Hi @AhmedAmrAbdellatif1, simply generating atomic instructions is insufficient. Typically there will be interactions between your core and the memory sub-system that a test-program running on the core cannot check, so your testbench needs to model and check that the right thing(s) happen (example). Before spending a lot of time getting riscv-dv to generate atomic instructions, you can probably do a lot of useful work with manually written test-programs.
Once you are satisfied with that, you could try extending class riscv_directed_instr_stream
to generate atomic instructions with riscv-dv. Here is an example of how that can work.
Could i use spike to help me with testing the behavior? if yes, could you guide me how to use it to do so?

It depends on the needs of your core. Spike has a limited modelling of the interface(s) to memory and only models what the ISA does.
if yes, could you guide me how to use it to do so?
Sorry, I do not use Spike a lot. I did find the README helpful.
I'm working on a GP to design a RV64IMAC, and i want to use the DV to test my design, but there's no test that generates atomic instructions, can someone help me?
