PDN Design Tool 2.0 Arria 10 Voltages

I am using the PDN Design Tool 2.0 (Version: 21 Pro, Build 09.12).

I selected the Arria 10, 10AS016C_U19.

I would like to change the voltage of VCCL_HPS to 0.95V the tool does not let me change the voltage to anything higher than 0.94V. I get the error message "Invalid Voltage! Check if 0.95 is valid for VCCL_HPS and all other rails that are in the same regulator group".

Both the data sheet and the Introduction tab show that the Arria 10 VCCL_HPS rail can be set to 0.95V. Is there something that I am missing here or is this just an error on the tool side?

    Hi,


    Try adding current of VCCL_HPS to another rail which is 0.95V.
