Determine Eye Diagram Performance for PCI Express Gen 2
When ADS opens use the Getting Started with ADS
dialog window to select the previously created pcie_wrk
workspace:
–– Create a fresh schematic window, for example by
clicking on the schematic icon in the ADS Main
window.
–– Name the schematic cell pcie and click OK.
–– Cancel the Schematic Wizard pop-up dialog window.
Create the series R, parallel C source termination using
the ideal R
and ideal C
components in the
Lumped-Components Palette and the Insert Ground
icon in the Schematic Toolbar.
R= 50 Ω, C=0.02 pF
We’ll add source/load impedance, transmitter and eye
probe to the pre-built DesignGuide PCI Express channel,
add crosstalk and simulate with and without equalization.
–– On the pcie schematic place a PCI Express Channel
model using the schematic’s menu: DesignGuide ► PCI
Express ► PCI Express Interconnect Models ► Full
Channel Model.
TIP:
Tool Bar Icon for Rotating a Selection.
–– Use the tool bar icon Push and Pop icons to explore the
newly placed PCIe_channel_model component design
hierarchy
