|Name||Power Sequence Auto Start (AN 491)|
|Description||Many consumer and industrial application systems do not require the FPGA to be powered on at all times. It is preferred to have a design in which the FPGA powers on intermittently, remaining off for most of the cycle. This is especially useful in portable battery-operated systems which can function on a non-continuous periodic task. |
Because MAX 10 FPGAs do not require a special power-on sequence, they can be switched on quickly (typically 200s, depending on the logic density). The ability to switch on and off quickly allows you to completely switch off the FPGA and switch it back on using external circuitry. The external circuitry can be a simple RC timer designed for the required delay.
However, if you implement considerable power off time, such a simple RC timer circuit is not practical. This requires very large values of R & C. A counter utilizing capacitors as memory elements extends the power-down period. The FPGA turns on for a very small duration during this power -down period, reads the value in these capacitors, increments the count, and stores them back again before powering down. This cycle repeats itself until the desired count is reached, at which time the FPGA switches on completely. When it switches on in the power-on period, the FPGA executes the task it was designed to accomplish.

Note: After downloading the design example, you must prepare the design template. The file you downloaded is of the form of a <project>.par file which contains a compressed version of your design files (similar to a .qar file) and metadata describing the project. The combination of this information is what constitutes a <project>.par file. In releases 16.0 or newer, you can simply double click on the <project>.par file and Quartus will launch that project.
Browse to the <project>.par file you downloaded, click next, followed by Finish, and your design template will be installed and displayed in the Project Navigator pane in Quartus.
Note: When a design is stored in the Design Store as a design template, it has been previously regression tested against the stated version of Quartus software. The regression ensures the design template passes analysis/synthesis/fitting/assembly steps in the Quartus design flow.
At the command-line, type the following command:
Once the process completes, then type:
