High Level Synthesis
In an attempt to reduce the complexity of designing in HDLs, which have been compared to the equivalent of assembly languages, there are moves to raise the abstraction level of the design, a sub-field called high-level synthesis. Companies such as Cadence, Synopsys and Agility Design Solutions are promoting SystemC as a way to combine high level languages with concurrency models to allow faster design cycles for FPGAs than is possible using traditional HDLs. Approaches based on standard C or C++ (with libraries or other extensions allowing parallel programming) are found in the Catapult C tools from Mentor Graphics, the Impulse C tools from Impulse Accelerated Technologies, and the free and open-source ROCCC 2.0 tools from Jacquard Computing Inc. Annapolis Micro Systems, Inc.'s CoreFire Design Suite and National Instruments LabVIEW FPGA provide a graphical dataflow approach to high-level design entry and languages such as SystemVerilog, SystemVHDL, and Handel-C seek to accomplish the same goal, but are aimed at making existing hardware engineers more productive versus making FPGAs more accessible to existing software engineers. It is also possible to design hardware modules using MATLAB and Simulink using tool HDL Coder from Mathworks or Xilinx System Generator XSG from Xilinx (formerly Accel DSP).

Famous quotes containing the words high, level and/or synthesis:
“Go on, high ship, since now, upon the shore,
The snake has left its skin upon the floor.
Key West sank downward under massive clouds
And silvers and greens spread over the sea. The moon
Is at the mast-head and the past is dead.”
—Wallace Stevens (1879–1955)
“To punish drug takers is like a drunk striking the bleary face it sees in the mirror. Drugs will not be brought under control until society itself changes, enabling men to use them as primitive man did: welcoming the visions they provided not as fantasies, but as intimations of a different, and important, level of reality.”
—Brian Inglis (b. 1916)
“The invention of photography provided a radically new picture-making process—a process based not on synthesis but on selection. The difference was a basic one. Paintings were made—constructed from a storehouse of traditional schemes and skills and attitudes—but photographs, as the man on the street put, were taken.”
—Jean Szarkowski (b. 1925)
