Reaed their doc, theer are atleast 3 ways - 1 to create SHM and then convert to VCD via shm2vcd command. Another is via $dumpvars, 3rd option is to use TCL script as:

Code: 
database -create -vcd -default
probe -add -vcd / -depth all
run
exit

Pass this to ncsim as:

ncsim -tcl dump.tcl

Tutorial - google it, you will find it.
