What does hierarchical design mean in Altium Designer?

What does hierarchical design mean in Altium Designer?

A hierarchical design is one that has Sheet Symbols to create the parent-child type relationships between the sheets, and, the connectivity is through the Sheet Entries in those Sheet Symbols – not directly from the Ports on one sheet to the Ports on another sheet.

How are NET identifiers used in Altium Designer?

There are a number of different net identifiers that can be used to connect between sheets. The Altium Designer Connectivity Insight functionality (part of the Design Insight feature) displays an instant view of the connection relationships within a project.

Do you need dynamic schematic in Altium Designer 20?

Now Altium Designer 20 will automatically compile your schematics as you create them. This is exactly the type of functionality you’ll find as part of the newest feature set in Altium Designer ®. The new dynamic schematic compilation features no longer force you to choose between flat vs. hierarchical schematics.

What do you mean by logical connectivity in Altium?

The software identifies these two net sections and connects them to form a single net. This type of connectivity is referred to as logical connectivity. Physical connectivity allows a user to follow each wire as they study the circuit, but a lot of wires can result in a dense and busy schematic.

How to change the number of sheets in Altium?

Drag and drop the sheets in the panel to change the numbering. The feature can be disabled in the Sheet Numbering For Project dialog or under the Options tab in the Project Options dialog (in the Netlist Options section). Click Auto Sheet Number in the Sheet Numbering For Project dialog to access a drop-down of sheet numbering options.

Where does the serial signal go in Altium repeated sheets?

However, one of the components in the sheet is a shift register that has a serial in and a serial out (for chaining multiple devices together). A single serial signal comes from the top level, and goes into the sheet to the serial in of the first sheet and the serial out is to go to the serial in of the next sheet etc..

What does managed sheets mean in Altium Designer?

The Vault-based system is called Managed Sheets, where you place an existing schematic from an Altium Vault, directly into the design being created. To learn more about Managed Sheets, refer to the Managed Sheets article.

How are duplicate nets created in Altium Designer 21?

A notification is also displayed in the Messages panel in the following format: NetName is the name of the affected net. Within each sheet, a unique net is created for each set of connected electrical objects. The compiler then checks the Net Identifier Scope to determine if the design is flat or hierarchical.

How to create device sheets in Altium Designer?

To learn more about Device Sheets, refer to the Device Sheets article. The Vault-based system is called Managed Sheets, where you place an existing schematic from an Altium Vault, directly into the design being created. To learn more about Managed Sheets, refer to the Managed Sheets article.

How are parent-child sheets defined in Altium?

This parent-child sheet structure can be defined to any depth, and there can be any number of sheets in a hierarchical design. The connectivity between the sheets is determined by the Net Identifier Scope. This is set in the Options tab of the Options for Project dialog.

How are sub-sheets referenced in Altium Designer 21?

Multiple sub-sheets may be referenced by a single sheet symbol. Separate each filename by a semi-colon in the File Name field. With the effective use of off-sheet connectors placed on the sub-sheets, you can spread a section of your design over multiple sheets treating them as though they are one giant (flat) sheet.

How to create a schematic symbol library in Altium?

To create a new schematic symbol library: Click File » New » Library » Schematic Library . An empty document called Schlib1.SchLib is created that displays a blank component called Component_1. Click File » Save As and rename and save the new schematic library document to a suitable location with an appropriate filename.

How do you rotate the sheet symbol Altium?

Press the Spacebar to rotate the sheet symbol counterclockwise or Shift+Spacebar for clockwise rotation. Rotation is in increments of 90°. Press the X or Y keys to mirror the sheet symbol along the X-axis or Y-axis.

How are nets created in Altium Designer 21?

The compiler then checks the Net Identifier Scope to determine if the design is flat or hierarchical. If the design is flat, the sheet-level nets are connected directly between the various sheets. the connectivity is created between the Sheet Entry and other connected electrical object on the parent sheet.

When do you get a schematic error in Altium?

It usually happens when the schematic was developed some time ago and the components on the server have been changed and a new revision was created during the schematic development cycle. It is extremely important to use the most current components in the design since they are free from errors that were in previous revisions.
