Vector file for simulation

For complex simulations, you'll find that it is easier to create
a testvector file (.vec file) rather than creating the stimulus via
the waveform editor. Here's a sample .vec file that I used to test
part 1 of lab 2. It should give you the basic idea of the vector file
format. Consult the online help for more details.

File reg.vec:

Here's a sample .vec file. It was designed for Lab 2, part 1. It gives
you an idea of how to create a vector file to drive your simulations. For
complex simulations, it's faster to create a .vec file than to use the
waveform editor.

See the online help for further details.
