attributes to said icons, wherein said attributes
include both data path and control path information
for a digital device graphically designed from said
placed icons.
11. A method for capturing a digital device as
a behavioral description and for converting the
behavioral description to a structural description,
said method comprising the steps of:
constructing a behavioral description of a
digital device upon a graphic display by graphically
connecting a set of symbolic icons drawn from a
fixed number of icons contained within an icon
library having fewer than fifteen icons;
mapping user-defined inputs to each of said
symbolic icons to define a graphical model having
data path attributes of said digital device;
representing said graphical model as a matrix of
data values corresponding to binary values at a
plurality of internal states within said graphical
model;
applying a set of input values to said matrix of
data values to modify said matrix and, simultaneous
with rising edges of a clocking signal, monitoring
the modified said matrix at select said internal
states;
determining events at the select said internal
states, and determining transitions of said events
at said internal states between said rising edges of
the clocking cycle; and
combining events and transitions of events to
produce a finite state machine having control path
information, and merging said control path
information with said data path attributes to
produce a structural description of said digital
device.
