No write request initiaed to memory system(bug?)

After running the example_inst.trace, I find it quite strange that there is no write_requests initiated, I dont think this is normal is the a bug?

Write requests are first directed to the LLC. If the requested data is not found in the LLC (i.e., a write miss), the request is treated as a memory read, and the corresponding data block will be fetched into the LLC (refer llc.cpp). Write requests are sent to the memory system only when a dirty block is evicted from the LLC.
