It's harder to drive, but the convergence is just as good/bad as the user sitting in front of it. Sonek, Applications of PSPICE Simulation. This was done in Figure 14 where we used the VPULSE and IPULSE sources from. implemented by idc and ipulse, respectively under the library of analoglib. Open the Model Editor from Start/All Programs/Cadence. Use of PSpice with OrCAD Capture 2.1 Step 1: Creating the circuit in Capture. We’ll approach the modeling of this core with the first method. impulse Workbench Extension SPICE (Simulation Program with Integrated Circuit Emphasis) characterizes a group of electronic circuit simulator software packages. A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. PSpice supports two models of magnetic core, the Jiles-Atherton and the Spice Plus model. Anyway, not to continue into the relative differences of the various packages, I'll simply close in saying: no, there's nothing fundamentally different about Altium's. The PSpice model of a core can be obtained from the B-H curve of ferrite from the Datasheet and from the geometrical data of the core. VPULSE, IPULSE: voltage or current pulse. In short, it doesn't matter what you're paying (or not), they all suck uniformly, just in different ways. gram is perhaps the hardest part of circuit simulation using PSpice. PSpice is a PC version of SPICE (which is currently available from OrCAD Corp. They almost all have custom tweaks, like PSpice's proprietary notation (syntax, built-in functions, and probably convergence tweaks), Altium's partial support of many things (including some PSpice, and maybe just a hint of HSpice), and probably most significantly, LTSpice's heavily tweaked solver ("modified TRAP", actual real no fooling multiprocessor support, etc.). It was for this reason that SPICE was originally developed at the Electronics Research Laboratory of the University of California, Berkeley (1975), as its name implies: S imulation P rogram for I ntegrated C ircuits E mphasis. VSFFM VSIN IEXP IPULSE IPWL IPWLFREFOREVER IPWLFNTIMES IPWLREFOREVER. VPULSE, IPULSE: pulse waveform, used to create square waveforms. PSpice® Users Guide includes PSpice A/D, PSpice A/D Basics, and PSpice. All of them, from free 3f5 SPICE, to $10k+ Altium's SPICE engine, are all based on either the original Berkeley 3f5, or the somewhat later XSPICE (also an academic byproduct Georgia Tech I think?). This tutorial is designed to show you how to use the PSpice circuit simulation form. IPULSE 3 0 PULSE (0 1 mA 5ns 1ns 1ns 100ns 200ns). For physical systems, this means that we are looking at discontinuous or impulsive inputs to the system.I've found it's exactly as easy and troublesome as any other commercial grade simulator. In PSPICE, four different models are implemented: level 1 through level 4. In this session we study differential equations with step or delta functions as input. Below the list of Jiles-Atherton model parameters: Open the Model Editor from Start/All Programs/Cadence/Release xy. 3) Go to File > New > Project 4) Enter a name (i.e. 2) Choose OrCAD Designer PSCPICE as your Cadence Product Choice. We’ll approach the modeling of this core with the first method. 1) To Open PSPICE, go to folder ORCAD 16.0 and choose the program OrCAD Capture CIS a) Vista Users should run Capture as Administrator (under the right click menu). Arrow_back browse course material library_books PSpice supports two models of magnetic core, the Jiles-Atherton and the Spice Plus model.
