EE-Sim Migration Guide

EE-Sim has been retired

As of July 15, 2026, EE-Sim is no longer available. All EE-Sim URLs now redirect to Power Studio Designer. Your supported designs have been imported — sign in and go to Library > My Designs to find them. Designs we can't import yet appear as Pending while we continue onboarding them.

Why is EE-Sim being retired?

EE-Sim is a third-party, vendor-hosted tool that has reached end-of-life. The vendor's shutdown of the platform accelerated the transition to Power Studio Designer, which was already the planned successor. Your existing designs have been preserved and are available in Power Studio Designer using the same MyAnalog account.

Power Studio Designer is ADI's next-generation, browser-based power design tool and the direct replacement for EE-Sim. It covers the same DC-DC power supply design workflows with several improvements.

What's Improved

  • 374+ solutions across a unified Maxim and LT catalog (vs EE-Sim's 250+ ICs)
  • Instant analysis — no waiting for simulation runs; efficiency, loss, and loop stability are computed on demand
  • Parametric sliders — sweep temperature (-40°C to 125°C) and input voltage with live chart updates
  • Multi-Vin visualization — efficiency and loss charts plot Vin(Min), Vin(Nominal), and Vin(Max) simultaneously
  • Component editing from analysis — click "Edit part" directly in the loss breakdown table
  • Design health indicator — automated validation flags issues before you run analysis

What's Different

  • Analytical engine for instant results — Power Studio Designer computes built-in results on demand and exports to LTspice/SIMPLIS for circuit-level simulation. Online simulation with LTspice and SIMPLIS is a planned feature.
  • Multiple design options — the same requirements-driven workflow generates several valid designs across acceptable parts, so you compare and choose rather than accepting a single result
  • No general-purpose waveform viewer — replaced by purpose-built analysis views with integrated metrics and parametric controls

OASIS

The OASIS desktop simulator continues to be available for offline simulation workflows and will be maintained as part of ADI's power management tools portfolio.

Quick Start

  1. Open Power Studio Designer
  2. Sign in with your ADI MyAnalog account (the same account you used for EE-Sim)
    • Go to Library > My Designs to find your imported EE-Sim designs
    • From Start, click Create New Design to get customized solution options from your requirements
  3. From Library, click Create Design on any solution to open it in the editor
    • Adjust requirements, swap components, run analysis, export BOM or simulation files

Next Steps

  • Getting Started video — a quick tour of Power Studio Designer
  • Your Designs — find your imported EE-Sim designs and track any that are Pending
  • Workflow Comparison — see how your EE-Sim workflows map to Power Studio Designer
  • FAQ — common questions about the transition

Your Designs

Power Studio Designer has imported the EE-Sim designs it currently supports — you don't need to export or import anything yourself. Designs that can't be imported yet appear as Pending while we continue to onboard them.

Where to Find Them

  1. Sign in to Power Studio Designer with your MyAnalog account (the same one you used for EE-Sim)
  2. Navigate to Library > My Designs
  3. Your imported designs appear alongside any new designs you create in Power Studio Designer

My Designs in the Library

Imported Designs

If your design uses parts that are in the Power Studio Designer unified catalog, it has been imported and is fully editable — you can modify components, adjust requirements, run analysis, and export just like any other Power Studio Designer design.

Pending Designs

Power Studio Designer doesn't yet support every EE-Sim part. Designs that use a part we can't import yet appear in My Designs with a Pending status.

  • Pending designs can't be opened, edited, or analyzed yet — they haven't been imported
  • We're continuing to onboard parts and will eventually import all designs
  • Need a Pending design sooner? Hover the Pending pill and click Request Import to open a Technical Support request to prioritize importing that design

No action is required — we'll import your Pending designs over time. Requesting import just helps us prioritize the ones that matter most to you.

Support / Configuration Components (Planned)

Power Studio Designer doesn't yet support editing of Support / Configuration components. These are components that configure the IC but don't affect loop response — things like BIAS capacitors, pullup resistors, SS capacitors, etc.

  • For imported EE-Sim designs, the values and vendors for these components have been preserved
  • This data will become accessible once support for Support / Configuration components is enabled
  • No action is needed on your end — your data is preserved and will appear automatically when this feature is available

Same Account

You do not need a new account. Your existing ADI MyAnalog credentials work in Power Studio Designer. Corporate SSO (Azure AD) is also supported.

Can't Find a Design?

  1. Confirm you're signed in with the same MyAnalog account you used for EE-Sim
  2. Check Library > My Designs
  3. If a design uses a part we can't import yet, it will appear with a Pending status
  4. If a design still doesn't appear, contact Power Studio Designer Technical Support

Workflow Comparison

This page maps your EE-Sim workflows to their Power Studio Designer equivalents. The same tasks are all possible — some are even easier.

