Abstract: A method of implementing a circuit design in a circuit design tool for configuration in a programmable integrated circuit (IC) connected to components on a circuit board is described. The method includes processing a first file associated with the circuit board to obtain descriptions of circuit board interfaces of the components on the circuit board; displaying a graphic user interface (GUI) of the circuit design tool to connect a circuit board interface described in the first file with a circuit design interface in the circuit design; generating physical constraints on the circuit design interface with respect to input/outputs of the programmable IC described as being connected to the selected circuit board interface; and generating a bitstream to configure the programmable IC. The bitstream includes a physical implementation of the circuit design satisfying the physical constraints.

Abstract: An exemplary method of implementing a circuit design for a programmable integrated circuit (IC) includes, on at least one programmed processor, performing operations including: generating a description of circuit components of the circuit design including first portion of a circuit module that is independent of assignment of resources of the programmable IC; assigning a plurality of the resources of the programmable IC to a plurality of the circuit components including determining at least one resource assignment for the circuit module; and generating a physical implementation of the circuit components for implementation in the programmable IC, including generating a second portion of the circuit module that is dependent on the at least one resource assignment, and combining the second portion of the circuit module with the first portion of the circuit module.

Abstract: A method is provided for exporting design constraints from a circuit design. In response to a first user command indicating a design constraint and a pattern, the design constraint is assigned to each object in the circuit design that matches the pattern, and the pattern is stored in a database. In response to a second user command to export design constraints of the circuit design, for each design constraint assigned to a respective set of objects of the circuit design, a pattern stored in the database that matches the respective set of the objects is determined and the design constraint is added to an export file in a format that uses the determined pattern. Design constraints on individual ones of the set of the objects indicated by the determined pattern are omitted from the export file.
