Enhanced the netlist parser and cleaned pong.c. Also added a folder nl_examples which contains standalone netlist examples. [couriersud] The examples have a ".c" suffix. In eclipse, I get automatic syntax parsing and error notifications. The parser treats "#" preprocessor defines/includes just as comments. All of these examples can be run through nltool: ./nltool -f nl_examples/opamp.c -t 1 -l OUT runs the opamp example for 1 second of emulation time and logs the terminal named "OUT" to "netlist_log_OUT.log". I'll post a simple script to the list to visualize those logs using gnuplot.
