[755-1] Accusim force file

[Konstantinos Dovrolis <dovrolis@cs.wisc.edu>]

Folks,

For large designs it is obviously better to load
the Accusim forces from a file, rather than 
specifying them interactively.
I have added an example of an Accusim force file
at the web page (see the "Supporting Material for
the CAD tools" section).

The way that you can include this force file in
your Accusim simulation is as follows:

Before you run the simulation, select "File ->
Auxiliary Files -> Load Netlist File", and then
use the Navigator to select your force file.

The structure of the force file is like this:

vforce_0 A 0 PULSE 0 3.3 5e-09 1e-09 1e-09 1e-08 2e-08
vforce_1 B 0 PWL 0 0 5e-09 0 5.2e-09 3.3 10e-09 3.3 10.5e-09 0 
vforce_2 C 0 DC 3.3

Note that node 0 is the "ground" reference voltage.
In the above example, node A is a PULSE waveform that 
is between 0 and 3.3V, it starts at 5ns, it has a rise and
fall time of 1ns, an "ON" time of 10ns, and a period of
20ns.
Node B has a Piece-Wise-Linear waveform that is defined
as pairs of time-voltage points.
Node C has a DC specification.
