Featured Article | Mike Donnelly | 1 March 2018

Ever since the CAN specification was released many decades ago, designers have pushed their network configurations beyond the conservative limits of the standard, driven by manufacturablity, customization flexibility and other non-technical reasons. With thorough engineering analysis, including electrical simulation of the physical layer, they were able to design communication systems that meet both demanding performance and economic requirements.
