3. Topology Workbench will open.
4. Click the DDR2_CLK tab or whichever tab that has a view of buffers and transmission lines, like the ones shown below.
5. Click on Start Transient Analysis to perform signal simulation on the circuit and see the waveform.
6. However, you may get a window pop up that says your IO (IBIS) blocks are of Receiver type. You can choose to continue
the simulation. Choose No.
7. Set the left-most device, U801 to Transmitter instead of Receiver by clicking on U801, then on the right panel, find the
Type filed under the Name column.
8. Where it says Receiver, double-click that word, then get the dropdown and change it to Transmitter. Now our circuit
should be set up to see how well our traces are carrying the high-speed signals.
9. Go back to the Topology Explorer Panel and under the Simulation section, click Start Transient Analysis.
