Maxim Integrated Page 15 of 55 3.6 Edit a Schematic 3.6.1 Edit Component Properties Change the properties of the components in your schematic as described below. Some components are considered critical to the design and other parts are not. When adjusting critical component values, the application flags them for your attention by applying a highlight color to both the component you changed and the Recalculation button. This change in appearance alerts you to edits that impact the values in other components. These impacted values can be recalculated. 1. 2. 3. 4. a. b. c. d. e. 5. 6. 7. 8. NOTE: Each time you recalculate, a new version of your schematic is added to the version history for the current design. Maxim Integrated Page 16 of 55 Click the part number or PDF icon to view the data sheet. Click Save Design or the Save button at right to save your new design. When the Recalculation tab is highlighted, click it to perform adjustments to your schematic based on pending changes you made to critical components. As the Legend reminds you, critical components with changes are flagged in the diagram in orange (C1). Critical components with locked values appear in green (L1). Critical components that have been changed and are locked appear in both colors (C7). Double-click or right-click a component to edit its properties or change vendors. Critical components feature an orange banner at the top of the properties window. A component shows its locked or unlocked state with a checkbox on the properties window and a padlock icon that appears in the locked or unlocked state. Use the new schematic toolbar to apply annotations, zoom and pan, and export the schematic image. 3.6.2 Select a New Vendor Part Component values, secondary parameters, and even specific manufacturer part numbers for most components in the schematic can be changed. Choose from a library of appropriate purchasable components or just supply the key values for a component without selecting a purchasable part. 1. 2. 3. a. b. Maxim Integrated Page 17 of 55 c. d. e. f. g. Applying filters to select a different vendor part is demonstrated in the graphic on the next page. Maxim Integrated Page 18 of 55 Selected Part: The top of the window shows the currently selected part. Available Filters: This section lists search options. Default settings are based on the design requirements that you entered for your design before generating the schematic are made to the filter settings such as widening a filter, you can get parts that no longer satisfy the needs of the circuit. Do so with care and proper circuit design knowledge. For items with sliders, either move the sliders or modify the data in the boxes at either end of the sliders. After making any changes to the filter settings, click the Apply Filters button to find the parts that match your newly modified criteria. Click Reset to restore default values and Clear All to remove all values, which allow you to start the filtering process from scratch. Applied Filters: This section reminds you of the search criteria used to generate the current list of matching parts. Results: Click Link for a part number to learn more about the product and manufacturer. Click on the part number or description to replace the currently selected part with this new one. Search: Search for a specific component (filters are not applied). 3.6.3 Annotate a Schematic Using the Toolbar Use the convenient toolbar to annotate, markup, adjust the view, resize, or export an image of your schematic. 1. 2. 3.

Page 23 of 55 Toolbar Button: Function: Zoom to All Components Fits the entire schematic onto the current page. The image appears smaller because all components are included. Zoom Out Zooms out one level. With each click, the image appears smaller because the view is relative to a point that is going out, away from the schematic. Zoom In Zooms in one level. With each click, the image appears larger because your view is relative to a point that is going in, closer to the schematic. Area Zoom Tool Defines an area in the schematic, then magnifies it (zooms in) to show as much of it as possible in the current view. Examples: In this example, the user defines the rectangle around the Design notes text and arrow (top) with the Area Zoom Tool before it expands (bottom). Undo Reverses the last action. This command is not always available. Redo Reverses the last undone action. This command is not always available. Maxim Integrated Page 24 of 55 Toolbar Button: Export Schematic Image 3.6.5 Function: Examples: Choose an image format for exporting the schematic to an image file. Import the image file to Word, PowerPoint, and other applications. Version History The DC-DC Converter Design tool automatically stores versions of your design as you work. Changes in design requirements and recalculated schematics trigger a new major version; changes in device values are recorded as minor versions. While working on your design, you can go back at any time and retrieve any of these versions with all their values and simulation results preserved. When you save your design, all versions of the design are also saved with it. NOTE: Although simulation data is not saved when you exit your design, having all versions of the design saved enables you to rerun simulations if needed. Knowing your designs are saved with such an audit trail enables you to work with confidence. 