Created using Figma. First off, are you or your organization already using Altium Designer? In that case, why do you need an evaluation license? I need the latest Altium Designer installer.

I want to evaluate the latest features. I want to view a design file. Got it.There are three approaches to annotating a design. The choice of Annotation Tool depends on a number of factors including the type of design, personal preference, and company policy and procedures. Schematic Level Annotation uses a purely logical view of the design to determine component designators.

This allows positional information to be effectively encoded into a component's designator and can be very helpful when debugging an assembled PCB.

Board Level Annotation provides a mapping between designators used in the schematic logical design and their real world counterparts on the PCB physical design.

While Board Level Annotation can be used in any design, it is especially useful for multi-channel designs or designs that incorporate device sheets where the designators cannot be edited on the device sheet itself.

In this way, the entire design can be re-annotated without actually modifying the original device sheet s. Annotation text file. It includes additional keywords for customizing naming schemes and allows them to be applied to all or only a select range of parts. The Annotate Schematics command systematically assigns designators to all or selected parts in selected sheets of a project and ensures that designators are unique and ordered based on their position.

The Annotate dialog is launched from the Annotate Schematics command. The Annotate dialog is divided into two primary regions:. Positional annotation is directed through the Order of Processing option.

The four options shown below are available to control how schematic documents will be scanned. Matching components into multi-part packages. When using multi-part packages, it is often desirable to pack as many parts into the minimum number of physical parts since this minimizes the overall BOM cost of the design. In order for multi-part packing to be included as part of the annotation process, the Complete Existing Packages drop-down must be set to something other than None.

For non-homogeneous multi-part components, ensure the Locked icon is closed to prevent sub-part changes during annotation.

The default settings in the Annotate dialog are to complete existing packages by Library Reference and Comment, however, you can select any combination of parameters. If the Strictly checkbox is enabled for a Component Parameterall components must have that parameter matched into a package. Components that do not have this parameter are annotated as individual components and are not packaged. Consider a design with eight OR Gates and eight resistors as shown in the image below.

The resistors have no such parameter. Enabling the checkbox for QuadOrGate in the Component Parameter control will ensure that this parameter is used to control how components are packaged; in this case, the Strictly check box is not enabled. Any remaining components that do not have the QuadOrGate parameter will be packaged together. In this case, the resistors are packaged together since their common attribute is that they do not contain the QuadOrGate parameter.

Example of packaged components when the Strictly option is unchecked. If the same design is annotated but the Strictly option is checked, only those components that have the QuadOrGate parameter will be packed.

In this case, the OR gates will be packed but the resistors will be left unpacked. Example of packaged components when the Strictly option is checked. Specifying the scope of annotation. Click the Update Changes List button to update the Proposed Change List so that all designator changes can be reviewed prior to being applied.

Only designators that have not previously been set i. Resetting designators prior to applying the annotation settings. The Proposed Change List lists all designators for the parts contained within the sheets selected for annotation. For each entry, details of the Current and Proposed Designator values are included along with the component's Sub part and the source Location of Part.

Similarly, checking the Sub box will prevent that specific multi-part component from being updated.The Sheet Numbering For Project dialog.

This dialog provides controls to quickly number the constituent schematic sheets in the active design project. Sheet and Document Numbering allows you to take control over the sheet designation and store them as parameters within the respective schematic documents. The dialog is accessed from the Schematic Editor by clicking Tools Annotation from the main menus.

The SheetNumber and DocumentNumber fields can be edited directly in the grid. Click once to focus the cell, then click again to enter edit mode. For the latter, select the cells required then right-click on one cell and choose the Edit command. Enter the new value then press Enter - the value will be used for each cell in the selection. A field that has been modified with respect to its value will be distinguished by the use of a blue triangle in its top-right corner.

Changes will be effected once the OK button is clicked. If an organization has a specific number or naming system that cannot be automated through either the Auto Sheet Numbering or Auto Document Numbering controls, custom sheet names and numbers can be written directly into the SheetNumber or DocumentNumber fields.When schematics were originally captured on paper, it was often on a single sheet of paper large enough to fill a big drafting table, which was reproduced on a dedicated, large-format copier.

Times have changed, now schematics are captured on a desktop PC, stored on a server, and printed on a small-format laser printer. This change means that even a simple design can be more easily displayed and understood if it is presented on multiple schematic sheets. Even when the design is not particularly complicated, there can be advantages in organizing it across multiple sheets. For example, the design may include various modular elements. Maintaining these modules as individual documents allows several designers to work on a project at the same time.

