1. Clone Repository

git clone https://github.com/Galactic-FaaS/AlphaAHB-V5-Specification.git
cd AlphaAHB-V5-Specification

2. Explore Documentation

# Read the main specification
cat docs/alphaahb-v5-specification.md

# Browse instruction encodings
cat specs/instruction-encodings.md

# Check register architecture
cat specs/register-architecture.md

3. Run SystemVerilog Implementation

cd softcores/systemverilog/
make setup
make sim
make synth-vivado

4. Run Chisel Implementation

cd softcores/chisel/
make setup
make compile
make test
make verilog

5. Use Development Tooling

# Navigate to tooling directory
cd tooling/

# Build and test all tools
bash build.sh --test

# Use the assembler
python assembler/alphaahb_as.py examples/program.s -o program.bin

# Simulate the program
python simulator/alphaahb_sim.py program.bin

# Debug the program
python debugger/alphaahb_gdb.py program.bin

6. Run Tests

cd tests/
make all
