Hi, I went through the requests that were sent from L3 cache to DRAM and the responses from DRAM to L3. All the addresses (except the last 7, which end up being in the separate queue because simulate() limit reached), have been responded. So am unable to pinpoint the problem. Will delaying the responses create any issue, such that the simulation is getting over before time.
