Andreas,
I think my question is still not clear.
I'm working on GEM5 to provide my company design team a tool that would
simulate their models. Our mainly working is interconnection model. I am
trying to model a given architecture with some router models.
By extrenal object I mean:
When I giv
Do you mean that the tick value does not change over the simulation time?
Once it is fixed, its value never changes. Am I right? So the tps_value is
always set to true and never to false.

Hi Anny,
I still do not understand what you are referring to. I think you have to
try and up-level your question a bit.
As my original response stated, the global time is discretised into Ticks,
and all objects will thus convert any cycles etc to a value on this
discretised timescale, just like a
I mean asynchronous object.
The main question is :
Is there a funtion that computes the suitable tick value for the objects in
the system?

Hi Anny,
I do not understand the case you are describing. What “external” object
are you referring to?

Hi Andreas,
I have one more question.
In ticks.py, there is a variable tps_fixed initialized to false. This value
is set to true in fixGlobalFrequency function. Is there a case where this
value is not changed to true?
Suppose that tick value is fixed to 10 ps, when an external object that
comes
Ok thank you Andreas for your reply,

No. There is a global time, and we discretise it into units of Ticks, by
default ps. You can set if to any arbitrarily fine-grained quanta.

Hi Anny,
As I said in my last e-mail response:
"At run time, we turn relative time in cycles into absolute time when
scheduling/executing events in the system.² Thus all events will be
scheduled on an absolute time scale.
and
"There is a global absolute time in gem5, and it is measured in the

Hi,
Thank you Andreas. The tick value may not be prefixed because it may be
equal to the pgcd of clock periods of all objects in the system, Am I rignt?
Othewise, this is not accurate.
I have another question about this:
In gem5, objects can have clocks or not (no clocked objects exist). What

Ticks is the basic unit of time in gem5. gem5 uses this for
synchronization. Every system cycle is made up of n number of ticks ticks.
For a system unit with frequency = 2 GHZ, one cycle = 500 ticks

Hi all,
I have a question about clocks on gem5. In gem5, it seems that there is a
global simulation clock and every simObject has a clock domain. The eventq
is sorted in time. When two objects with two different clocks schedule two
events on eventq, how the order is determined since the two object
14 matches
