Allegro X System Capture (EE Cockpit) - Recent Threads

RE: Understanding the Role of config.xml in Power Topology Analysis

EM202610218420 — Thu, 22 Oct 2026 06:33:24 GMT

When troubleshooting display issues while using tools like Allegro X System Capture, it’s worth checking that your graphics driver and monitor are configured correctly. If you’re having trouble with available resolutions, the Custom Resolution Utility guide may help you explore supported display modes. Just make sure any custom resolution is compatible with your monitor and graphics driver.

Understanding the Role of config.xml in Power Topology Analysis

WallEE — Tue, 22 Sep 2026 13:03:38 GMT

In the previous article, we explored how Power Topology Analysis in Allegro X System Capture helps visualize and validate power distribution networks (PDNs) directly from schematic data.

As designs grow in complexity and organizations adopt customized libraries, enabling accurate device identification becomes increasingly important. This is where the config.xml file comes into play.

What is config.xml?

The config.xml file is used by Design Integrity analyses to define how devices, pins, and properties are interpreted during analysis. It acts as a central configuration mechanism that allows the analysis engine to understand and work with company-specific library conventions.

Although Power Topology Analysis can automatically identify many common devices, every organization structures its libraries differently. Custom ref des for symbols, pin property names, and device definitions can make automatic identification more challenging. The config.xml file provides the flexibility needed to align the analysis with your library standards.

This configuration file, written in an XML format, manages various aspects of a device configuration used in the design integrity flows within System Capture. Under Cadence installation, the config.xml file contains the default values of all the parameters used in the design integrity flows. The file is available at the following location: SITE\cdssetup\sysr\config.xml

Note: Always keep a backup of the file and do not edit the original file. To edit or understand the contents of the config.xml file you can connect with ASK team at Cadence.

Why is config.xml Important for Power Topology Analysis?

Power Topology Analysis relies on correctly identifying power-related elements in the design, including:

DC Sources
DC-DC Converters and LDOs
Pass-Through Devices
Power Sinks
Power Nets and Voltage Rails

Accurate device classification is essential for constructing a meaningful representation of power flow(Power Tree) throughout the design.

By using config.xml, organizations can customize how Power Topology Analysis recognizes these devices and interprets library information.

Example

Consider a design that uses internally developed libraries containing custom refdes for device or different pin naming conventions.

Without additional configuration, some components may require manual identification before analysis can accurately build the power topology.

By updating the config.xml file to reflect company-specific library conventions, device recognition can become more consistent across projects, reducing setup effort and improving analysis accuracy.

Benefits of Using config.xml

A well-configured config.xml can help:

Improve automatic device identification
Reduce manual topology setup effort
Reuse existing library information
Support company-specific library standards
Improve consistency across projects and teams
Enable more accurate topology generation

For organizations managing extensive schematic libraries, these benefits can significantly simplify the adoption and deployment of Power Topology Analysis.

When Should You Consider Updating config.xml?

You may want to review and customize the configuration when:

Devices are not identified as expected
Libraries use custom properties or naming conventions
Additional identification rules are required
Analysis setup requires frequent manual adjustments

Finally, understanding how config.xml influences Power Topology Analysis is an important step toward getting the most value from your existing libraries and design data.

RE: SysCap - Tip of the Week: Reordering blocks

JK202608104547 — Tue, 13 Oct 2026 11:37:20 GMT

I play here most evenings and want to share why this crypto casino suits me so well. What I enjoy as a player is that everything sits on one screen, so I never waste time switching around. This Pakistani platform loads fast and bonuses appear without any code hunting. Playing here is relaxing and I always stop once my budget is done. Simple and genuinely enjoyable.

SysCap - Tip of the Week: Reordering blocks

DesignTech — Fri, 24 Jun 2022 07:03:05 GMT

In hierarchical designs where the same block is instantiated multiple times, it is often desired to rearrange the hierarchical blocks in a specific order.

System Capture allows you to reorder blocks so that they are displayed, published, or printed in the desired order.

Modify the project or site cpm file with the following directive to enable this feature.

START_CANVAS

module_ordering 'true'

END_CANVAS

Drag and drop the block to the required position in Project Explorer to reorder the block.

Efficiently Replace Components, Nets, and Properties in Allegro X System Capture

Akshay khosla — Wed, 07 Oct 2026 12:32:01 GMT

Design changes are a normal part of schematic development, whether driven by evolving requirements, component availability, or ECOs.

Allegro X System Capture simplifies these updates with the Find and Replace feature (Edit → Find and Replace). By selecting Advanced, you can define the scope of changes as Entire Design, Block/Page, or Selection.

With a few clicks, you can:

Replace components throughout a project
Rename net names globally
Update properties in bulk

This capability helps reduce manual effort, improves design consistency, and accelerates design updates across large projects.

Have you used Find and Replace to streamline schematic changes? Share your experience with the community.

Controlling Accessibility of Components when place component in schema

MZ20250602835 — Thu, 01 Oct 2026 07:11:08 GMT

Dear All,

in DE HDL, i can restrict the availability of some components with using The Search_Result_Highlight_Attr_Name directive in the project .cpm file to specify the attribute name for highlighting search results in the Component Browser, to define which attribute's values will trigger specific actions, such as highlighting or generating warnings/errors for components based on their status. For example, disable the addition of these physical parts which have the status "in active"; Or give a warning if try to add a not preferred part in design.

may i ask if it is possible to use/define color within unified search similar as DEHDL?

comp_browser/comp_browser17.4-2019/2_configure_comp_browser.html#pgfId-1052684

How can I highlight two attribute values in Component Browser from a single attribute name in project .cpm file?

Best Regards

Moyan

RE: Controlling Accessibility of Components when place component in schema

rg13 — Thu, 01 Oct 2026 07:35:40 GMT

Yes, this solution used to work in DEHDL.

However, for standalone System Capture, you can develop TCL script which can show kind of warning/error based on status of the part from Unified search part row.

If System Capture client is connected to Pulse server through PULSE_REMOTE_URL then Lifecycle status can be configured in search.config for such requirement. You can refer below:

thanks. Will try this. We do get impacted by duplicated schematics at times

RE: Join our next Live Ask Me Anything Session on System Capture on September 23, 2026

AyushD — Wed, 23 Sep 2026 16:03:07 GMT

when you are working on a shared design, whenever you open any project from pulse you acquire a lock on that design and other users with whom the design is shared they will see a lock icon on the design as it is being worked upon by another user and once 1st user is done with the changes and commits the design, the lock will be removed for other user to modify the design.

Similarly if it is page level sharing, users will see the lock on particular page that is being worked upon by other user.

If you commit your changes to the design efficiently it should avoid any conflicts.

Hi,

In Allegro X System Capture, the preferred workflow for managing hierarchical blocks when underlying schematics vary slightly across product variants relies on Variant Management. This avoids maintaining separate, duplicate schematics and preserves the integrity of design reuse.
