使用 Linux 內建的指令 hexdump 就可以將 *.bin 轉換成 *.mem
讓 verilog 的 $readmemh 直接讀取
範例：8051 的 program : test.bin 轉換成 test.mem
$ hexdump -e '"@%07.7_ax " 8/1 "%02x " "n"' test.bin > test.mem
convert bin to mem for Verilog $readmemh

Simulate Amber on Mac OS
The Amber processor core is an ARM-compatible 32-bit RISC processor. The Amber core is fully compatible with the ARM® v2a instruction set architecture (ISA) and is therefore supported by the GNU toolset.
I would like to try run on my Mac Mini, so, I install Armber, tools and do some modification…
1. Download the Amber project from the Opencores Subversion server
$ mkdir ~/AmberInstallPath $ cd ~/AmberInstallPath $ svn --username YOUR_NAME -password PASSWORD co http://opencores.org/ocsvn/amber/amber/trunk
2. Install the GNU cross compiler
$ sudo port install arm-none-linux-gnueabi-gcc $ sudo port install gawk $ cd /opt/local/bin $ sudo ln -s gawk awk $ sudo ln -s arm-none-linux-gnueabi-gcc-2005q3 arm-none-linux-gnueabi-gcc
3. Install Icarus Verilog Simulator
$ sudo port install iverilog
4. Edit ~/.profile and add the following
$ export AMBER_BASE=~/AmberInstallPath/trunk $ export AMBER_CROSSTOOL=arm-none-linux-gnueabi
5. Make scripts executable and create a run link
$ cd $AMBER_BASE $ chmod +x hw/tools/*.sh sw/tools/*.sh $ ln -s ../tools/run.sh hw/sim/run
6. Create $AMBER_BASE/hw/tools/runIV.patch by following
--- run.sh 2011-04-29 08:47:23.000000000 +0800
+++ runIV.sh 2011-04-29 09:14:21.000000000 +0800

7. Create runIV script for iverilog simulator
$ cd $AMBER_BASE/hw/tools $ patch -o runIV.sh -i runIV.patch $ chmod +x runIV.sh $ cd $AMBER_BASE/hw/sim $ ln -s ../tools/runIV.sh runIV
8. If you see the iverilog compile error message for log2 function in next step, you could replace log2 by $clog2 to solve the problem.
9. Run a Hello-World Test with Amber 25
$ cd $AMBER_BASE/hw/sim $ runIV -5 hello-world
10. Hello-World simulation Result
