Design and simulate your system in Simulink before moving to hardware. Explore and implement designs that you wouldn’t otherwise consider – without having to write C, C++, or HDL code. Explore a wide design space by modeling the system under test and the physical plant. Your entire team can use one multi-domain environment to simulate how all parts of the system behave. Package and share your simulations with collaborators, suppliers, and clients. Reduce expensive prototypes by testing your system under conditions that are otherwise too risky or time-consuming to consider. Validate your design with hardware-in-the-loop testing and rapid prototyping. Maintain traceability from requirements to design to code. Instead of writing thousands of lines of code by hand, automatically generate production-quality C and HDL code that behaves the same way as the model you created in Simulink. Then deploy it directly onto your embedded processor or FPGA/ASIC.

There are plenty of circuit simulators available on the market. Just read their ads: high performance, extremely fast, industry-standard (i.e. SPICE), easy to use, highly intuitive. If you want to see if a tool is worth using, try it yourself. That's what many NL5 users already did. I hope they will share their encouraging stories soon. A few words about what should you expect from NL5. It is not one more SPICE (and not even close), nor is it a SPICE replacement. For some tasks NL5 is far superior, for others simply good, and some tasks are not for NL5 at all.

Ansys Exalto is a post-LVS RLCk extraction software solution that enables IC designers to accurately capture unknown crosstalk among different blocks in the design hierarchy by extracting lumped-element parasitics and generating an accurate model for electrical, magnetic and substrate coupling. Exalto interfaces with most LVS tools and can complement the RC extraction tool of your choice. Ansys Exalto post-LVS RLCk extraction lets IC designers accurately predict electromagnetic and substrate coupling effects for signoff on circuits that were previously "too big to analyze.” The extracted models are back-annotated to the schematic or netlist, and support all circuit simulators. The proliferation of RF and high-speed circuits in modern silicon systems has raised electromagnetic coupling to a first order effect that must be accurately modeled to reliably achieve silicon success.

Electromagnetic (EM) simulation brings you insight before physical prototyping. Customize EM simulations for speed and accuracy. Integrate EM analysis with your circuit simulations. EM simulations can take hours to run. Shorten your import and export time by integrating your EM simulation software with PathWave Circuit Design software. Integrate EM analysis with circuit simulations to maximize efficiency. 3D EM solid modeling environment for creating arbitrary 3D objects and importing existing 3D models from other CAD environments. Prerequisite for preparing a 3D geometry for 3DEM simulation by defining ports, boundary conditions and material properties. 3D EM solid modeling environment and Finite Difference Time Domain (FDTD) simulator. Compliance testing for Specific Absorption Rate (SAR) and Hearing Aid Compatibility (HAC).

It gives you the flexibility to design and test electronic circuits, trying all the "what if" scenarios without ever worrying about faulty parts or bad connections. CircuitLogix supports analog, digital and mixed-signal circuits, and its proven SPICE simulation gives accurate real-world results you can trust. 3DLab is included with both versions of CircuitLogix and is a "virtual reality"-type of lab environment and is designed to closely replicate the appearance and functionality of actual devices and instruments. There are approximately 30 different devices and instruments available in 3DLab, including batteries, switches, meters, lamps, resistors, inductors, capacitors, fuses, oscilloscopes, logic analyzers and frequency counters.
