SpecC
SpecC is a System Description Language (SDL), or System-level Design Language (SLDL), and is an extension of the ANSI C programming language. It is used to aid the design and specification of digital embedded systems, providing improved productivity whilst retaining the ability to change a design at functional and specification level, unlike HDLs like Verilog and VHDL. An architectural model can be created which allows other tools to directly map the design onto silicon or FPGA. The main aim is for the reuse, exchange and integration of IP at various levels of abstraction.
