1 More about DesignWorks

2 Label a pin/signal

3 Select a device

4 Show Device Info

5 Show Pin Info

6 Set a pin’s attributes

7 Open the Test Vector

8 Input simulating data

9 Link Test Vector to active circuit

10 Blank Timing windows

11 Add all signals to timing

12 The simulator window

13 Simulating now

14 Waveforms in the Timing window

15 Enlarged waveforms

16 Workflow 1. Label all signals you need
2. Set all delays of gates you need 3. Design your own Test Vector 4. Add all signals to timing 5. Select “Step” or “Walk” to simulate 6. The waveforms and the output values should be in both Timing and Test Vector 7. Reset in both Test Vector and Simulator windows for the next run

17 To be stable In DesignWorks, the delay of a gate can not be greater than its input changes. For example, if the delay of a gate is 30, then in the $Time column of Test Vector, $D 40 is legal, but $D20 is illegal.
