Other Parts Discussed in Thread: AM6441,
Hello,
I'm looking at the AM64x Power Estimation Tool spreadsheet and have a couple questions / clarifications.
1. There doesn't seem to be any way to disable the CPU cores. For example, if I wanted to model the AM6441 use case, how do I disable A53 core 1? Do I simply set it's utilization to 0%? That actually doesn't make a lot of sense, at least based on how TI has typically done these spreadsheets. Does the spreadsheet magically recognize 0% to mean clock gate / disable the core? Or is 0% equivalent to clock gating? This same question goes for all the cores, A53, R5F, M4, PRU. Even if 0% means inactive, I would suggest an improvement by simply adding an enable/disable option for each. That's more intuitive.
2. Is TI planning to create a companion app-note to the power estimation tool that explains the settings?
3. There's a setting called 'Power Estimation Mode' which can take on one of two values, Typ, and Max. Can you describe what these mean? Is max referring to the hot end of the silicon process spectrum?
4. The AM6442 datasheet shows DDR4/LPDDR4 at up to 1600 MT/s. The power spreadsheet doesn't have this option. Is there a reason, this is an important one since DDR is a big part of the power.
5. This might be nit-picking but under the LVCMOS IO section, there are two MCU UART rows and two MCU SPI rows but they are named the same, shouldn't it be something like MCU UART0 then MCU UART1? Likewise MCU SPI0 and MCU SPI1?
Thank You
