ABSTRACT:
An automated system for partitioning a set of Boolean logic equations onto one or more devices selected from a plurality of commercially available devices. The system utilizes a processor having a memory containing information on the different architectural types of devices, physical device information on individual devices and user generated design constraints, weighting factors and partitioning directives. Based upon this stored information, the system of the present invention selects all acceptable architectural types of devices wherein at least one of the Boolean logic equations can be placed thereon. For all physical devices associated with the acceptable architectural types only those devices which fall within the selected user constraints are selected. The system then evaluates the weighting factors to order the devices in order of cost value and then fits the equations according to the partitioning directives to the devices. During the fitting process, an optimum device solution is attained having a least cost value for which the system produces an output map suitable for the user of the system to configure the selected devices to implement the set of equations.
