Creating New Project - 2021.1 English

1. Click New Project on the Getting Started screen and click Next.
2. Enter the project name and project location.

   You can also select the .xpe file generated from Vivado for the import flow.

   
   
   
3. Clicking Next takes you to the part selection wizard. Select the temperature grade as commercial or industrial and process as typical or maximum and click Next.
   Note: If *.xpe import flow is selected, then architecture and device details are populated automatically from *.xpe file.
   
   
   
   Note: In the initial PDM 2020.2.2 release, only Kria SOM is supported and the K26C / K26I can be selected.
4. Click Next and the click Finish on the New Project Summary page. Your new project with all the default values will be created and ready to use.
5. Following is the summary sheet view in PDM after the new project is created.
   
   

   On the left panel, there are summary and other blocks tab for the device. The Summary tab has following sections:

   Part

   This panel is the summary of device selection and process setting for power estimation. You can change them in real time to see the impact on total power.

   Tip: For worst-case power estimation, use the maximum process. This process applies only for MPSoC devices as remaining on-board components always have worst case estimation.

   Power Summary

   This read-only table shows the total power estimation, junction temperature (Tj) and margin based on the environment table.

   Voltage & Current Requirements

   This table lists all the power rail requirements for the carrier card. Both current and voltage requirements are specified.

   Tip: This is a departure for a typical power estimation where the MPSoC rails would be displayed. The SOM has a pre-connected power delivery and so PDM simply shows the required inputs. PDM also has DRCs to ensure that the estimated power does not exceed the current limits of the K26 SOM power delivery.

   Environment

   Allows the user to either force the Junction temperature to a fixed value or specify the maximum ambient and effective ThetaJA for the thermal solution (obtained from thermal simulation).

   Recommended: Worst case junction temperature must be used until ThetaJA is obtained from thermal simulations. For more details see Kria K26 SOM Thermal Design Guide (UG1090).

   Thermal Loading

   This table lists out the power dissipated on the device, as well as on other external peripherals such as DDRs, power regulators, and boot devices available on SOM. The values in the thermal loading table must be used as inputs to a third-party thermal simulation.

   Estimation Section

   Under the estimation section on the left panel, there are device resources where you can provide input to the PDM about their usage, enable, and toggle rates.

At the bottom of the page, there is a Project Summary status which remains visible while viewing all of the PDM sheets. This information is added to provide a quick summary of the power distribution, thermal setting, and margin for the design.

Click on the show/hide button at the bottom right corner to hide this dialog box as needed.
