Compiling Verilog on the Command Line with ModelSim

05 Apr 2015

Lately I have been working on some projects using verilog. My main development environment has been Altera Quartus II which works fine. However, when compiling in quartus we don’t always need to go through all of the sythesis and timing steps, instead one may just need to verify their source code is compilable.

The vlog compiler included with ModelSim can be used to quickly compile your HDL.

 # Add module sim onto your path
 $ PATH=$PATH:/usr/share/altera/14.0/modelsim_ase/bin

 # Create a library directory used by 'vlog', by default it looks for 
 # the 'work' library
 $ vlib work

 # Perform the verilog compile
 $ vlog dram_controller.v
