The design of each of these electronic devices generally proceeds from a high- to a low-level of abstraction. For FPGAs the low-level description consists of a binary file to be flashed into the gate array, while for an integrated circuit the low-level description consists of a layout file which

Each design step requires specialized tools, and many of these tools can be used for designing multiple types of electronic circuits. For example, a program for high-level digital synthesis can usually be used both for IC digital design as well as for programming an FPGA. Similarly, a tool for
