PLL number of Power and Thermal Calculator

How is the number of PLL of PTC tool displayed? There is an error, but since it is compiled and power consumption is calculated, can I assume that there is no problem?   Please see the attache...

Hello,

 

Thank you for reaching out to use. Allow me to further support you on this issue.

 

Thank you for providing details questions and I understood your concern. May I know if you willing to share the .qar file for this project to me through private chat? I would like to reproduce the error on my side.

 

It seems safe to say that this is okay since the design can be compiled and power calculated successfully, but I also need to have some verification from my side to see if the error is consistent in latest version.

 

Regards,
Aqid

Hello Aquid

Thank you for your support.

The attached .qar file is that you can see my concern.

If you have further more need, please let me know.

    Hello Aquid

    When I checked with version 25.3, the error disappeared as shown attached.
    From this, can I ignore the error displayed in PTC of version 25.1 and use it?
    At this moment, it is necessary to develop with v25.1 to match the version of IP made by 3rd Party.

      Hello MAC_Yossi,

       

      I can reproduce the same findings from my side using your .qar.

      Let me investigate this further, and thank you for bringing this to our attention.

       

      As for the result you obtained in the 25.3 version, since the error has disappeared, we can assume it shows no problem, maybe just wrong reporting in the previous version. I am checking on this.

       

      Can you confirm you are getting the same power calculated in both 25.1 and 25.3 versions?

       

      Regards,
      Aqid

        Hello Aqid

        Can you confirm you are getting the same power calculated in both 25.1 and 25.3 versions?

        As the result, it is not same power 25.1 and 25.3 because the difference is 0.002 W in Dynamic Power Dissipation as shown below.

         

        v25.1) Compilation Report > Power Analyzer > Summary

        Total On-chip Power Dissipation = 0.747 W

        v25.3) Compilation Report > Power Analyzer > Summary

        Total On-chip Power Dissipation = 0.749 W

         

        Also on PTC, there is little bit different power between both version as shown below. The setting is default.

        PLL IP was updated when changing from v25.1 to v25.3.

        v25.1) Total Power = 0.732

        v25.3) Total Power = 0.730

         

        Best Regards,
