Hi Majid,
One way is the schedule the response of packet 1 to a later tick x( current
tick + 1), when the tick x is the system time, you have some sort of a flag
to check whether the packet 2 was serviced by L2 cache or not.
If no packet 2 had arrived in that time frame, you again delay the packet 1
response to y tick (y tick = current tick + n{number of ticks you want to
delay, I would suggest it to be 1})
