UNISIM Virtual Platforms

UNISIM Virtex 5 FXT Simulator
A full system simulator of a Xilinx ML507 development board based on a Xilinx Virtex-5 FXT chip. The simulator simulates the embedded processor block (PPC440x5 + Crossbar + MCI + DCR Bus Controller) and some Xilinx Platform Studio IPs (XPS IntC, XPS Timer/Counter, XPS UART Lite, XPS GPIO). The simulator can emulate a terminal console over the UART Lite (UART Lite I/Os are redirected to an external telnet client over TCP/IP). The simulator can also boot Linux for Xilinx Virtex-5 FXT.
All releases:
UNISIM ppcemu Simulator
A user level PowerPC simulator with support of ELF32 binaries and Linux system call translation. This simulator can run simple PowerPC Linux applications.
All releases:
UNISIM ppcemu-system Simulator
A full system simulator of a "PowerMac G4 PCI" like machine (MPC7447A/MPC107) with Linux boot support.
All releases:
UNISIM embedded-ppc-g4-board Simulator
A full system simulator of an MPC7447A/MPC107 board with support of ELF32 binaries and targeted for industrial applications. The simulator can be driven and stimulated by an external program (over TCP/IP) through a fake peripheral (PCI stub) on the simulated PCI bus.
All releases:
UNISIM ARMemu Simulator
A user level ARMv5te simulator with support of ELF32 binaries and Linux system call translation. This simulator can run simple ARMv5te Linux applications.
All releases:
UNISIM AVR32emu Simulator
A user level AVR32A simulator with support of ELF32 binaries and AVR32 Newlib target-to-host system call translation.
All releases:

UNISIM TMS320C3X Simulator
A TMS320C3X DSP simulator with support of TI COFF binaries, and TI C I/O (RTS run-time).
All releases:


A tool to generate the C++ source of an instruction set simulator from a description of an instruction set architecture (.isa files).
All releases:


Cross tool-chains
GNU Cross tool-chains
Some cross tool-chains to compile C/C++ programs for the PowerPC G4, PPC440, ARM926EJ-S and AVR32 targets, e.g. for the UNISIM ppcemu, UNISIM ppcemu-system, UNISIM ARMEmu and UNISIM AVR32emu simulators. These are extensively based on Crosstool-NG.
All releases:
cross-GDB for C3x/C4x

Virtual Platforms



We would like to thank Digiteo that supported us in making the UNISIM virtual platforms available to the community.


We presented a poster at the poster sessions of the HiPEAC'12 conference, January 23-25, 2012, Paris, France. The HiPEAC conference provides a forum for experts in computer architecture, programming models, compilers, and operating systems for embedded and general-purpose systems. The conference aims at the dissemination of advanced scientific knowledge and the promotion of international contacts among scientists from academia and industry.

On-going evaluation

A UNISIM virtual platform of a Xilinx Virtex-5 FXT is being evaluated by project partners in the context of OPEES (Open Platform for the Engineering of Embedded Systems), a European project that aims to ensure long-term availability of critical / embedded systems engineering technologies to secure industry competitiveness and development.
