PCB Schematic Design with DxDesigner

All about PCB design creation using the most widely adopted Mentor Graphics product, DxDesigner.

22 July, 2014

The weather has been warm in Colorado this week, so that means the windows and doors are now off the jeep. When I’m enjoying the open air I prefer to go on the less used roads, even if my journey is longer. This means I have to turn off the automatic mindless driving mode and think about the journey.  For example, I don’t automatically turn left to get on the main road, I want to go forward and enjoy the new route.

At Mentor Graphics we have been working on several new routes. Our developments with the VX xDX Designer have now been released in the PADS flow with the same core features that will be released in the Xpedition flow later this year.  If you missed a live PCB forum you can watch our webinar at http://www.mentor.com/pcb/multimedia/highly-productive-design-creation-with-xdx-designer

We are also beta testing with our new partner Digi-Key a new web assisted schematic entry tool (coming soon a layout tool).  Designer Schematic simplifies the schematic entry and library process with web enabled downloads of fully annotated part symbols using PartQuest.  PartQuest finds information from suppliers like Digi-Key and adds PCB and schematic ready symbols to download to your local computer fully annotated part information simplifying and reducing errors in schematic entry and speeding the manufacturing of the PCB design.designerstartup

Do you use PADS?  Did you know that the PADS ES Suite ships with the DxDesigner Schematic Editor providing a robust and powerful design environment tightly coupled to PADS layout with DxDatabook a powerful component information system and cross probing.


With an innovative and reliable architecture, designed from the start to support hierarchy; a user needs only to create a circuit once before reusing it many times in the same design. Or use hierarchy to logically partition your design into clear and concise functional blocks.

Included with PADS is an efficient and powerful component information system. Connect to popular databases and quickly search and find up-to-date parts and information to add to your design. Are you almost finished with the design but need to add more information to all of your components, integrated utilities will both verify and update your design quickly and accurately in minutes ensuring the schematic and PCB are up to date and current.

Crossprobe from the PCB to the schematic or from the schematic to the PCB to quickly find specific parts or nets in your design for critical placement and routing. Select groups of parts in the schematic and with the power of cross probing those same parts will be selected in the PCB for critical placement and efficient net routing.

Unlike other tools, PADS features tight integration between schematic and layout with seamless forward and back annotation keeping your design in sync. Swap pins and gates on the PCB and stay in sync with the schematic, renumber your circuit board to clearly find parts and back annotate the new reference designators to the schematic. Add or remove parts to the schematic, or rename nets for clarity and find these changes replicated correctly in the PCB.

Explore PADS yourself with our new PADS Virtual Lab, or our free trial and evaluation guide supplied with the PADS ES suite download.  The evaluation guide walks you through a design to introduce you to the Power and integration found in PADS, by Mentor Graphics.

So far 2013 has been a great year to explore the creative drawing aspects in DxDesigner.  I’ve been ignoring my blog writing but I’ve been drawing several new schematics and updating many of our older reference designs with the new capabilities in DxDesigner 7.9.4.

In the example below, an entire new design was created, from a new library symbol set, finding and drawing a reference schematic design, and finally the placing the components on the circuit board and routing the PCB. The photo below is one of the new samples, an actual design, captured using DxDesigner for PADS 9.5 with an associated PCB that forwards and back annotates from PADS to DxDesigner.  It’s not a boring schematic anymore :)

You may notice the color is “interesting” but the coloring of the schematic is entirely based on automatic colors, uniquely demonstrated with a new color scheme, and the layering capabilities now in DxDesigner backlighting the otherwise transparent integrated circuit symbols.  Although you may not want to work with a color scheme like this all the time, if you fondly remember the ammonia scent of a blueprint duplicator you may want to try something similar in your next PowerPoint presentation.  And if you need to add a circuit board, below is the design created from the above schematic.Download the DxDesigner color schemes I use at the Mentor Communities site.  http://communities.mentor.com/mgcx/docs/DOC-3523

A few weeks ago I was visiting a nearby customer to demonstrate the powerful ELDO SPICE simulator as an add-on to our HyperLynx Analog simulation lauchpad. To navigate through the schematic, I clicked on the arrows I use for links on the cover page to jump to the page for simulation. After the demo was complete the customer asked me, “You clicked on an arrow on the table of contents page and ended up on the page you wanted to simulate. How did you do that?” The answer is using a Link.

A Link is simply an symbol of type annotate, that is listed in the special components file of the project as a Link. Because it is a symbol, it could have any shape or design on your schematic. Connected Links don’t need to be the same symbol, they only need to share the same name. Links were introduced in DxDesigner for EE7.9.2 to assist in cross referencing your schematic pages. With the EE7.9.4 release, Links were enhanced to traverse through the design hierarchy simplifying navigation and your ability to verify connectivity in your design. The number of Link symbols I used in the Aspen design added up to 17 symbols and made the dropdown list quite long.

As we introduce future versions of DxDesigner we are looking to optimize the dropdown list, simplify Link settings, and improve the capabilities Links provide. If you have any suggestions in our Link capability, please create a post in the Mentor Idea’s site for DxDesigner! In the meantime, they work great and provide a quick method to jump though your schematic. If you want to see how I used Links in Aspen, check out the Virtual Lab!

