LatticeMico32 Development Tools

Overview

The LatticeMico32 System is used to implement the LatticeMico32 soft microprocessor and attached peripheral components in a Lattice FPGA. It is based on the Eclipse C/C++ Development Tools (CDT) environment, which is an industry open-source development and application framework for building software. The LatticeMico32 System contains two integrated tools (detailed below) that combine with Lattice Diamond or ispLEVER software to coordinate the building of an embedded processor system on an FPGA device and write the software to drive it. There are two versions of LatticeMico32 System available, one specific for ispLEVER software, and one specific for Lattice Diamond. These versions are functionally identical expect for the version of logic design software that they are installed into.

Mico System Builder (MSB)

• Generate platform description and associated HDL for hardware implementation
• Choose peripheral components to attach to the LatticeMico32
• Specify connectivity between peripheral components

C/C++ Software Project Environment (SPE) and Debugger

• Develop the code that runs on platforms created with MSB
• Interfaces via command line to compiler, assembler, linker, and debugger tools
• Lattice GNU-based tools provide appropriate compiler, assembler, and linker with optional debugger
• Target the Instruction Set Simulator (ISS) or hardware
