Learn how to interface with LTSpice using WAV files. Hw to use macspice to calculate current how to# LTSpice has the capability to record data from voltage and current nodes as part of a transient simulation. The data can be read back by voltage and current sources and used as inputs to other LTSpice circuits, viewed using a simple playback circuit or exchanged with common data analysis applications. In this article, examples of general purpose recording and playback circuits and details of the data format are explored.Īn intriguing capability of LTSpice is recording Transient simulation data as WAV files. I did not understand what this meant until looking at the detailed LTSpice specification and seeing how these specs aligned with low-level details of the WAV file format. One key thing to know is WAV files are not compressed. You put a number in, you get the same number out. Apparently, in the music industry, it is the ultimate for high-quality recording. Also, the data is organized into channels like you would expect in a music recording studio. However, the number of channels can be very large. I'm able to plot certain variables under test vs. Way beyond what music recording could require. How to plot voltage vs current in HSPICE/MacSPICE Ask Question Asked 6 years, 9 months ago Modified 6 years, 9 months ago Viewed 1k times 0 I have a transient simulation for a simple voltage divider for MacSPICE shown below. To me, this is a good format for a general-purpose, multi-channel data recorder.

Wow! Imagine an actual data recorder with over 60,000 channels, 32-bit analog-to-digital conversion, and over one billion samples per second. TRAN Analysis Models & Subcircuits MacSpice Tutorials Getting Started with MacSpice 1.1 Introduction SPICE is an analog-circuit simulator that is used to calculate and display the circuit behaviour. My tests found the maximum samples per second to be about ½ of the value in the table with a Transient simulation running for 10 nanosec. The current flowing through a component in a circuit is measured using an ammeter. Amperes is often abbreviated to amps or A. wave Circuit_Data.wav 16 10K V(ab) V(cd) V(ef) V(gh) Also, I could not verify the number of sampling bits beyond around 24 bits.Īll this is done by putting a. Measuring current Current is measured in amperes. I have deliberately not used the example from LTSpiceHelp. That example is appropriate for creating a WAV file that can be played back as audio. We are going in a totally different direction. 10K - The number of samples per simulated second.Think analog-to-digital converter resolution.

Now we need to calculate the total current in the reactive load:. There is also reactive current in phase 2 due to the 0.9 power factor but first, the real current from the 4.5kW load is 19.57A. All tend to fall apart when you go into areas of operation that the model maker didn't expect. 4.5kW + 2.5kW 230V 28.26A 4.5 k W + 2.5 k W 230 V 28.26 A. Many of the vacuum tube models found on the web are quite good, some aren't. The accuracy of any simulation depends on the quality of the models. This confuses many new users try plot i (vin). I don't know if it works on other emulators or virtualization programs.Īll three are often used by the tube heads here. 1 Spice 3 derivatives often convert names in netlists to all lowercase, but the command interpreter is usually case sensitive. It is made for Windoze and the Linear web site claims that it works with wine on Linux. It shows gain, distortion, harmonic stectra and just about anything that you can figure out how to ask it. The results of this analysis are used to calculate values for the the linearised, small-signal models of nonlinear devices. LTspice is a simulator and schematic drawing program that works with tubes, solid state devices and just about any circuit. It will not show signal loss of gain or amplification.

That's what the first two letters stand for. PSUD is a simulator, but it is only for power supplies.