Happy New Year!

Much of the your end PCB product costs can be directly influenced by the parts selected up front during the schematic capture phase of the design process. When you incorporate information into the designer’s part selection interface such as preferred part status, compliance, and/or obsolescence, you can reduce the work and rework of designs thus saving you additional costs.

Today, it is a challenge for designers to produce designs that are pushed by time-to market, compliance restrictions, and the constant need to reduce costs. Many times the designer does not have access to critical component information within their “field-of-vision” causing them to rely on other disciplines to constantly check their part selection after they’ve done all the “hard work” of designing.

I equate this to me finding furniture for my home, moving the furniture around to the perfect spot, and then my wife saying, “No, I don’t like the pattern on the sofa!” I’m thinking, why couldn’t you tell me what colors you like before I started? Better yet, why didn’t we agree on the sofa at the beginning? Why did I do all of that work fitting that sofa in the living room and now you tell me you don’t like it? Of course I would never say these things out loud! This is exactly how designs are being done today and we accept it because it’s considered to be the norm. We utilize disconnected third party tools to push non-standard data for validation by somebody else’s database … usually a bill-of-material. We fool ourselves into thinking this process is controlled because we do this during a design review after the room has been completed. Wrong! To me this is like getting my mother-in-law to look at pictures of my room and then telling me what my wife wants. Thanks but NO THANKS! In this scenario, I’m the designer, my wife is a component engineer, and the mother-in-law is my PLM. I don’t need the pain nor aggravation of dealing with multiple “sources” after I’ve already moved the furniture; all I want is accurate and upfront information.

What you need are tools that help you communicate without the overhead of complicated communication and without using transformations of data (pictures) during the work-in-process phase of the process. What do you need? A multi-phased approach as outlined below. Why not make it easy on your designers and have them focus on the heavy lifting? Why not be proactive instead of reactive? With DMS, we can provide the simple communication and drive behavior without complex interfaces or running back and forth between your mother-in-law. See how you can save time by taking a look at my webinar now on demand for more details on how DMS can provide this seamless solution for you.

* I do like my mother-in-law and the opinions in this blog are my own :-)

  • Integrated Library & Component Information - Provide the approved or preferred information within the designers interface to make it easier for them to choose and use (not another database).
  • Shopping List - Create list of preferred parts for specific sites or projects that designers can easily choose from.
  • Production Libraries - Create strong filters that can automatically remove non-standard or obsolete parts from designer’s view and actually highlight failures during design validation.
  • Compliance Audits - Allow any approved user to view the work-in-process status and run configurable compliance audits before the design is completed.

Short for Web-based seminar, a presentation, lecture, workshop or seminar that is transmitted over the Web.   This week the DxDesigner team completed a series of 4 webinars with the following titles:

If you happened to have missed any or all of the above webinars, they have been archived for viewing at your leisure.  Each of the above webinars was produced by the DxDesigner marketing team and contain demonstrations and highlights of the productivity features in DxDesigner.  There are even some next release easter eggs in the above presentations as we continue to improve DxDesigner as the industries premier PCB schematic capture program.

Other teams in Mentor have also produced great webinar content on designing PCB’s.  For example the Expedition team produced a series earlier this year to  Solve Today’s Toughest PCB Layout Challenges with Expedition Enterprise.  Our PADS team has produced many webinars that can be found at their home page  www.mentor.com/pads.  Our support group has also produced content posted on technote MG579949.  For the support webinar series you will need a supportnet account.

Learn more and become more efficient in your use of the Mentor Graphics PCB tool suite by watching a webinar today!

Did you know that support for documenting your designs with custom borders has been enhanced in recent releases of DxDesigner to automate and improve the ease of use and accuracy in documenting your electronic designs.  Several Parameterized Properties  reflect the current design information on your border symbol.  Properties like @NAME, @SHEET, and @PRINTORDER are used to display the information specified and are adjusted using the Navigator for each schematic page.  Do you need a date stamp on your schematic?  Use @DATETIME and adjust the format to your companies specifications in Setup> Settings> Display> Date Format.

Because fixed embedded properties shipped with DxDesigner may not always meet your needs, our schematic entry program is flexible for you to utilize your own properties.  I’ve typically defined these properties uniformly with the same prefix.  In this case the word Drawing is used as a prefix to all of the custom border properties in the design.  I simply added the properties to the Properties Definition Editor, assigned them to the border page and then they can be universally adjusted by selecting and editing the Border Properties in Setup> Settings> Borders and Zones.  Specifying the properties in one place ensures their accuracy thoughout the entire design.

Notice the hashed outline (and red selected outline) below the information panel in the graphic above.  This is known as the symbol outline.  Often times the information pane is on the lower right of the schematic, but many borders have a symbol outline and are only selectable in an extremely small area on the lower left of the schematic, far from the information that is needed to review.  Extending the symbol outline across the lower portion of the border allows the user to select and edit properties locally without panning across the canvas, significantly improving the ease and accuracy  of editing.

Do you need more information?  Ask the DxDesigner Experts or explore on you own with  Technote MG529885,the DxDesigner User Guide and Properties Glossary for more information on how to optimize your borders in DxDesigner.
