Cursor Snap Tricks in Schematic and PCB

Cursor Snap Tricks in Schematic and PCB

Last updated:

27/03/2012

Any experienced designer will tell you that grids and mouse cursor "snap" are important - even critical - to efficient design. After all, imagine a schematic tool not being able to recognize the connection of a wire to a pin because it was a pixel or two out of alignment?

But Altium Designer goes way beyond the traditional simplistic grid based systems most EDA tools possess. With the ability to work in a true dual-coordinate (metric AND imperial) system, with electrical snap grids, as well as multiple user-defined Cartesian and Polar grids and work guides - every possible scenario from placing parts to obscure copper shapes will be made exact and easy.

Announcement: Update 17 for Altium Designer 10

The Altium Development team are pleased to announce the 17th update for Altium Designer 10.

This release focuses on additional enhancements to Altium Designer, with some of the notable inclusions being:

Via Stitching:

Of particular importance for RF and High Speed designs, the brand new Via Stitching feature applies a definable pattern of vias between layers where the copper areas overlap and share the same net.  It helps maintain low impedance connections and short return loops through the board structure for developing high-performance, electromagnetically 'quiet' PCBs.

Via Stitching runs as a post-process using an algorithm that identifies all Fills, Polygons and Power Planes attached to a specified net, then populates free areas of copper with stitching vias to connect the layers using the specified via and stitching pattern. See the Wiki page for more information or watch the video on this new feature.

Improvements to Ansoft Exporter:

In update 16 we released improvements to this exporter to make it easier to import and simulate in Ansoft products. With this latest update, we’ve continued development and reduced the number of errors generated once imported into Ansoft (object centreline connection issues, and reducing differences between metric and imperial exports). Also, a larger array of component values are now imported, making it easier to set up the board for simulation.

Improvements to software update patching system:

The Altium Designer software patching system has been further enhanced to make the software update process less disruptive. Amongst a range of improvements, the patch preparation process has been configured to run during the update download at a low background priority, allowing Altium Designer to continue being used with minimal interruption. The update process now also provides the option to select whether you want to update using patches or a full download. This improvement will help those users who experience a lengthy update process due to anti-virus programs, where using the full download becomes a much faster process. Note: These improvements will only be visible with the next update to Altium Designer.

Schematic text overlay rendering

The BugCrunch request “Junction” over the “Text Frame” received strong support and achieved the full quota of 50 votes. So with this release, text container frames placed on the Schematic have been improved to display and print as the uppermost level, regardless of any electrical drawing primitives that the frame overlays. Another successful BugCrunch report - thank you to those who reported, nominated and voted!

In total, 5 BugCrunch items have been included in this latest update along with various other enhancements. Full details can be found in the release notes.

Accessing the Update

To update your Altium Designer 10 installation, first ensure you are using a license with valid subscription. Then, go to the Plug-in page (DXP >> Plug-ins and Updates) and select “Update All”. If you don’t see the update, use the “Refresh” link in the top right hand corner of the Plugins page.

The delivery of this update affects the following 8 modules:

  1. System Component category: Altium Designer Base, Altium Designer Installation System, PCB System, Schematic System
  2. Importers and Exporters: Exporter - Ansoft, Importer - PADS
  3. Output Generators: Output - Gerber, Printer - PCB

The download size of this update is approximately 10MB, assuming you have not recently cleared your cache. Installation of the updated modules will bring their revision up to 10.972.23595. The Platform Build number will also update to 10.972.23595 as the Altium Designer Base module is updated.

Note: If you are using a Private Server license or Standalone license and you have renewed your subscription since activation, you will be required to reactivate your license to obtain this and future updates.

The Supply Side: Counterfeit? But They Passed Testing!

Editor's Note: This article oiginally appeared in the February 2012 issue of SMT Magazine.

Substandard and counterfeit electronic parts have flooded the market during the past decade, sparking a national movement from industry players and market experts to address an effective solution. Although a few industry groups have implemented best practice anti-counterfeit procedures (IDEA-1010 and CCAP-101) and defined what classifies under the “counterfeit” umbrella, it is the United States government that is subsequently applying intense pressure to get the growing problem under control.

This past November, the Senate Armed Services Committee completed an investigation into occurrences of counterfeit electronic parts in the military supply chain. Lead by Chairman, Senator Levin and Ranking Member, Senator McCain, the committee held their first hearing to explore the shocking results and question industry experts. On the surface, it seems major changes are finally underway. Congress has since approved the National Defense Authorization Act for Fiscal Year 2012, which includes requirements to define the term counterfeit and establish a standard for the detection and avoidance of counterfeit parts. The standard will be issued by SAE, similar to AS5553 already in existence for electronic manufacturers, but will pertain to distributors only. The new standard, AS6081, is still being developed by the G19 Committee and is expected to be released sometime in 2012. 

Last month, SAE released ARP6178, Fraudulent/Counterfeit Electronic Parts; Tool for Risk Assessment of Distributors. According to SAE’s website the scope of the standard is “for all organizations that procure electronic components from sources other than the original component manufacturer. It is especially applicable for assessing distributors that sell electronic components without contractual authorization from the original component manufacturer.” 

With all the awareness and large improvements in counterfeit avoidance practices, why are so many companies still getting burned with substandard or bogus components? My quick and easy answer is they aren’t being thorough enough in terms of strict sampling and supplier evaluations. But, as we all know, there is nothing quick or easy about stopping the wave of counterfeits entering the supply chain. In the meantime, more and more OEM and EMS providers are running super lean, keeping long-term forecasting at bay and still supporting legacy builds. Critical shortages that require non-franchised solutions are consistently abundant, opening up a slew of quality issues for those that are sourcing from bush-league suppliers who do not care or do not know how to navigate an ever-graying market of trouble.

With so many layers of mitigation that can be applied to ones checklist, I suspect most companies get lost on what inspection and test efforts should be focused. For instance, we see a large number of companies strictly performing a basic parametric electrical test while de-capping one or two samples out of the lot to verify die authenticity. Although there is value in these procedures, they simply are not 100% effective in the determination of a component’s integrity.
