Connections, Jumper Switches, and Settings
Connect jumpers in the default settings to enable the MPM for SmartFusion design to function
correctly before powering up the boards.
• Jumpers from FB (feedback voltage) of each regulator for voltage trimming
• Jumpers for selection of PWM or SDD (see the MPM User’s Guide for details)
• Push-button switches to disable each regulator and simulate a power failure
Push-button fault injection switches SW8, SW11, SW15, and SW16 ground the enable pin of the
corresponding regulator, thereby injecting failure in the power subsystem. However, this enable pin
is also connected to the pin on the SmartFusion FPGA (MPM_REG1_EN, MPM_REG2_EN,
MPM_REG3_EN, MPM_REG4_EN).The FPGA could be damaged if configured to drive High on
the enable line when the fault injection switch is pressed. To avoid this, Actel recommends that the
FPGA pin driving this enable should be driving Low or tristated.
MPM Demo Design Description
The MPM demonstration design takes advantage of the processing power and programmable
flexibility of the SmartFusion™ intelligent mixed signal FPGA on the SmartFusion Evaluation Kit
or Development Kit. Connect either kit to the daughter card and download the software as described
to run the demo.
The daughter card consists of four regulated power supplies running from a 9 V supply.
• National switching regulators for 1.5 V and 3.3 V
• Linear Technology and Artesyn DC-DC regulators for 5 V
Using the MPM design one can do the following:
• Monitor voltage for all rails
• Sequence different power rails for power-up and power-down
• Trim and margin a voltage rails in a closed loop
• Sweep the output voltage (POT circuit to change resistor on feedback voltage)
• Induce failures by disabling the enable input of regulator (push-button to GND enable)
Power sequencing is done by sequentially asserting or deasserting channel enable pins for power-up
and power-down, respectively, and monitoring the associated channel voltage. All enable pins to the
regulator are active high.
