I am doing a project sq100 related , we created block design using vivado
BD(Block Design) : one AHB-master , one AXI-slave, interface . Zynq 7000 process and one AXI-interconnect .
my doubt is : with this BD i integrated PL and generated bit stream. But how to test internal PL memories using PS .

Block RAM (BRAM) contained in the Programmable Logic (PL) can be accessed from the PS via the AXI Bus, given that there is some AXI Slave present in the PL which does connect to the BRAM in some way.
Options here are ...
Hope this helps,

As you said AXI interface indirectly connected to BRAM , but in address editor am not getting any base address for this AXI-slave on PS side .

Now I directly connected AXI slave from Processor , using GP0 slave .
But I am unable to get exact base address of this GP0 slave .
Please help on this .
Thank you .

If you connected to the GP0 slave port of the PS, then your interface acts as AXI Master and can access all of the memory. This is another option, but not the one I suggested. What I suggested was to use an AXI Slave connected to one of the GP Master ports to map the BRAM into the PS memory space.
Hope this clarifies,

Thank you so much, but i am little bit confusing ,
In PL side AXI master interface is there, so i enabled S_AXI_GP0 in PS and i connected these two, is it correct and how to generate communication on this AXI bus.

No problem, happens ... :)

They do not look connected in your block diagram though ...
is it correct and how to generate communication on this AXI bus.
Basically yes, but you need to have the same AXI protocol on both sides or use some kind of protocol converter (like for example the samrt connect).
Hope this helps,