Finding a Part

EE-Sim: Solution Finder validates your requirements and ranks ICs by efficiency, size, and cost.

Power Studio Designer: The Library serves the same purpose.

  1. Navigate to the Library tab
  2. Enter your requirements: Vin (min/nom/max), Vout, Iout
  3. Filter by topology, integration type, function
  4. Use the Design Criteria sliders to filter by efficiency, BOM cost, and area
  5. Each solution card shows a schematic preview, efficiency percentage, and board area

Solution Library showing 374+ solutions with filtering

The library contains 374+ validated solutions across the unified Maxim and LT catalog. Results update as you adjust requirements. Toggle between grid and table views.

Creating a Design

EE-Sim: Enter Vin, Vout, Iout. Tool generates a single complete schematic with auto-selected components.

Power Studio Designer: The same requirements-driven workflow is available — enter your specs and Power Studio Designer generates a complete schematic with selected components. The difference is the engine and the result:

  • A unified design engine — a hybrid of the EE-Sim and LTpowerCAD approaches — produces fast, accurate solutions
  • Rather than a single result, Power Studio Designer generates multiple valid designs across acceptable parts, so you can compare options and pick the one that best fits your priorities

Loaded design with full schematic and requirements sidebar

The Design Requirements sidebar (shown on the left) gives you full control:

  • Input voltage (Minimum, Nominal, Maximum)
  • Output voltage and current
  • Voltage ripple targets
  • Load transient parameters
  • Switching frequency
  • Ambient temperature
  • Design priority (Balanced, Efficiency, or Size)
  • BOM cost priority

Click Update to propagate changes. The schematic, component recommendations, and analysis results all update accordingly.

Working with the Schematic

EE-Sim: View schematic online (limited editing) or use OASIS desktop for full editing.

Power Studio Designer: The schematic editor is interactive and web-based:

  • Full circuit visualization with all components, connections, and values
  • Click any component to open its selection panel — browse alternatives filtered by your design's requirements
  • Smart recommendations account for ripple current, saturation current, thermal limits, and package size
  • Changes to components update performance metrics in real time
  • Design Status indicator confirms your design is healthy and provides recommendations for design optimizations

Design tab with component selection panel open on L1

For advanced schematic editing (adding arbitrary components, wire routing, custom circuits), export to LTspice.

Analyzing Efficiency

EE-Sim: Run "Efficiency vs Load" simulation. View single efficiency curve. Wait for results.

Power Studio Designer: Navigate to Analyze > Efficiency and Loss. Results appear instantly — no simulation run required.

Efficiency analysis with multi-Vin curves, loss breakdown, and parametric sliders

What you get:

  • Efficiency vs Load chart — three curves plotted simultaneously for Vin(Min), Vin(Nominal), and Vin(Max)
  • Total Power Loss vs Load chart — same three Vin variants
  • Loss Breakdown panel — donut charts showing efficiency and loss at max load, plus a per-component loss table with an Edit part button for direct component swapping
  • Parametric sliders — adjust input voltage or ambient temperature (-40°C to 125°C); charts update live

No need to re-run simulations for each operating condition.

Checking Loop Stability

EE-Sim: Run frequency domain simulation to generate Bode plot. Run load transient simulation for step response.

Power Studio Designer: Navigate to Analyze > Loop and Load Transient.

Loop gain Bode plot and load transient analysis

Bode plot:

  • Gain (dB) and phase (degrees) vs frequency
  • Phase margin, gain margin, and crossover frequency displayed
  • info link shows detailed stability analysis

Load transient:

  • Output voltage response to a load current step
  • Overshoot, undershoot, and settling time visible

Load step parameters are configurable in the Design Requirements sidebar.

Exporting BOM

EE-Sim: Export Bill of Materials with manufacturer, part number, and quantity.

Power Studio Designer: Select Export > BOM from the design view. The exported BOM (CSV or Excel) includes:

Field Description
Reference Component designator (L1, C1, R1)
Part Number Manufacturer part number
Manufacturer Component manufacturer
Value Nominal value (4.7 uH, 22 uF)
Key Specs Voltage rating, DCR, ESR, package
Quantity Number required

Note

Support / Configuration components are not yet supported in Power Studio Designer. For imported EE-Sim designs, this data has been preserved and will be included once support for these components is enabled.

Running Simulations

EE-Sim: Up to 6 simulation types run inline using SIMPLIS. Results appear in the Webscope waveform viewer.

Power Studio Designer takes a different approach:

Built-in analytical engine handles the most common analyses instantly:

  • Steady-state efficiency and power loss
  • Frequency domain (Bode plot, phase/gain margin)
  • Load transient response

No simulation run needed — results compute on demand and update live when you change parameters.

For advanced simulation, export your design:

Target Best For Advanced Analysis
LTspice Offline simulation for LT and ADI parts Startup transient, fault conditions, Monte Carlo, temperature sweeps, noise analysis
SIMPLIS/OASIS Offline simulation for Maxim parts Fast switching simulation with piecewise-linear models, periodic operating point, AC/loop analysis

The export includes the complete netlist, component values, IC model, and suggested simulation configuration.

Note

Online simulation with LTspice and SIMPLIS directly in Power Studio Designer is a planned feature. Today, export your design to run these simulations offline.

Saving and Versioning

EE-Sim: Cloud-based save, track changes, compare design versions, share via link/email/team.

Power Studio Designer:

  • Save — Save button with dropdown (Save, Save As)
  • Version History — Panel showing saved versions with restore controls
  • My Designs — Tab in the Library showing all your saved designs
  • Sharing — Secure cloud-based sharing workflow rather than insecurely emailing designs
  • Cloud Storage — Designs stored in secure, encrypted cloud storage

Frequently Asked Questions

Why is EE-Sim being retired?

EE-Sim is being retired for two reasons. First, ADI Power Studio Designer is our next-generation power design environment and the planned successor to EE-Sim. Second, EE-Sim is a third-party, vendor-hosted tool that has reached end-of-life, and the vendor's shutdown of the platform accelerated the transition timeline. Your existing designs have been preserved and are available in Power Studio Designer using the same MyAnalog account.

Where are my designs?

Power Studio Designer has imported the EE-Sim designs it currently supports. Sign in and go to Library > My Designs to find them. Designs that use parts we can't import yet appear as Pending — hover the Pending pill and click Request Import to ask us to prioritize importing one.

Do I need a new account?

No. Continue using the same MyAnalog account you used with EE-Sim. Corporate SSO (Azure AD) is also supported.

Are all EE-Sim parts supported?

Not yet. Power Studio Designer currently has 374+ solutions across the unified Maxim and LT catalog. Part support is being expanded on an ongoing basis, and additional parts will continue to be onboarded. If a design uses a part that isn't yet supported, it appears as Pending until we import it. You can hover the Pending pill and click Request Import to prioritize it.

What does a "Pending" design mean?

A Pending design is an EE-Sim design that Power Studio Designer can't import yet because it uses a part that isn't in the unified catalog. Pending designs appear in Library > My Designs but can't be opened, edited, or analyzed until they're imported. We're continuing to onboard parts and will eventually import all designs. To ask us to prioritize a specific design, hover its Pending pill and click Request Import, which opens a Technical Support request.

Why are my Support / Configuration components not populated (BIAS capacitors, pullup resistors, SS capacitors, etc.)?

Power Studio Designer doesn't yet support editing of Support / Configuration components — components that configure the IC but don't affect loop response, such as BIAS capacitors, pullup resistors, SS capacitors, etc. For imported EE-Sim designs, the values and vendors for these components have been preserved and will become accessible once these components are enabled. No action is needed on your end.

What if I can't find a design?

Confirm you're signed in with the same MyAnalog account used for EE-Sim and check Library > My Designs. If a design uses a part we can't import yet, it will appear as Pending. If a design still doesn't appear, contact Power Studio Designer Technical Support for help.

Why are my efficiency numbers different from EE-Sim?

Power Studio Designer uses real-time analytical calculations rather than a full circuit simulation for built-in results, so values may differ slightly from EE-Sim's SIMPLIS-based simulations. For exact correlation, export your design to LTspice or SIMPLIS and run a full simulation.

Can I run simulations online in Power Studio Designer?

Not yet. Power Studio Designer uses a built-in analytical engine for instant results (efficiency, loss, loop stability). For full circuit simulation today, export your design to LTspice or SIMPLIS. Online simulation with LTspice and SIMPLIS is a planned feature.

Why does Power Studio Designer look different?

Power Studio Designer is a modern, IC-level power design environment with guided workflows, component recommendations, and instant performance analysis. Some tasks are presented differently than in EE-Sim — watch the Getting Started video for a quick tour, or see the Workflow Comparison for a detailed mapping.

Can I still use OASIS?

Yes. The OASIS desktop simulator continues to be available for offline simulation workflows and will be maintained as part of ADI's power management tools portfolio. You can also export designs from Power Studio Designer directly to SIMPLIS format.

What about bench measurement correlation?

EE-Sim's OASIS could import bench data and overlay it on simulation results. Power Studio Designer does not have this capability. Use LTspice alongside your bench equipment for manual correlation.
