If you hope to validate your PCIe card, it's better to check the PCIe Card EM compliance test specification first. Agilent and Tektrionix also have published tutorial for PCIe card compliance test~.
Yanfeng, Thank you for the suggestion. It was very helpful.
I found that to perform PCIe card electrical compliance tests, you will use Compliance Base Boards (CBB) which serve as the test fixture. However, I wasn't able to find further information about the CBB. Any idea on where to look for this information?
Currently when I simulate PCIe transmitter circuit, I terminate the card edge to pair of 50 ohm resistors. Is this an acceptable approach?
yes~ but don't forget to do a suite of comprehensive simulations.
collect the transmitter and receiver ibis models and stack up detalils
if the transmitter and receiver is
connected through the connector collect the s parameters model of the
Map the muti project file through the connector if the transmitter and receiver devices are in separate boards
export hyp files from both boards connected map it through the connector connected with s parameter model
map the multi project file through the slot connector
enter the stack up data for the individual boards dk,er,signal and plane layers ,loss tangent details
of both the boards separately
set up power supplies for both the boards
set up differential pairs for both the boards
now map the ibis file model directory to the current project file
now select the tx device select the net to be simulated now select assign models and select the tx models and assign output as p and output inverted as n
assign rx models
and tx as input now select oscilloscope and select the eye simulation
and select the frequency based on the generation and set the eye mask constrains
now simulate and super impose with the mask to view the eye digram
