The Lattice ORCAstra™ software is a PC-based graphical user interface which allows a user to configure the operational mode of a FPGA by programming control bits in the on-chip registers. This helps you quickly explore configuration options without going through a lengthy re-compile process or making changes to your board. Configurations created in the GUI can be saved to memory and re-loaded for later use. A macro capability is also available to support script-based configuration and testing. The GUI can also be used to display system status information in real time. Use of the ORCAstra software does not interfere with the programming of the FPGA portion of the FPSC.
To run ORCAstra on Windows 7, please read this document ORCAstra on Windows7 first.
All LatticeECP3, LatticeECP2M, LatticeSC/M, LatticeXP/2 and Lattice FPSC devices.
