Icarus Verilog is intended to compile ALL of the Verilog HDL as described in the IEEE-1364 standard. Of course, it's not quite there yet. It does currently handle a mix of structural and behavioral constructs. Icarus Verilog is not aimed at being a simulator in the traditional sense, but a compiler that generates code employed by back-end tools.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
