Hit Run, wait for a few seconds to capture some data then hit Stop. Set Channel B mode to Hi-Z to measure the voltage across the diode. Set the Mode to SVMI and the Shape to triangle. Set Channel A AWG Min value to 0V and Max value to 5V. Now we can run the simulation for 20 mSec and we should get a plot much like we got in ALICE of the actual circuit.

Note that all you have to do is specify the name of the file to use in each of the PWL sources. We need a second PWL source, named CHB-Meas, that will simply play back the measured CH-B voltage data for comparison to the simulated voltage waveform on node CHB. We have one PWL source, named CHA-Meas, that will be the input to the RC circuit.

Now we are all set to enter the example circuit in LTspice. Each PWL data file can contain data for just one source.įor this example we will use this function twice to save the channel A voltage trace data into a file named cha-out.txt and the channel B voltage trace data into a file named chb-out.txt. The program prompts for which channel's data you want to save. Under the File drop down there is an option to Save PWL Data. įor the next step save the waveform data in a form that LTspice can read in as points for a PWL source. If we now set the CH B mode back to Hi_Z and reconnect it to the capacitor and hit Run we should again see something like figure. Still using the simple RC circuit example. We can then use them as PWL sources within a simulation so they can be used as either inputs to the simulated part of the circuit or compared to the simulated output voltage waveform.

In this part of the activity we are going to go over a simple example showing how to save the output waveforms from ALICE desktop in a format that LTspice can use. Sometimes we might need to use the output generated from an actual circuit as the input stimulus for part of the overall design that might not be built yet. We will name the output of the pulse as CHA and the voltage on the capacitor as CHB to match the ADALM1000 connections. A PULSE source is used to simulate the CHA output of the ADALM1000 and a 2.5 V DC source is used to simulate the fixed 2.5 V rail. The resistor, R1, we are using is 10K ohms and the capacitor, C1, is 0.22 uF. The first thing to do is enter the following simple RC circuit, shown in figure 1, into LTspice.

By comparing simulated and actual results you can get the most out of this powerful combination of software and hardware. In this Blog entry we are going to go over a simple example showing how to run a simulation in LTspice, export the simulated voltage waveforms and then load them into ALICE so they can be compared to the measured voltage waveform you get on the actual circuit. The ADALM1000 and ALICE Desktop is a multi-purpose and incredibly useful set of measurement tools for testing electronic circuits. Theĭesigned and implemented Arbitrary signal Generation System is stand-alone and doesn’t require the support of any computer hardware or software, as was needed in earlier attempts It has been concluded that virtually any periodic signal can be generated using the technique developed.Circuit simulators like LTspice, and others, are useful tools for testing out electronic circuit experiments before actually constructing the circuit. Conclusion: Excellent accuracy with zero error is achieved. Was found that all the signals generated showed precisely zero error and the signal generated wasĮxactly the same as the desired one. Results: The simulation results demonstrated both the digital and analog versions were presented. The design had been done using state-of-the-art high levelĭesign techniques and has been targeted to the latest available FPGA chips from Xilinx and Altera. Approach: A new approach for designing arbitrary signals utilizing Walsh and The proposed system utilizes orthogonal functions to generate a variety of periodicĪrbitrary signals. We present modeling, simulation and prototyping of a novel periodic arbitrary signal generation system However, all of them suffer from many drawbacks. Several different techniques utilizing both analog and digital approaches are being usedįor the generation of periodic signals. Problem statement: Arbitrary signal generators play an important role in manyĪpplications.
