<h4><span style="font-family: helvetica,arial,sans-serif;">Reference
architecture</span></h4>
<small><span style="font-family: helvetica,arial,sans-serif;">The
LEON3MP is made up by cores from the GRLIB IP library, which are
connected together via the AMBA AHB and APB buses. The plug&amp;play
configuration method of GRLIB makes it possible to assign any
combination of addresses and interrupts to the cores. However, to be
software compatible with simple operating systems such as the LEON
Bare-C cross-compiler, some of the vital cores must be assigned to
predefined addresses and interrupts. The table below shows the
reference assigment in the LEON3MP design:<br>

<h4><span style="font-family: helvetica,arial,sans-serif;">Configuration</span></h4>
<div style="text-align: left;"><small><span style="font-family: helvetica,arial,sans-serif;">The configuartion of
the LEON3MP design is defined through the config package located <a href="config.vhd">config.vhd</a>.
This file can be automatically generated using a GUI based on tkconfig.
To launch the GUI, do 'make xconfig'. After the configuration is
completed, save and
exit the tool and config.vhd will be created automatically.
<br>
<br>
Alternatively, a pre-defined configuration can be installed for two
specific FPGA boards: gr-pci-xc2v and gr-cpci-xc2v. In
this case, set
the BOARD variable in the local <a href="Makefile">Makefile</a> to the
desired board type, and issue the command
'make config' to generate the configuration file.<br>

<h4><span style="font-family: helvetica,arial,sans-serif;">Simulation</span></h4>
<small><span style="font-family: helvetica,arial,sans-serif;">To
simulate the testbench, first compile the model for simulation. This
can be done automatically for three different simulators. Execute one
of the following commands:</span><br style="font-family: helvetica,arial,sans-serif;">
</small>
<ul style="font-family: helvetica,arial,sans-serif;">
<li><small>make vsim</small></li>
<li><small>make ncsim</small></li>
<li><small>make ghdl</small></li>
</ul>
<small><span style="font-family: helvetica,arial,sans-serif;">For vsim,
start the simulation with 'vsim testbench' and do 'run 100'. This
should print the current LEON3MP configuration:</span><br style="font-family: helvetica,arial,sans-serif;">

</span></small></h4>
<h4><small><span style="font-family: helvetica,arial,sans-serif;"></span></small></h4>
<small><span style="font-family: helvetica,arial,sans-serif;">To
synthesize and perform place&amp;route for any of the supported
FPGA boards, set the BOARD variable in the Makefile and issue the
appropriate make commands for your tool chain (see GRLIB User's Manual
for details).&nbsp; Alternatively, the design can be implemented using
the graphical XGrlib tool, which is started with 'make xgrlib'.<br>

For ASIC synthesis, scripts to synthesise LEON3MP towards the Atmel
ATC18 technology are provided. Run either atc18.dc or atc18.rc to
synthesise with Synopsys DC, or Cadence RC.<br>

on-chip debug support unit (DSU) makes debugging of target hardware
relatively easy. Both JTAG, serial (RS232) and ethernet-based debug links are
available, and can be used </span></small><small><span style="font-family: helvetica,arial,sans-serif;">download and debug
code. Debugging is controlled through the <a href="http://www.gaisler.com/products/grmon/grmon.html">GRMON debug

The LEON3MP test bench includes memory models of both boot-prom, sram
and sdram. To build memory images for these models, do 'make soft' .
Note: this will require that the bare-C compiler for LEON3 is
installed,
and /opt/sparc-elf/bin is added to the PATH.<br>
