nclaunch ?

[pradeep]

Hi,

In modelsim after compilation i can load the design and view the
waveform, whereas in nclaunch it involves compilation, elaboration and
simulation, can i combine this compilation and elaboration as in
modelsim or can i avoid this intermediate elaboration step which i
don't find any use of it.

Happy New Year,

Pradeep. g

modelsim or can i avoid this intermediate elaboration step which i
don't find any use of it.

Write a script to execute all the command lines (ncvlog, ncelab, ncsim, etc)
..

You can invoke with ncverilog, which performs compilation, elaboration
and simulation in just one step, using command line options that closely
match Verilog-XL. Many users who are used to Verilog-XL follow this use
model.

It is mostly a matter of what you are familiar with. There is some extra
flexibility and control that is possible with separate elaboration and
simulation that some users find valuable in some situations.

MAY I KNOW WHAT ARE ALL THE EXTRA FEATURES OR FLEXIBILITY OF USING
SEPARATE ELABORATION?

THANK U

The main benefit is that elaboration generates a snapshot that you can
reload each time you want to run a simulation. This is very useful if
you are running large a simulation.

You can also generate multiple uniquely named snapshots with the
elaboration command. That might be useful if you have a lot of
simulations with different sdf settings for example.

Nclaunch was just implemented with the 3 separate stages. As others
have mentioned you can just have a script that takes care of the
elaboration step.
