May i know how to run the simualtion for 1ns
step. i gave it but as the inpurt is changing for fs etc., range - its
again doing for20 fs or ps etc., but forcefully i wantthe simulator to
calculate for 1ns interval - may i know how to do that -
plz let me know as my circuit has 10 lakh nodes and taking 10 days for simulaiton.
I understand that English is almost certainly not your first language, but your question makes absolutely no sense at all and so it's virtually impossible to give you an answer.
Please take extra care and re-formulate your question such that we might have some chance of understanding it.

Hi SunilI am guessing here so please correct me if I am wrong. Let me just try to help interpret the question:You have a design that has 1 million nodes and it currently takes 10 days to simulate. You found that the simulation time step is sometimes in fs or ps range and so would like to increase the time step to 1ns in an attempt to speed up the simulation. But you found that even after setting time step to 1ns, the actual steps shown in the log file are still in fs or ps range. Why is this so?

Hi,Sorry - I am little bit busy and so can't able to concentrate on what Iam typing - I have a circuit with 1 million components and i need it to simulate for 1 microsecond.But simulator is taking 10 days time - In
time analysis options, I have seen an option and kept step as 1ns and
max_step as 4 ns but the simulator again calculating for 30 fs and 3 ps
etc., So, is there any chance to tell the simulator to calculate only for 1 ns, 2ns, 3ns etc,. upto 1us.Or is there any other way to increase the simulation speed.regardsSunil
In reply to Sunil Kumar K:
You cannot constrain the "minimum" simulation time. If the simulator is taking very short timesteps, it does so in order to ensure it accurately follows the signals - if you were able to stop it doing this, it could easily become inaccurate as it would then miss vital detail.
What can cause short timesteps? Here's a few suggestions:
