how to access internal memory in FPGA from HPS using python ?

hi.

I am new to FPGA design. i am struggling to access internal memory from HPS using python. I have created .qsys and a VHDL to store data in a shared memory but it gives a compilation error "fitting error/ need larger device" ( but i didn't did any such huge thing). please go through the attached .qsys file .vhdl file and python script that i am using to access shared memory. and let me know what i am doing wrong

thank you.
