One of the key upgrades in 8.8 is the enhancement to the Design Rule Check (DRC) feature, which now supports - user-defined areas on the PCB where specific design rules apply. This is essential for mixed-technology boards where you need different clearances for different sections, such as escape routing for a BGA, fine clearances around high-density SMT pads, isolation spacing for high-voltage circuits, or controlled impedance for RF sections and edge connectors.
Proteus 8.8 is a major release of the Proteus Design Suite , a comprehensive software used for electronic circuit design, SPICE simulation , and professional PCB layout. The "Portable" version typically refers to a configuration that allows users to run the software from a USB drive or external storage without a standard installation on a host PC's registry.
