![]() The number of steps involved to just export a set of Gerber files leaves us craving a CAM file feature like in Autodesk Eagle. This comes at a price though, for both the user and PCB fab houses, particularly when it comes to exporting Gerber files for manufacture. It’s probably for this reason why OrCad/Allegro is still very popular and is often the software of choice for schools and businesses. On the other hand, despite the steep learning curve, those weaned on the software find the level of customization and detail appealing, and develop a better overall understanding into what makes a printed circuit board and, more importantly, how this is communicated in the production files. Those used to more beginner-friendly and self-explanatory programs such as KiCad and Eagle may be driven crazy by OrCad/Allegro’s counter-intuitive design flow and excessive right-clicking (me included). The software takes a bottom-up approach using various tools to make individual parts from pads to the final PCB layout. ![]() Cadence Allegro and OrCad are the oddballs of the PCB EDA software giants. ![]()
