EE-Sim Migration Guide
EE-Sim has been retired
All EE-Sim URLs now redirect to the EE-Sim sunset page on analog.com. Use this guide to migrate your designs to Power Studio Designer.
EE-Sim has been replaced by Power Studio Designer, a modern power supply design and simulation tool. Power Studio Designer provides all of the capabilities of EE-Sim and more, including an improved simulation engine, expanded part coverage, and a redesigned user interface.
This guide walks you through the process of moving your existing EE-Sim designs to Power Studio Designer.
What is Power Studio Designer?
Power Studio Designer is a free, web-based tool for IC-level power supply design. It guides engineers from device selection through component optimization to performance validation — without installing software.
| Capability | Description |
|---|---|
| Solution Search | Filter ADI's power IC portfolio by Vin, Vout, load current, and topology |
| Interactive Schematic | Visualize and configure circuit designs with real-time feedback |
| Component Selection | Browse vendor-specific inductors, capacitors, and FETs |
| Efficiency Analysis | Evaluate power losses across the full circuit |
| Loop & Load Analysis | Validate stability with loop gain and phase margin |
| BOM Export | Generate a complete Bill of Materials |
| Simulation Export | Export to LTspice or SIMPLIS for offline analysis |
Quick Start
- Open Power Studio Designer
- Sign in with a free ADI myAnalog account
- Search for a solution by entering your input voltage, output voltage, and load current
- Select a recommended solution to open in the design editor
- Configure components, analyze performance, and export results

Key Improvements in Power Studio Designer
Guided Solution Explorer
Browse and filter ADI's unified power supply IC portfolio with guided workflows. Match requirements to recommended solutions with ready-to-use reference designs.
Interactive Schematic
Edit and customize circuit schematics in real time. Parameters, components, and vendor parts update instantly, making design exploration highly visual and interactive.
Efficiency Analysis
View efficiency, power loss, and loss breakdown at a glance. Charts and visualizations give immediate insight into design trade-offs across operating points.
Loop and Load Analysis
Visualize loop gain, phase margin, and load transients to validate stability and response, ensuring designs meet real-world performance needs.
Additional Benefits
- No installation required — runs entirely in the browser
- Expanded IC coverage — more ADI power ICs supported
- Real-time feedback — parameter changes update analysis instantly
- Modern UI — redesigned interface with Harmonic design system
- Export options — LTspice and SIMPLIS export for deeper validation
Exporting Designs from EE-Sim
If you saved designs in EE-Sim, you may need assistance retrieving them since the EE-Sim interface is no longer available.
How to Get Your Designs
Contact the Power Studio team for assistance:
- Email: power.studio@analog.com
- Subject: EE-Sim Design Export Request
Please include:
- Your EE-Sim account email address
- The design name(s) you need retrieved
- Any part numbers associated with your designs
Response Time
The team will respond within 2 business days with your exported design files.
What You'll Receive
Exported designs will be provided in a format compatible with Power Studio Designer import. See Importing to Power Studio for next steps.
Importing to Power Studio Designer
Power Studio Designer supports importing compatible EE-Sim design files.
Import Steps
- Open Power Studio Designer
- Sign in with your ADI myAnalog account
- Navigate to File > Import
- Select your exported EE-Sim design file
- Review and confirm the imported components
What Gets Imported
| Element | Imported? | Notes |
|---|---|---|
| Circuit topology | Yes | Schematic structure preserved |
| Component values | Yes | Resistor, capacitor, inductor values |
| IC selection | Yes | If part is supported in Power Studio Designer |
| Simulation results | No | Re-run analysis in Power Studio Designer |
| Custom annotations | No | Add notes manually after import |
After Import
Once your design is imported, you'll see it in the Design Canvas:
From here you can:
- Review the schematic in the Design Canvas
- Run Efficiency Analysis to validate performance
- Run Loop & Load Analysis to check stability
- Export to LTspice or SIMPLIS for time-domain simulation
Part Not Supported?
If your EE-Sim design uses a part not yet available in Power Studio Designer, contact power.studio@analog.com with the part number. Coverage is expanding regularly.
