A. Measuring Static Power

3.1. Early Power Estimator Input Fields

Input fields let you enter information about the device, board, and design for which you want to calculate power estimates. Some input fields let you type values directly, and others let you select from a list of values on a dropdown menu.

Direct Entry Input Fields

Some fields allow you to type values directly into the field. Such fields are often used for data that has a large range of possible values, such as clock frequencies or resource counts.

If the value you enter does not pass legality checks, or is inappropriate for the field, the system displays an error message. The error message may indicate the conditions under which a value is invalid, and specify a valid range of values. An example message is shown below. In this example the user has entered a temperature that is outside the allowed range for a selected family, device, transceiver grade, device grade and package combination. The error message also indicates the allowed range of 0 to 100. After the user clicks OK, the field value reverts to its previous value.

Figure 2. Example Error Message

If a specific type of numerical value is expected and you enter a text value or a wrong numerical type, the resulting error message indicates that the entered value cannot be converted to the expected data type. An example is shown in the figure below. In this instance, the user has entered a fractional value (37.5) in a field that expects an integer value representing the number of RAM blocks. After the user clicks OK, the field reverts to its previous value.

Figure 3. Invalid Value Error Message

Many fields have restrictions based on the selected family and device. To better understand restrictions on field values, refer to the relevant field description in this user guide, to the tooltip in the appropriate EPE worksheet, or to the Cyclone® 10 GX Device Handbook.

Note: Although the Early Power Estimator restricts many field values, the restrictions are not exhaustive. In order to provide power estimates at early design stages, when many details of the design are still unknown, the EPE uses a simplified device model that does not account for all possible restrictions. The EPE may accept as legal some values that might not be accepted as legal by the Quartus® Prime software.

Dropdown Input Fields

Input fields that have a limited number of valid values often employ a dropdown menu. A dropdown menu is denoted by a downward-pointing arrow that appears when you click in the field. Click in the field a second time to display the list of allowed values. Click the desired value to select it and populate the field. An example dropdown input field is shown in the following figure:

Figure 4. Dropdown Input Field

You can also type a value directly into an input field that has a dropdown menu. To directly enter a value, select the field and press F2, and then type the desired value. The value that you enter must be identical to one of the available values on the dropdown menu, otherwise you will receive an error message.

Figure 5. Value Entered is Not Valid

You can click Retry in the error dialog to enter a new value, or click Cancel to revert back to the last legal value. Clicking Help invokes the generic Excel help window.