1. 2. 3. a. Maxim Integrated Page 25 of 55 b. c. 4. a. b. c. NOTE: When you roll back to a previous version, all subsequent versions are lost. As a precaution, click Save As to make a backup of the latest version. Then, roll back without concern for the lost history. When you save a design, it is saved along with all its history but not the simulations for each step in the history. It is only while working in a single session on a design that its entire history for that session is available. When you save a design, no matter where it is in the history, only that specific version is saved (without the simulation data). 3.7 Simulation and Analysis 3.7.1 Run a Simulation and Generate Waveforms The DC-DC Converter Design tool provides six different analysis types to evaluate your designs. Each type is preconfigured to provide useful waveforms; however, these settings can be overridden. There is no need to learn to use the underlying simulator because this tool takes care of that for you. Run any combination of the six different simulation types. The results from each simulation type are displayed on their own separate tabs. To set up and run a simulation: 1. 2. 3. 4. a. b. c. d. e. Maxim Integrated Page 26 of 55 f. 5. 6. 7. 8. \ On the Schematic page, click the Simulation button. Select the check box for each simulation type you want to run. In this example, the Load Step, Steady State, and Line Transient runs next time the Run Simulations button is clicked. Click a tab to customize the simulation settings. When editing field values, warning text appears to alert you when a setting is too low or too high. Invalid entries appear in red. These values must be corrected. You cannot run a simulation with invalid entries. Click Run Simulations to run each checked simulation. To view simulation results, click the corresponding teal link in the upper right area of the window. Click Save and Close to save your simulation selections for your current session. If you click Save and Close, invalid entries (in red) are not saved. The field values revert to their last valid entries. Maxim Integrated Page 27 of 55 3.7.2 View Simulation Waveforms After clicking Run Simulations (see previous section), each completed simulation type displays a link to show the results. For example, click AC Loop or Load Step. When you click the results link, expect to see the following graphs on their own separate tabs in a separate Webscope waveform viewer browser window for each test: ▪ Load Step: The many time-domain voltages and currents are grouped logically. While the groupings can vary, the most common groups are: ▪ IC: Displays voltages of various pins on the IC that do not belong in the other groups. ▪ Input: Displays current and voltage waveforms related to the input. ▪ Switching: Displays current and voltage waveforms related to the switching transistors and nearby circuitry. ▪ Output: Displays current and voltage waveforms related to the output. ▪ AC Loop: This simulation produces the simplest set of waveforms. ▪ Bode: Displays a Bode plot of the feedback loop for each output. Frequency is plotted on the horizontal axis using a logarithmic scale. The first vertical axis is the gain in decibels (dB). A second vertical axis is phase in degrees. ▪ Steady State: The many time-domain voltages and currents are grouped logically.

NOTE: Some parts may not utilize all six (6) analysis types. 3.7.3 Customize the Waveform Viewer Output Use the Webscope waveform viewer to see the simulation results in a graph with table entries appearing at the bottom. The waveform viewer does a smart autoscale for each vertical axis. Rather than using the maximum and minimum Y values from the waveforms as the visible scale limits, it chooses slightly larger limits so that the major divisions have relatively simpler values (with fewer nonzero significant digits) and aligns the grids for multiple vertical axes. The autoscale feature improves the visual appearance of the waveforms and makes it much easier to work with them. Refer to the following sections to customize the waveforms: ▪ 3.7.3.1 Customize the Waveform Tabs ▪ 3.7.3.2 Customize the Waveform Axes and Markers Maxim Integrated Page 28 of 55 ▪ ▪ ▪ ▪ 3.7.3.3 Capture Precise Waveform Data Using Markers 3.7.3.4 Customize Your View of the Waveform Graph Using the Toolbar 3.7.3.5 Add a New Waveform to the Current Graph 3.7.3.6 Add a Custom Tab to the Waveform Simulation Results 3.7.3.1 Customize the Waveform Tabs 1. 2. 3. a. ▪ Set the Graph Stack Method to Not Stacked to plot all the output in the same graph. ▪ Set the Graph Stack Method to Stacked to plot each waveform on individual graphs with the graphs stacked vertically. ▪ Set the Graph Stack Method to Stacked for all y-axes to group the graphs by voltage (V) and Current (A). b. c. d. 3.7.3.2 Customize the Waveform Axes and Markers Customize the appearance of the axes and markers. 1. a. b. c. d. e. f. 2.
