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.
The first approach ultimately resulted in SystemVerilog and extensions to VHDL while the second resulted in SystemC, all of which became Institute of Electrical and Electronics Engineers (IEEE) standards for the semiconductor industry.
