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

Elaboration is an essential part in HDL. ModelSim does elaboration
when you fire the simulation. In NC-Sim, you can use a
script like the following:
ncvhdl -v93 -linedebug -messages design.vhd
ncelab -messages -access +rwc design:architecture_name
ncsim -gui -mess work_lib.design:architecture_name &

design.vhd is a file with the entity & architecture. If they are in separate
files, then
ncvhdl -v93 -linedebug -messages design_entity.vhd
ncvhdl -v93 -linedebug -messages architecture_name.vhd
ncelab -messages -access +rwc design_entity:architecture_name
ncsim -gui -mess work_lib.design:architecture_name &

I personally prefer scripts, which I also use in ModelSim because you generally
have more than one file to compile, and its easier to fire a script. I
generally do that from an emacs shell.
.... Yet another reason to use emacs..

Hi Pradeep g

I dont think U could combine the compilation and eleboration in NC Sim as a code must be compilable before it could be eleborated. they have to follow the steps as compile followed by eleboration and finally simulation.
