TDFS Part 1 - Gain and Phase Measurements for Switching and Mixed-Signal Circuits and Systems

SystemVision Cloud provides a family of measurement models that perform “Time Domain Frequency Sweep” (TDFS) analysis. They measure the frequency response of many circuits and systems for which traditional “AC” or frequency-domain simulation is not possible. This includes:

Import Your SystemVision Cloud Design Into the PADS PCB environment

SystemVision Cloud is designed to work with the Mentor PADS PCB tools.  If you have the PADS PCB tools, you can install an import tool into the schematic capture environment.  Using this import tool, you can login with your SystemVision Cloud account, from within the schematic environment, browse for your online designs, and import them into a PADS schematic.  

For an overview of this capability, visit the SystemVision PADS AMS Cloud page.

More Motor Models … Switched Reluctance and Stepper

In my previous blog, “Mechatronics Engineers … Start Your Motors”, I mentioned that we were working on two additional motor types, a Switched Reluctance Machine (SRM) and a Stepper Motor.

Breadboard Power Supply


While working from home, a PCB designer may not have access to expensive power supplies to test fairly simple boards. By using low-noise linear voltage regulators, you can create a customizable power supply using 9 different voltages, ranging from 2.5 to 15 V. The power supply is equipped with an AC to DC converter, making it transportable for the do-it-all engineer. With easy access to this adjustable power supply, you do not need gigantic power supplies to complete your testing. 

The simulation model of the Adjustable Power Supply is shown below:

SPICE modeling in SystemVision Cloud

We are pleased to announce that SystemVision Cloud now supports import of SPICE subcircuits and individual ".model" statements as a way to specify a model for use in SystemVision.  Simply choose the Create New Component > From SPICE menu when you are editing a design.

Watch this short video to see a demonstration:

Electro-Hydraulic Component Modeling and System Simulation

The SystemVision Cloud Team is happy to announce that we’re adding new models to support electro-hydraulic system development. We’ve recently added basic hydraulic elements, such as a pump, valve and cylinder (or linear actuator). We will be adding many more models in the near future, but the examples shown in this blog demonstrate the broad range of electro-hydraulic motion and fluid control systems that are already supported.

Battery Model From Experimental Data

Many have observed that as a rechargeable battery is discharged the voltage that it supplies drops. Conversely, when it it recharged, the output voltage goes back up.  Wouldn't it be nice if you could measure this voltage, as a function of the state-of-charge (SOC), and use it to quickly make an accurate model for the battery?  This blog will show you how to do just this with SystemVision® Cloud.
