PCIEbus Decode Examples

Let's show some examples while performing a PCIEbus Decode setup. Start by touching Analysis → Serial

Decode and selecting PCI Express as the Protocol for one of your Decodes on the main Serial Decode dialog.

Now, touch the corresponding Setup... button for the PCI Express decode. The Decode Setup... dialog is shown.

The Table should now be shown on the display grid.

SEQUENCES, TABLE ROWS, AND ANNOTATIONS

Following are some examples of the PCIe and 8b/10b Decode applied to a 2.5 GT/s Gen1 PCIe signal. In the first

example that follows, the transmitted signal of a single lane is captured. The captured signal is shown as F3 (F3 is

a math trace representing a Zoom of a Memory Trace). This signal is further zoomed and shown as the Z1 trace.

The PCIe decode is applied to the F3 signal. Since Z1 is a zoom of F3, it also shows the applied PCIe decode.

Furthermore, 8b/10b is additionally applied only on the Z1 trace.

2.5 GT/s Gen1 Startup.

Look to the left and right of the Zoom trace in the following screen-shot. The PCIe table has been turned on by

touching the View Table checkbox on the Decode Setup dialog. The table is showing all the PCIe decoded values.
