timescale related query ..

Thanks for the reply to both of you :)

Yea i find that if I issue "run 400" it shows the complete simulation result.

That means that when we are issuing "run" command, the compiler executes only uptil a certain time instant ....

And that's now a concern...how does the compiler decide this time for which simulation is done for a single "run" command.

One observation is , if I change the timescale to :

'define timescale 1ns/1ns

and then do : run

I get the complete results at once....ie at least upto simulation time 31 ns....

run

# 0 x

# 20 1

# 31 0

So the question that bothers is how we know what is this timestep that "run" command executes for ?

Thanks a lot again !
