HSPICEAutodesk EAGLE is recommended for hobbyists, engineers, and small to medium-sized teams involved in electronics design. It is particularly suitable for those who require powerful design tools with a balance between usability and advanced capabilities. While beginners can appreciate its intuitive interface, experienced designers will benefit from its sophisticated features and integration with other Autodesk software.
Altium Designer - PCB Design Software
Proteus - Proteus - Proteus is a great electrical suite for circuit simulation purposes. You can simulate a single processor or multiple ones at the same time. The application is a great alternative for Virtual System Modelling.
KiCad - A Cross Platform and Open Source Electronics Design Automation Suite
Pspice - OrCAD PSpice technology provides the best, high-performance circuit simulation to analyze and refine your circuits, components, and parameters before committing to layout and fabrication
EasyEDA - EasyEDA - Web-based EDA suite; runs in browser.
LTspice - LTspiceยฎ is a high performance SPICE simulation software, schematic capture and waveform viewer with enhancements and models for easing the simulation of analog circuits.
