Used to ensure you don’t place components on top of each without getting a DRC. This boundary normally defines the component area which may or may not include pins of surface mount devices. This boundary can also be assigned a component high to be verified at the board level and checked ...

Show all destination pins highlights all valid destination pins across all connectors that can accept the signal(s). Show all destination pins on component highlights all valid destination pins that can accept the signal but only within the same component. This algorithm is the only mode that was...
to the Package_Keepout_Top boundaries or any other special component clearances. If this boundary does not exist than it will be automatically created based on the Assembly_Top outline and the outer extents of the component pins. This boundary can only be defined at the symbol level (.dra)....

In this way, you only have to constrain the single Bus object once rather than having to repeat this process for each signal. Through inheritance, each signal in the Bus receives the constraint value assigned at the Bus level. In certain worksheets in the Electrical domain, the children of ...
Allegro PCB Editor stores design data as various types of objects in a proprietary database format. These object types can create a complete representation of an electronic circuit. You can create, operate on, and extract information from the databas...
