Designing with SmartFusion involves three different types of design: FPGA design, embedded design and analog design. These roles can be filled by three different designers, two designers, or even a single designer, depending on company structure and project complexity. Actel has developed design tools and flows to meet the needs of these three types of designers so they can work together smoothly on a single project.

• FPGA Design―Libero® Integrated Design Environment (IDE) is Actel’s comprehensive software toolset for designing with all Actel FPGAs. Libero IDE includes industry-leading synthesis, simulation and debug tools from Synopsys® and Mentor Graphics®, as well as innovative timing and power optimization and analysis.

• Embedded Design―Actel offers FREE SoftConsole Eclipse-based IDE, which includes the GNU C/C++ compiler and GDB debugger. Actel also offers evaluation versions of
software from Keil and IAR, with full versions available from respective suppliers.

• Analog Design―The MSS configurator provides graphical configuration for current, voltage and temperature monitors, sample sequencing setup, and post-processing configuration, as well as DAC output.

The MSS configurator creates a bridge between the FPGA and embedded designers so device configuration can be easily shared between multiple developers.

SmartFusion intelligent mixed-signal FPGAs are uniquely suited to active motor control for permanent magnet motors, servo motors, series motors, separately excited motors and alternating current induction motors. A SmartFusion FPGA can actively manage multiple electric motors, including start and stop, control of rotational direction, speed and torque, protection against motor overloads or faults and active control using closed loop performance algorithms. SmartFusion on-chip resources allow you to monitor motor performance in real time with or without dedicated encoders, applying corrective control signals to maintain commanded direction, speed and torque and deliver precise motor position control.

Actel’s motor control partner, Power and Control Design, Inc., has produced a SmartFusion Motor Control Development Kit that enables demonstration and benchtop development of your world-class permanent magnet motor control products.

The kit includes five reference designs with source files:

• Trapezoidal using Hall effect sensor feedback

• Sinusoidal using Hall effect sensor feedback

• Sinusoidal with encoder feedback

• Sensorless trapezoidal with back-EMF feedback

• Ethernet interactive control of motors
