7.5 User-Defined Node Equations
Here you will see how internal logic nodes are created. In this example, there are four registers
(or nodes) to hold the initial count of the 4-bit down-counter, and four additional registers to
create the actual 4-bit down-counter (see Figure 38).
These nodes were created by:
1. Clicking the "Def Node.." button;
2. Naming the node; and
3. Delecting the type node (e.g., combinatorial, D-register, J-K register).
4. Clicking "Done."
Now you will see the main PSDsoft flow diagram that will guide you through the remaining
steps.
Note: You may view a summary report at this time by pulling down the "Report" selection in
the main menu bar at the top of the screen, then selecting "Design Assistant Summary." Your
report should match the one in APPENDIX C.
