Hello,
im wor?ing on a project about simulation with Pspice and LTspice. in a part of my project i need to write about differences between this two softwares.
As we know LTspice is free but we schuld buy Pspice too expensive. i want to know what is the advantage of Pspice compare to other one that companies spend a lot of money to buy it while they can use LTspice for free.
Thanks
Ali
Simulating using abstract models is the most practical way to realize a circuit, LTpsice and other simulation packages (TINA, Top SPICE ect.. they all good for the job) users may be more critical on the UI aspects, example Ltspice has a poor UI, but hey its FREE!, Pspice has some really useful and interesting tools that sits on top of the simulator like the PSpice Optimizer, and Graphing Math Functions and many more interesting stuff to get the job done. However most people (non-engineering thinking) don't use this level of design to realize a circuit. They only looking for equivalent aspects trying to get as close to reality as possible. which is actually useless, as there are way to many dynamics at play typical (Simulation vs Real World debate)
As a side note I own some pretty impressive books, I would say some of the best Circuit Simulation literature that exist is written for Pspice
PSpice for Analog Communications Engineering
PSpice for Circuit Theory and Electronic Devices
PSpice for Digital Communications Engineering
PSpice for Digital Signal Processing
PSpice for Filters and Transmission Lines
These are just some of the good stuff written for Pspice, there are lots more.
