Thanks for the reply Dan.
I have another issue now, when I call my function "cal_act_Time()" for the track from other processor request ..nothing is getting printed
in_port(requestNetwork_in, RequestMsg, GlobalRequestToL2Cache) {
if (requestNetwork_in.isReady()) {
peek(requestNetwork_in, RequestMsg) {
cal_act_Time()
while access to the local L1 requests are recorded/printed correctly as following (same procedure as above).
in_port(requestNetwork_in, RequestMsg, L1RequestToL2Cache) {
if (requestNetwork_in.isReady()) {
peek(requestNetwork_in, RequestMsg) {
cal_act_Time()
So does this make sense, there should be global message transfers (I have also tried couple of benchmarks but got the same result)?? OR I am missing something there!!!

Messages arrive at L2s when that L2 does not (yet) cache the particular block (e.g., an L2 cache miss). When you execute L2cacheMemory[addr], there is an assertion that the line is present. If the line is not present, L2cacheMemory[addr] is meaningless. Hence, you cannot assume in your implementation of cal_act_Time() that the addresses associated with each message resides in-cache without first checking that this is the case.

List,
I was just trying to catch all the accesses to L2, either from its L1 or from other processors. So is that right, if I insert a function 'cal_act_Time(in_msg.Address)' for all global requests in the following way???
in_port(requestNetwork_in, RequestMsg, GlobalRequestToL2Cache) {
if (requestNetwork_in.isReady()) {
peek(requestNetwork_in, RequestMsg) {
cal_act_Time(in_msg.Address)........
......
where i am accessing L2cacheMemory[addr] in my defined function.
The problem with this is that when I use it in this way ..i get the following falied assertion
failed assertion 'loc != -1' at fn ENTRY& CacheMemory<ENTRY>::lookup(const Address&) [with ENTRY = L2Cache_Entry] in system/CacheMemory.h:502
I know that this assertion happens whenever the address is not in the cache...so does this mean i can not call my function here??
