Qucs-S (Qucs with SPICE) is a powerful, open-source circuit simulator fork that bridges the gap between the user-friendly graphical interface and industry-standard SPICE simulation kernels. Unlike the original Qucs, which uses the internal qucsator engine, Qucs-S allows you to harness backends like Ngspice , Xyce , and SpiceOpus for professional-grade analog, digital, and RF analysis.
