[cv_dv_utils] rd_res_ex_fail signal is not driven in memory response model

[khandelwaltanuj]

Hello,

The signal rd_res_ex_fail is never driven. In the case of exclusive read, the memory response model should respond with either pass or fail. It does correctly in the case of write but it does nothing in the case of a read.

Thanks and regards

Hi @khandelwaltanuj, thanks for your interest in OpenHW. I assume you are referring to lib/cv_dv_utils/uvm/memory_rsp_model/memory_response_if.sv. Please confirm.

Hi @ludovicpion, can you comment?

Hi @MikeOpenHWGroup, it is indeed the lib/cv_dv_utils/uvm/memory_rsp_model/memory_response_if.sv
