Introducing wait/delay in end of elaboration of start of simulation

[Nitin_S]

Hello all,

This is very basic question and I know its not possible, but still I need to put some delay or wait in start of simulation/end of elaboration.

I will give you the background, In end of elaboration i an initializing the value to a pin, and that pin is quite required for reset vector address.

In start of simulation I am opening my gdb, which which stop at my reset vector address, but it seems the gdb is not updating the reset vector value, so I need a small delay.

Is it possible?

Any suggestion will be very helpful :)

Thanks and Regards,

You cannot have a delay in end_of_elaboration() or start_of_simulation() since those are callback functions outside of the (timed) simulation cycle.

One thing  you could do is to start the gdb within a SC_THREAD where you have a wait(SC_ZERO_TIME) to let the updates settle:

void start_gdb_thread(){
	wait(SC_ZERO_TIME);
	start_my_gdb();
}

Thanks Eyck 🙂
