Signs is a development environment for hardware designs in various hardware description languages. The tackled tasks are compilation, synthesis, simulation, and testing of designs. Due to the integration of these main areas, it provides the ability to debug designs in an all-embracing manner by switching between source code, netlist, and simulation. Supported languages include VHDL and the ISCAS benchmark format. Signs comes in two flavors: a command-line only version useful for processing and analyzing large netlists and as an Eclipse plugin for hardware design and simulation.
