1. clone this project

git clone https://gitee.com/xunxiaohuii/juice_lc-3

or

git clone https://github.com/xiaoxiaohuixxh/juice_lc-3

2. download and compile verilator simulator
2.1 download verilator source code , install the tools of dependence for compile verilator

# Prerequisites:
sudo apt-get install git perl python3 make autoconf g++ flex bison ccache
sudo apt-get install libgoogle-perftools-dev numactl perl-doc
sudo apt-get install libfl2  # Ubuntu only (ignore if gives error)
sudo apt-get install libfl-dev  # Ubuntu only (ignore if gives error)
sudo apt-get install zlibc zlib1g zlib1g-dev  # Ubuntu only (ignore if gives error)

cd juice_lc-3/juicelc3/tools

git clone https://github.com/verilator/verilator   # Only first time
cd verilator
git pull         # Make sure git repository is up-to-date
git tag          # See what versions exist
git checkout aa86c777f4787db7d10fbbbb5019ed4d20a7fcfb  # switch to v4.220 version

2.2 compile the verilator source code

unset VERILATOR_ROOT  # For bash
autoconf         # Create ./configure script
./configure      # Configure and create Makefile
make -j `nproc`  # Build Verilator itself (if error, try just 'make')
./bin/verilator --version

the version for my verilator is

Verilator 4.221 devel rev v4.220-35-g2b91d764

3. design compile juicelc3 soc demo

pwd

is xxx/juice_lc-3/juicelc3/tools/verilator
switch to juicelc3 soc demo directory

cd ../../sim/verilator/jlc3_soc
chmod +x ../../../tools/LC-3_Assembler/nglc3asm

run design compile

make run # will be automaticlly run dc,compile asm code and run demo

➜  jlc3_soc git:(master) ✗ make run
