PrimeSim HSPICE is described as 'As IC geometries continue to shrink, the need for an accurate circuit simulator is critical. Designers require a highly accurate circuit simulator to precisely predict the timing, power consumption, functionality, and yield of their designs' and is an app. There are five alternatives to PrimeSim HSPICE for Mac, Windows and Linux. The best PrimeSim HSPICE alternative is Pspice, which is free. Other great apps like PrimeSim HSPICE are Ngspice, Gnucap, McCAD 3SPICE and MacSpice.
Software for Simulating Voltage and Currents of a text file net-list of a electronics components such as Resistors, Capacitors, inductors, transisters, Diodes, Voltage and Current Sources, etc.
Ngspice is a mixed-level/mixed-signal circuit simulator. Its code is based on three open source software packages: Spice3f5, Cider1b1 and Xspice. Ngspice is part of gEDA project, a full GPL'd suite of Electronic Design Automation tools.
McCAD 3-SPICE is based on the latest version (3F5) of Berkeley's SPICE 3 and permits interactive mixed mode circuit simulation. It was developed specifically to take advantage of the processing speeds available thus permitting extremely fast simulations.
Simulates and analyses electronic circuits that can range in complexity from a single resistor to an integrated circuit comprising tens-of-thousands of devices.
