Greetings,
If I want to, for example, add a delay of 100 ticks before a line of code
executes in the function handleTimingReqMiss() in cache.cc, how do I go
about doing that?

I've looked into the schedule() function which is used to schedule events.
But can this function be used to simulate delays?

Generally speaking, you'll have to schedule an event and then do the
rest of the work in the event handler - something like that. You can't
just suspend code in the middle. You'll probably need to break things
into two functions to accomplish this.

Not by itself. You schedule an event at something like curTick() + 100.
When the event happens, a function gets called. So, the last step you
do before your wait is to schedule the event. The event handler is a
new function that does the rest of the steps. And any state you'll need
will need to be available, etc.
I guess my point is that it's doable, but non-trivial. You can't just
pause the gem5 code and pick it up again - it's an event driven system.
