How to run accurate SPICE simulations without breaking the bank (or your laptop).

From Classroom to Real World: Why PSpice Student Version is Still the Best Free Tool for Circuit Simulation

You cannot simulate an entire ARM processor or a full switching power supply with 500 components. But for homework, class projects, and senior design sub-circuits (filters, amplifiers, oscillators), it is perfect. Pro Tips for Beginners (Avoid my mistakes) 1. Ground Everything PSpice is ruthless. If you forget to place a ground (0V reference) on your schematic, the simulation will throw a "Floating Node" error and refuse to run. Every circuit needs at least one ground.
