calculations for signals, you can work with multiple signals with ease. With just a few mouse clicks, you can create generic rectangular symbols to represent IC or system level wiring diagrams.

Ansys Exalto, a post-LVS RLCk extractor software solution, allows IC designers to capture unknown crosstalk between different blocks in their design hierarchy. It extracts lumped-element parasitics from the design hierarchy and generates an accurate model for electrical and magnetic coupling. Exalto interfaces well with most LVS tools, and can be used in conjunction with the RC extraction tool you choose. Ansys Exalto post LVS RLCk extraction allows IC designers to accurately predict electromagnetic and substrate-coupling effects for signoff on circuits previously "too large to analyze." The extracted models can be back-annotated to any schematic or netlist and support all circuit simulators. Modern silicon systems have seen a rise in RF and high speed circuits. This has made electromagnetic coupling a first-order effect that must be accurately modelled to ensure silicon success.

One animated circuit is equivalent to a thousand equations or diagrams. The schematic is accompanied by animations of voltages and currents. This gives a great insight into the operation of the circuit. The real-time simulation engine was custom-built to be fast and interactive. Simulate everything from simple logic gates and resistors to complex transistor-level designs and mixed-signal circuits with just one click. You can adjust potentiometers and LED current-limiting resistors while the simulation is running. Your changes will be reflected in real-time. The mini-waveforms that appear on top of the schematic wires are different for digital and analogue signals. Digital wires are color coded, while constant analog voltages are shown in numbers. In the XY mode, any pair of time domain signals can be plotted. The grid ticks and oscilloscope scale are automatically updated to convenient values when the data changes.

Pharos combines Ansys’ unparalleled EM engine power with a proprietary circuit simulation engine to perform coupling analysis. It also provides a ranking of potential EM-crosstalk aggressors per victim. Designers can identify the most vulnerable nets to help them make design decisions that will manage EM crosstalk and reduce risk. Pharos combines an unparalleled extraction engine power with a built in simulation engine to perform EM analysis. It also ranks potential EM crosstalk aggressors per victim network. This allows designers to concentrate on the most important nets in the design. It is difficult, if not impossible to identify all EM crosstalk vulnerable victim/aggressor net pair due to increasing design complexity and the wide range of magnetic field interference.

PathWave ADS provides integrated design guidance via templates to make it easier to get started. It is easy to find the part that you need with the extensive component libraries. Automatic sync allows you to visualize the physical layout and create schematic designs. Data allows teams to visualize whether their designs are meeting specifications. PathWave ADS's data display and analytics capabilities produce graphs, charts and diagrams that will give you design confidence. With wizards, templates, and design guides, you can quickly accelerate your design. The entire design flow includes schematic, layout and circuit. As frequency and speed increase on printed circuit boards (PCBs), signal and power integrity become more important. Electronic device failures can be caused by transmission line effects. To simulate the board accurately, it is necessary to model vias, traces, and interconnects.

It is based upon a complete representation for the qubit state, but avoids the explicit representation in terms of matrices of gates and other quantum operation.
