I am a newbie in FPGA development and currently struggling on bringing up a PCIe Datapath card developed based on Cyclone IV GX and PCIe Hard IP(parameterized in QSYS) .
To debug the problem, I am trying to tap LTSSM signals with SignalTap, (using Quartus 11.1) but can't find the node in Node Finder. Should I search it with different name? I have tried both Node Finder and Technology Map Viewer.
Any comment is appreciated.
I had found out the LTSSM signal in SignalTap Node Finder.
There are a few steps I had done before i found the LTSSM signal:
1.Set the BT_Q11-2.bdf file as Top-Level Entity
2.Start compilation on the design
3.Click to the Signal-Tap II Analyser
4.Double click to have the node finder in Signal-Tap.
5.List all the node
6.Search the *ltssm* node in the "Named" coloumn.
Then you may see the LTSSM signal as picture below.
