Frequently Asked Questions

Where is the CircuitStudio documentation located?

CircuitStudio Documentation may be reached by pressing F1 while in a menu or dialog, or by navigating to the following address in your web browser:

Documentation: http://documentation.circuitstudio.com
Forums: https://www.element14.com/community/community/manufacturers/altium

How do I get CircuitStudio?

You can evaluate CircuitStudio with a 30-day free trial. To begin your free trial, install the software and then fill out the trial form that appears after the installation is complete.

Ready to purchase the software? Head on over to the Element 14 store.

Is CircuitStudio licensing time based or perpetual?

CircuitStudio licenses are perpetual and include 12 months of subscription (maintenance). Any updates including major product releases may be installed during the 12 months period. After 12 months, the software continues to work and may be reinstalled with versions prior to the subscription expiry date.

An additional 12 months of subscription (maintenance) can be purchased at any time using MFG PN 11-004-15-1 E.

Does subscription mean time limited?

No! CircuitStudio Subscription provides entitlement to updates so that when newer software is released you may stay up to date during the Subscription period. This is often referred to as Maintenance, but in Altium terminogy this is named Subsription. The software keeps working even after Subcription is expired because the CircuitStudio licenses are perpetual.

Do I need to be signed into my account to use my Standalone license?

With a Standalone license, the only time you need to sign in to your CircuitStudio account is when:

  • You are activating the license for the first time.
  • You are reactivating the license (required for example when you have deleted the license and don't have a backup of the license file).

Can CircuitStudio run with no Internet access?

Initial installation and license activation requires Internet access to complete the setup. Once setup is complete with the Standalone ALF license file activated, the software does not "phone home" and does not have any timers to prevent it from working.

Client-side license acquisition is managed by the user through use of a standalone licensing file (*.alf). This file can be saved, copied and backed-up as required. The .alf file is reusable on a home computer (in accordance with the EULA) simply by copying the file to a specific folder on that computer and then adding the file as part of Standalone License Configuration.

The software also uses Internet connections for some non-licensing purposes, for example, to load the Home page, to use Vault components, or search for Supplier Links. These functions won't work while there is no Internet.

Is CircuitStudio private or does it use Internet cloud-based projects or libraries?

CircuitStudio does not save any user data into the cloud. All projects and libraries are stored on your local drive.

If you create or edit a library component, it must also be stored on your local drive in SchLib or PcbLib files. These can optionally be compiled into an Integrated Library IntLib file. When the PCB is updated from the schematic, during the ECO process the footprint pattern is retrieved from the local PcbLib or IntLib file.

The Altium Content Vault may be used to place pre-made components onto your schematic, directly from the cloud, and these are then stored in the schematic document. When the PCB is updated from the schematic, during the ECO process the footprint pattern is downloaded onto the PCB directly from the cloud. The footprint is stored in the PCB document.

Please see the FAQ question about Vault Components, further below.

How do I Change Email Sign in or Notifications?

To change your sign in email address, please contact Element14 technical support https://www.element14.com/community/docs/DOC-73741 or the email listed under General Support Inquiry at the top of this page.

Within CircuitStudio on the Home screen there is a function My Account > Edit Account to change your email address. This email address is used for notifications from Altium about your CircuitStudio license, but does not change the sign-in email address.

Am I able to purchase an old version?

When you purchase the latest version of CircuitStudio you may use the new license on an older version of the software. The license activation downloads the appropriate *.ALF file for the version of CircuitStudio being activated. Old versions may be downloaded here:

http://altium-install.s3.amazonaws.com/CircuitStudio/CircuitStudioSetup.exe is version 1.2
http://altium-install.s3.amazonaws.com/CircuitStudio/CircuitStudioSetup1.3.exe is version 1.3

What can I do if the firewall is blocking the installation?

CircuitStudio uploads using SOAP over HTTP (port 80). If the firewall or proxy is blocking it, it's most likely because SOAP is blocked as a protocol. Try downloading the software from a different computer that is not blocked by firewall. You can also have your IT department open up the port to complete the download.

Is connection to the Altium Portal secure?

Yes, all communication with the Altium Portal is securely transmitted over https.

Will CircuitStudio run on Mac OS X or Linux or within VM's?

The CircuitStudio supported operating systems are Microsoft Windows version 7, 8, 10, preferably 64-bit. When using a Mac, use Bootcamp to enable Windows to be installed natively on the Mac. Bootcamp is a free download from Apple. Then boot into Windows to use CircuitStudio or boot into OS X to use the Mac software.

