Ngspice
Ngspice is a highly optimized spice simulator that allows you to work with electronic and electric circuits. Circuits like these typically have transmission lines, JFETs, L/R/C diodes, and several other devices that are bound together by means of interconnection in a netlist. One of the flexibilities for the end-user is that they have the choice to input the combination having digital and analog as a mixed-signal circuit. The only drawback is that there is no support for schematic entry. The solution is fully compatible with multiple operating systems such as macOS, Windows, FreeBSD, Linux, and Cygwin.
