Package pad diameter and substrate pad dimension 

AM62P / AM62P-Q1 -> AMH pkg : ball diameter 0.4mm : substrate pad 0.35mm
The recommendation is 1:1 ratio between PCB pad and substrate pad.

Design Simulation files

Simulation files provided includes IBIS, IBIS-AMI, BSDL and Thermal model

AM62Px PDN Target impedance Values:

For frequencies above 50 MHz the board decoupling caps do not play a critical role. SoC and Package decaps (if any) will be dominant beyond 50 MHz

Note: We do not include Buck output inductance in PDN simulations.

For VDDS_DDR: we do not recommend using target impedance as the signoff for DDR.
Refer to the AM62Ax, AM62Px, AM62Dx LPDDR4 Board Design and Layout Guidelines which outlines all details of power aware SI/PI simulations
that need to be run. The eye mask checks from these power aware simulations are the signoff.

We only provide impedance targets for VDD_CORE. This information can be found under processor specific section "Example:AM62Ax" (starting on page 31) in the following document: www.ti.com/.../sprac76
As noted in the document, rails not listed are not simulated by TI due to low load transients. For more information, see the device-specific EVM layout for example implementation of these rails.
Other rails like the IOs are highly dependent on external peripherals. From the SoC perspective, if you look at the MAX current ratings for the IOs, the total current (after combining all the IOs of the same voltage) is still very low < 350mA so we don't simulate this rails/No data available.
Regarding your other questions related to PET, the supply names are not expected to match with processor (Example AM62A) pin names because the power estimates in the PET are itemized by supply groups. The power supply consolidation for these supply groups match the EVM.
