FORMATION OF COLUMNAR APPLICATION SPECIFIC CIRCUTRY USING A COLUMNAR PROGRAMMABLE DEVICE

A columnar programmable device (PD) design converted to a columnar application specific integrated circuit-like (ASIC-like) design is described. A user design is instantiated in a PD having a columnar architecture associated with the columnar PD design. The columnar architecture has adjacent columns of circuitry, and one or more of the columns of circuitry as associated with instantiation of the user design in the PD are identified. At least a portion of one or more of the identified columns are swapped with application specific circuitry for implementing all or part of the user design for converting the columnar PD design to the columnar ASIC-like design.
