Automation of VHDL compile/simulate process using GHDL and GTKWave. This script simulates testbench file, dumps .ghw file and runs GTKWave with it.

sim.sh # GHDL environment

# call this like:
# ./sim.sh psds_v2 2_1 top_level_tb 1000ns wave.gtkw

# params:
#	1 - lesson dir
#	2 - problem folder, e.g 2_2	
#	3 - model to test
#	4 - time interval to simulate
#	5 - gtkw setup file