Alternatively, CircuitStudio will run in the popular virtual machines (VM's) such as Parallels, or VM Ware Fusion, or Oracle VirtualBox. Microsoft Windows needs to be provided to the VM when setting it up. This allows you to leave the host operating system such as OS X running and copy and paste files between the VM and the host.

The host machine, i.e. your physical computer, determines which VM software to select, i.e. for a Linux host you may choose VirtualBox. When using virtual machines, rotating your PCB in 3D may not be as fast or smooth because it is using a virtual graphics card, not the physical GPU on your machine. Also the overall performance may be a little slower. CircuitStudio relies on DirectX with 9.0c as the minimum specification, thankfully most GPU's and VM's support this now.

What component management methodologies are supported?

CircuitStudio offers the following component management methodologies:

  • Individual Component Libraries - Schematic Symbol (*.SchLib) and PCB 2D/3D Component Model (*.PcbLib) libraries.
  • Integrated Components
  • Vault Components

What do Integrated Libraries offer me, above and beyond standard libraries?

Standard schematic libraries allow you to attach PCB footprint models to components. Usually, each model link references a file (PCB library file) somewhere outside of the schematic library. So the schematic library saves a link, that is, instructions, on where to find the model you attach.

Periodically, CircuitStudio will need to locate these models - when you run a board update, for example, the linking instructions will be followed for all current footprints in your design. The search sequence for matching models starts with libraries in the current project, installed PCB libraries, and then any files found on the project search path.

The management of these separate source libraries is left entirely in your hands, meaning that CircuitStudio cannot offer any guarantees that your models will find matches. The links in schematic libraries are brittle, and are easily broken by everyday management tasks such as renaming folders on a hard drive or reassigning labels to a central server.

CircuitStudio has a solution to this problem - the Integrated Library. The integrated library includes not only the schematic library (or libraries), it also has all the associated model libraries bundled in. If a component came from an integrated library, CircuitStudio is guaranteed to find the right model if it can simply locate the integrated library it came from.

Because the components and models are entirely contained within a single .IntLib file, these libraries offer portability to designers who divide their work among different workstations, or who want to share their designs with others.

Simply installing the same, single file in the Libraries panel of any PC running CircuitStudio will mean that component-to-model links will remain secure (assuming, again, that components were placed in the design from that integrated library).

These libraries are also checked for integrity when they are compiled. That means they are not only checked for availability, but for correct pin mappings. Even designers who want to stay with discrete library files should compile their schematics in an integrated library package, if only to ensure that the source components will map correctly to the target models. Once satisfied, they can ignore the integrated library they created, and keep placing directly from their schematic libraries.

And what about Vault Components?

A significant advantage of using Altium Vault-based components is that they are managed for you, so you can be confident that they are up-to-date, available and correctly implemented. Making use of vault components also avoids the need to create and manage large collections of local component libraries.

Do I have to install and maintain an Altium Vault to use Vault Components?

Not at all. Vault components for use in your CircuitStudio designs are available solely from the Altium Vault technologies - the Altium Content Vault.

There is no additional installation of vault technology. You simply connect to the Altium Content Vault, then are able to browse and place its content directly into your designs, through the Vaults panel.

Open the Vault Explorer from the File menu. This allows Altium components to be placed directly onto your schematics. When you update your PCB, the footprint will be download from the Altium Design Content vault and will be saved into your CSPcbDoc file.

To enable this feature:
View > Start to show the Home page. My Account > Sign In with your CircuitStudio account and enable the two checkboxes.
File > System Preferences. Ensure the System > Account Management, Sign in when I start CircuitStudio option is enabled so that it will work next time.
File > System Preferences. In the Data Management > Vaults screen, click Add Altium Content Vault, press OK.

Note: At the time of writing (May 2017), the Windows 10 "Creators Update" OS Build: 15063.250 is not compatible with the Vaults panel and will cause a Blue Screen crash.

Note: CircuitStudio caters for the use of vault-based components in designs, but does not permit the creation, release, or modification of such components. In other words, data from the Altium Content Vault is strictly for consumption only.

How do I create a local .SchLib for components I placed on the schematic from the Vault?

Place a part from the Vault in a schematic, select it and copy (CTRL+C) then in the schematic library, right-click in the library panel's list of components and choose PASTE (or select that panel and use CTRL+V) it will copy the part into your own library. You can follow the same method for acquiring footprints from any design - including those imported from other tools.

