Abstract: The use of more than one field-programmable gate array design with a given logic capacity produces advantages over the use of a single field-programmable gate array design. The designs of the field-programmable gate arrays in the family are be selected so that each field-programmable gate array design advantageously implements a different type of circuit. This use can select from the family of FPGAs with the same logic capacity such that the circuits can on average be implemented faster and/or in a smaller area.

First Claim:
Show all 38 claims
What is claimed is:     1. A method of implementing a digital circuit on a field-programmable gate array comprising the steps of:
  • providing a series of field-programmable gate arrays of different designs, at least two of the designs having the same logic capacity, and the designs having sufficient logic capacity to implement the digital circuit wherein the designs are devised such that each design can advantageously implement a subset of all circuit types;
  • determining the logic synthesis of the digital circuit into each of the field-programmable gate array designs;
  • determining the subsequent placement and routing of the digital circuit into the different designs to select a preferred design of the field-programmable gate arrays for the digital circuit; and
  • implementing the digital circuit on a field-programmable gate array of the preferred design.
