MPSoC APM Hardcores Numbering xSDK

[so-lli1]

Hi,

In order to do some performance monitoring, I would like to use the internal APMs of the MPSoC. UG1085, Figure 15-1 shows where the APMs are located, further described in Chapter 15 - Axi Performance Monitor. However, when used with xSDK, the GUI names the APMs psu_apm_0-5 and I don't know where they are actually located since there is no numbering in the TRM.

How can I figure out which psu_apm the xSDK is referring to?

Regards,

Skip to bottom for solution. I just gave a way to use XSCT to extract this infor from HDF:

You can use the XSCT to open the HDF and read the APM in the design

You can dump the properties for each of these:

common::report_property [hsi::get_cells psu_apm_0]

So, If I just cross reference this register in the docs:

I updated the script to jump dump these:

hsi::open_hw_design hardware_description.hdf
foreach apm [hsi::get_cells *apm*] {
puts $apm
puts [common::get_property CONFIG.C_S_AXI_BASEADDR [hsi::get_cells $apm]]
}
hsi::close_hw_design [hsi::current_hw_design]

So, to clarify:

psu_apm_0: DDR_APM

psu_apm_1: APM_INTC_OCM

psu_apm_2: APM_LPD_FPD

psu_apm_5: AOM_CCI_INTC

This would be true for all designs as the address map on the PSU is hardened

@stephenm: Thank you for sharing the nice trick in order to figure out the base address of the APMs and not just the final solution. I wonder why Xilinx does not use the names directly when the address offset is hardcoded...

I have created a CR to have this added to the docs.