How do I get help on commands, dialogs, panels, etc…?

Use the following methods to locate information on a particular resource:

  • Within the software, hover over a Ribbon button, menu command, dialog, panel, or design object, and press F1.
  • Search for your questions in the CircuitStudio documentation.

What support is available for importing from other design tools?

CircuitStudio accommodates importers for EAGLE (v6 and above), OrCAD (V7 through V16.2), and PADS PowerPCB, facilitating streamlined migration of designs created in these other tools. CircuitStudio 1.3 also supports importing of CircuitMaker (.CMpcbdoc) and Altium Designer v5 (.pcbdoc) files.

Which CAM output formats does CircuitStudio support?

CircuitStudio can output Gerber (RS-274X) and ODB++ CAM formats.

Can I open my designs from other Altium products?

CircuitStudio supports Altium Designer PCB Projects (*.PrjPcb) and will open any Altium Designer Schematic (*.SchDoc), so it can also be used as a front end for Altium Designer and other Altium products.

Note: CircuitStudio has its own PCB file format (*.CSPcbDoc). Use File>>Import to open CircuitMaker (.CMpcbdoc) and Altium Designer v5.0 (.PcbDoc) files.

The PCB file must be exported from Altium Designer as a specific binary version: In Altium Designer, with your PCB open. File > Save Copy As, set the Save as type: to PCB 5.0 Binary File (*.PcbDoc).
The 6.0 format is not yet supported in CircuitStudio, even though it is listed.

Is it possible to create a circular PCB in CircuitStudio?

It is possible to make circular PCB outlines, using SHIFT + SPACE to change corner mode while re-defining board shape.

Does CircuitStudio support embedding STEP models into the PCB design?

Yes, you can embed the .STEP file model into a new footprint and place it into the PCB design.

How can I view different angles of the board using the 3D PCB mode?

To move the board to any angle hold down the Shift key and click the Right mouse button and a rotational icon will appear. Keep holding the Shift Key and the Right mouse button while dragging the mouse to pan or rotate PCB to the desired view. The Shortcut keys 8, 9 and 0 can orient the 3D board view to predefined views.

Does CircuitStudio have keyboard shortcuts for features such as toggling via size or track width?

Min, Max, preferred via size is toggled with the 4 key or a favorite is set using SHIFT+V. Min, Max, preferred track width is toggled with the 3 key or a favorite is set using SHIFT+W. Press the Tilde key ~ while routing to see a list of available shortcut keys.

Is there a reference designator feature in CircuitStudio to automate or re-annotate from PCB?

There is no tool to automate a reference designator strategy. However, you can very much name the reference designators to whatever you like them to be on the PCB and push those changes back into the sch without the risk of losing the synchronization of the Sch and PCB. This is simply done by clicking on the update Schematics action while you are in the PCB mode. This will take you through the standard ECO dialogue boxes to execute and document the changes. Once you’ve done that, everything will match up.

How do you get the project to update the component footprint if the footprint in the library is changed?

Directly from the updated PCB library or from the project. If it is from the library just update the PCB by right-clicking on the item. If it’s from the project just push the updates after a compile to the PCB. This should change the footprint.

How do I highlight nets on my schematics?

The Underline Connections command (aka Highlighting Pen) can color the net within one sheet and can easily be navigated to other sheets to color them as well.

Tools > Underline Connections, left-click a wire and the wire highlights or "underlines" with a color.

  • Press SPACEBAR before clicking, then click another net to underline it with the next color. There are 7 fixed colors to choose from.
  • While using the command, hold Ctrl and left-click a Port to open the related schematic sheet and underline the same net with the same color.
  • To clear underlines for the entire project, click the bottom part of the Underline Connections button to Clear Underlines, or press Shift+Ctrl+C.

The Connection tool grays out my schematic. How do I clear the mask?

Home > Select, dropdown: Connection, click a net. This will mask everything except for the net.
To clear the mask in Schematic, either:

  • On the ribbon: View > Clear Masks
  • Press Shift+C

If you use Tools > Cross Probe and click a schematic component, the PCB will be masked except for that component. It can then be seen easily and selected, edited, etc., without affecting other objects.
To clear the mask in PCB, either:

  • On the ribbon: View > (Highlight & Edit Mask) > Clear
  • Press Shift+C