Breaking the design into logical modules greatly enhances the readability of the design too, an important consideration for those that need to read and interpret the schematic later in the life of that product. Another advantage is that when a design is structured over a number of sheets with fewer components on each, small format printing, such as laser printers, can be used.

Your choice will vary according to the size and type of each project, and your personal preferences. This article focuses on the structural relationships between the sheets, how it works and the tools and techniques available to create a multi-sheet design. As mentioned, as the designer you need to decide how the schematic sheets are organized, and how the connectivity is established between those sheets.

These are not separate decisions though, as you choose the structure you will also need to choose how the connections between those sheets are going to be created. There are two approaches to structuring a multi-sheet design: either flat or hierarchical.

The technique used to connect a child sheet to the parent sheet is the same for both flat and hierarchical designs - it is how the connectivity is created that determines if it is a flat or hierarchical design.

You can think of a flat design as if a large schematic sheet has been cut up into a number of smaller sheets - in a flat design all sheets exist on the same level. The connectivity in a flat design is created directly from any sheet to any another sheet - this type of connectivity is referred to as horizontal connectivity.

Annotating the Components

The use of a top sheet is optional in a flat design. If one is included, it will have a sheet symbol for each of the sheets in the design, but cannot include any wiring.

Both of the images above show a flat design, the version on the left does not have a top sheet, the version on the right does. For a small design that only has two or three schematic sheets in it, you might decide that a top sheet does not add any value. Once the sheet count gets higher, a top sheet can help the reader understand the functionality of the circuit design from the way that the logical blocks Sheet Symbols are arranged on the sheet.

All sheets in the design appear at the same level in the Projects panel because there is no hierarchy.

Numbering the Sheets

As in a flat design, the child sheet is identified by defining its filename in the sheet symbol.Parent page: More about Schematics.

The use of a top sheet is optional in a flat design. If one is included, it will have a sheet symbol for each of the sheets in the design, but cannot include any wiring.

There can be any number of sheets in a flat design. First image - the flat design has no top sheet; second image - the same design has a top sheet. Note that the top sheet has no wiring. It simply shows the sheets in the design. Both of the images above show a flat design, the version on the left does not have a top sheet, the version on the right does.

For a small design that only has two or three schematic sheets in it, you might decide that a top sheet does not add any value. Once the sheet count gets higher, a top sheet can help the reader understand the functionality of the circuit design from the way that the logical blocks Sheet Symbols are arranged on the sheet. All sheets in the design appear at the same level in the Projects panel because there is no hierarchy.

A hierarchical design is one that has Sheet Symbols to create the parent-child type relationships between the sheets, andthe connectivity is through the Sheet Entries in those Sheet Symbols - not directly from the Ports on one sheet to the Ports on another sheet. As in a flat design, the child sheet is identified by defining its filename in the sheet symbol.

In a hierarchical design, that child sheet can also include sheet symbols, referencing lower-level sheets, thus creating another level in the hierarchy.

The image below shows a hierarchical design, with 3 levels in the hierarchy. In a hierarchical design, the structure shown in the tree is determined by the parent-to-child relationships created by the sheet symbols.

In a hierarchical design, a signal on a child sheet leaves the sheet via a Portwhich connects upward to a matching Sheet Entry on the parent sheet. The parent sheet includes wiring that carries the child signal across to a Sheet Entry in another Sheet Symbol, it then travels down to a matching Port on the second child sheet, as shown in the image below.The Sheet Numbering For Project dialog.

Conceptually, it is therefore related to the general concept of design annotation. Use the Sheet Numbering For Project dialog to number and organize the schematic sheets in a project.

Click on the Update Sheet Count button to tally the total number of sheets in the current project and place the result in the SheetTotal column. The sheet count will be the total number of sheets in the project regardless of the numbering scheme selected in any of the previous controls.

When Device Sheets are set as editable, the cross-hatching is removed and Sheet and Document Numbering can be configured as normal.

Cross-hatching indicted the device sheets are set to read-only and cannot be renumbered. This ensures that annotation information and settings are remembered across project editing sessions. The Annotate Compiled Sheets dialog treats Device Sheets like other any other sheet in the design project and annotates them according to the Annotation options.

For example, consider a design that includes a schematic document called Input channel. SchDoc will be instantiated eight times i. Click on the Annotate Sheet drop-down to set the Annotate Sheet options. Setting the Compiled Sheet Annotation options.
