                You can design ANY board in Altium Designer. For advanced boards (e.g high speed designs) the PCB layout process may take a little bit longer as it would take when an another advanced tool such Cadence Allegro is used (a few days or weeks more), BUT you will save time on other things – such component management. Also, <a href="http://live.altium.com/#software" >Altium Designer costs $5000</a> what is much less then Cadence Allegro which, as I know, starts somewhere around $25000 plus fees for every year. (Just for information full PADS price is around $15000, a cheaper tool like EAGLE costs around $1500)</span></li>
            <li class="content-list-item"><span class="content-text"><b>Great Component Management</b><br>
                By using Variants in Altium Designer you will save a LOT of time. A board has many times more then just one variant – board with different memory sizes, different range of input voltages, different resistor settings, … Just generating all the manufacturing information for all this variants takes a lot of time (BOMs for purchasing, BOMs for manufacturing, Assembly drawings, Schematics, …) and then … a hardware change needs to be done and re-generate all the information again … and again. In Altium Designer, once everything is set up correctly, it takes only few clicks.

            <li class="content-list-item"><span class="content-text"><b>Excellent Schematic Browser</b><br>
                You always want to be sure the schematic is correct. No one wants to have swapped receive and transmit signals, two outputs / inputs connected opposite of each other, using wrong power rail, forget pull up / down resistors, …. Altium Designer provides an excellent schematic browser what allows you easily check connection for EVERY pin in your schematic. It’s my favourite feature. See <a href="https://fedevel.com/blog/2011/03/best-way-to-check-orcad-schematic-use-altium-designer/" >comparison between Orcad and Altium Designer Schematic browsing here</a>.</span></li>
            <li class="content-list-item"><span class="content-text"><b>3D visualisation and output</b><br>
                The 3D feature of Altium Designer is SO SIMPLE TO USE. Clients love 3D outputs. They can see the product weeks or months before it’s physically on their table. I use the visualisation to check component placement and it’s especially useful when board is being designed for a bigger system. See <a href="https://fedevel.com/blog/altium-designer-3d-model-and-real-pcb-side-by-side/" >3D model and real PCB side by side here</a> or <a href="https://fedevel.com/blog/altium-designer-3d-model-of-your-pcb-its-reallyeasy/" >learn how to create 3D models here</a>.</span></li>
            <li class="content-list-item"><span class="content-text"><b>Support</b><br>
                It’s a very well known software used by wide community. The Altium Designer Help pages are good written and save a lot of time. Usually it takes no longer then 5 minutes to find and use a new feature.</span></li>

        Altium Designer is All in One solution and if you are in process of selecting new software for your Hardware Design team, then consider Altium Designer as one of your options.<br><br>
