Develop and test your system using Simulink prior to implementing it on actual hardware. This allows you to explore and apply innovative designs that might typically be overlooked, all without the need to engage in C, C++, or HDL programming. By modeling both the system you are testing and the physical plant, you can investigate a broader design landscape. Your entire team can benefit from a unified multi-domain platform that simulates the interactions of all system components. You can also package and share your simulation results with team members, suppliers, and clients for collaborative feedback. This approach helps minimize costly prototypes by allowing you to experiment with scenarios that might otherwise be deemed too risky or impractical. Use hardware-in-the-loop testing and rapid prototyping to confirm your design's effectiveness. With this method, you can ensure traceability throughout the process, from requirements gathering to design and code development. Rather than manually crafting thousands of lines of code, you can automatically generate high-quality C and HDL code that mirrors your original Simulink model. Finally, deploy this code directly onto your embedded processor or FPGA/ASIC for seamless integration and operation. This comprehensive approach not only streamlines development but also enhances overall project efficiency.

Numerous circuit simulators exist in the marketplace today. Their advertisements boast about high performance, remarkable speed, being industry-standard (such as SPICE), and being user-friendly with a highly intuitive interface. To determine the effectiveness of a tool, it’s best to try it out for yourself, which is exactly what many users of NL5 have done. I look forward to hearing the positive feedback they will likely share soon. It’s important to note what to anticipate from NL5: it is not just another variation of SPICE, nor can it be considered a direct substitute. In certain applications, NL5 demonstrates significant advantages, while in others it performs adequately, and there are some areas where it may not be suitable at all. Ultimately, the versatility of NL5 makes it a compelling option for specific tasks within circuit simulation.

Electromagnetic (EM) simulation provides valuable insights prior to the physical prototyping stage. Tailor your EM simulations to enhance both speed and precision. Seamlessly integrate EM analysis with your circuit simulations to boost overall efficiency. While EM simulations can often require several hours to complete, you can significantly reduce both import and export times by linking your EM simulation software with PathWave Circuit Design software. This integration allows you to maximize your workflow by combining EM analysis with circuit simulations effectively. The 3D EM solid modeling environment enables the creation of custom 3D objects and supports the import of existing models from various CAD platforms. This is essential for preparing a 3D geometry for 3DEM simulation, which involves defining ports, boundary conditions, and material properties. Additionally, the environment includes a Finite Difference Time Domain (FDTD) simulator, which is vital for compliance testing regarding Specific Absorption Rate (SAR) and Hearing Aid Compatibility (HAC), ensuring that your designs meet necessary regulatory standards. By utilizing these advanced features, you can streamline your design process and enhance the effectiveness of your electromagnetic analysis.
