verilog-6502-ledblink

This is a template/sample project for using a 6502 core in a SoC type fashion.

Features

• Arlet Ottens' 6502 core
• 1K block ram (increase as needed)
• 1K block rom, loaded with a hex file (increase as needed)
• A rough gpio module that's designed to blink a number of leds
• A simple 6502 assembly project that blinks some leds (requires acme and some unix tools)

Requirements

• Altera/Intel Quartus (for the included projects anyway)
• FPGA hardware and/or verilog simulator
• ACME cross-assembler
• Unix environment for building the hex file (WSL works fine on Windows)

Getting started

• Clone the repository with submodules: git clone --recursive https://github.com/desaster/verilog-6502-ledblink
• Compile the assembly project in asm/, resulting in a ledblink.hex file
• either: Open the project for your board in Quartus from target/<board>/project/verilog-6502-ledblink.qpf
• or: Create your own project, placing your project in target/<board>/project/ and board specific verilog files in target/<board>/hdl/

When building

• Make sure RAM and ROM are inferred properly into blockram/rom.
