Welcome to the home page for IVIonOSX. This is the source for a GPL'ed VHDL and Verilog simulator and waveform viewer, shrink-wrapped as a ready-to-use installer for MacOSX.
The goal of the IVIonOSX effort is to port the required tools to the Mac and maintain a reliable binary distribution that is as Mac-like as possible.
IVIonOSX currently integrates the following tools which
are described in more detail below:

IVIonOSX requires Apple's free Developer Tools to be installed.
The latest Developer Tools may be downloaded via the Apple Developer Connection:
IVIonOSX embeds the Tcl/Tk Aqua frameworks. For further

IVI is a GPL'ed simulator frontend, to perform interactive VHDL and Verilog simulations, and waveform viewing.
IVI allows to integrate a variety of simulator engines, currently adaptions for GHDL, Icarus, and Cver exist.

Icarus Verilog is a GPL'ed Verilog simulation tool. It is intended to parse and elaborate design descriptions written to the IEEE standard 1364-2001. Icarus Verilog has been used successfully to simulate the OpenRisc1200 processor.
Icarus operates as a compiler, compiling source code written in Verilog into a pcode format, which may be executed by a simulator kernel.

GHDL is a GPL'ed VHDL simulator, based on GCC technology. GHDL implements the VHDL language according to the IEEE 1076-1987 or IEEE 1076-1993 standard. Nearly all VHDL87 (common name for IEEE 1076-1987) standard and most features of VHDL93 (aka IEEE 1076-1993) are supported. GHDL has been used successfully to simulate the DLX and Leon processors.
GHDL compiles VHDL code directly into executable binaries, which may be executed in the shell.
