Which Software Is Best For PCB Designing, PADS Vs Altium Designer

Mentor’s PADS Professional is an advanced and capable PCB design application, with features such as SIA, thermal analysis, AMS Cloud circuit online simulation and more such. In short, it has all the features you might require for making any sort of advanced or complex design.

But when it comes to the core of designing, making your layouts and schematics, users prefer the ease and personalisation features Altium provides. Altium’s simulation properties are not as optimised as PADS’. So depending on the tasks, both programs have their advantages and disadvantages.

PADS Professional Vs Altium Designer: Who’s the Winner?

Both Altium and Mentor are experienced companies and have been making design products for a while now. Even so, when it comes to PCB designing and all factors considered, PADS feels a little out-dated and is not very intuitive.

The work-flow and navigation can be still improved and the overall user-experience for designing is not up to the mark considering the cost of the license for PADS.

Meanwhile, the Altium experience was certainly a bit better. The integration and custom options make the task of a designer much easier. There are limitations and still a lot can be improved in Altium as well, but on the whole it performs a little better.

So, Which One Should You Pick?

Which one you should pick between Altium Designer vs PADS Professional is a matter of personal preference.

There is no overall winner, but as stated earlier, the design experience is smooth and optimised while using Altium. PADS still has powerful simulation and analysis features that work really well, and are state-of-the-art.

Mentor has provided ample features to justify the price of PADS Professional, and it also comes with translator libraries to help users who might want to migrate from some other EDA (Electronic Design Automation) platform.

Both of these software are in the higher pricing range and are not small investments, so it is recommended to take their trial versions before purchasing the license.

Hopefully, you have found this PADS v Altium Designer comparison guide worthwhile and it has helped you to make an informed choice about these two PCB Design Software.

  1. Hello,

    the pricing you are referring to for the Altium Designer license is a pricing model with a perpetual license. There are also TB licenses for cheaper pricing and a new model called Altiflex.
    The biggest benefit of Altium Designer is that it is a unified product for all disciplines without modules to pay for extra and you will get with your subcription a top level support and newest version for free.
    Altium is the only company which offers within the subscription a cloud based plattform A365 for free on which you can collaborate and work on designs with all involved companies and people globally who use AD also.

  2. Altium was shown to me in 2014 and I wouldn’t want it even for free. I often need to make precisely defined motifs, and the program could not do that. Learning by study of documentation, according to representatives, was unthinkable. Only real study was payed training and support. I am long user of PADS Standard, which is not a superior tool but it can do almost anything needed also in complex boards. Now I am planning upgrade to Professional edition. I think that Altium could be appropriate for consumer electronic products but not for industry products with advanced quality management. Is only my impression gained on basis of described features and functionalities.

  3. Having used both Altium and PADS Pro for years I can tell you without a second thought that PADS Pro is the one I would pick. I question some of the statements mentioned in the writeup. The one that sticks out is PADS Pro is not suited for multiple engineers and designers designing remotely. That statement is just not true. PADS Pro uses the Xpedition core engine. Which means using a corporate library which can be on a server in Tim Buck Two. Your EE’s can be working on the schematic live (several at once mind you) in Canada while the PCB layout specialist is working from home routing the board. Oh did I mention the real time sharing of information with the ME group in 3D using STEP models. The routing tools in Altium while good can not even hope to compare with PADS Pro due to the way the rules are set up. In PADS Pro you use a tool called CES to set constraints such as Diff pair routing, Net Class to net class spacing requirements, and on and on. You can have a VERY large rule set and the tool hardly slows at all. (32 gigs of RAM is recommended) In Altium the larger the rule set the slower the design. An example of this is real time plowing of a trace thru a plane. In Pro the trace rips right thru while following every rule in real time. With Altium I have waited 3 or 4 minutes for the tool to process the command. Oh there are “tricks” that you can do in Altium for it not to do this. The trick in to not have real time DRC on!! Which means you run DRC later and clean up your errors that you made in order to not wait for the tool to process and follow the rule set in real time.

  4. My company maintains multiple perpetual licenses of both PADS Standard Plus and Altium Designer. Both are extremely powerful tools, and both are capable of making any of the circuit board designs that we have needed. However, PADS is far slower to use and more prone making mistakes in (mainly due to the excessively configurable Gerber generation process). The interface and basic flow for using PADS hasn’t changed much since 1995, and its capabilities have only been expanded marginally, despite what the marketing department says. It feels like PADS is only being limped along by Siemens. On the flip side, Altium has a history of changing too much from version to version, adding new features without ensuring the last round of new features is bug free. This has been less of a problem in the last few years, but was especially bad from 2005 to 2015. Some of those problems persist today. Altium is definitely a more modern tool, with more ways to collaborate and share, easier and faster ways to integrate with other design tools, and more ways to manage BoMs than any one person can ever learn. In summary, both tools have upsides and downsides, but I prefer Altium as the better tool.
    Circuitmaker is a free online CAD tool that is based on Altium. For a time, Digikey sold a cheaper version of PADS Layout and PADS Logic for enthusiast use.

  5. PADS standard is what I use and it is obviously being deprecated by Siemens in favor of PADS Professional.
    Sieman is currently offering a free upgrade from Standard to Professional which is much more capable and future proof but will require learning a new toolset. Optional modules ($$) available with the PADS professional version give it very advanced capabilities that Altium to my knowledge does not offer.
