Agilex® 7 I-Series F-tile Multi Channel DMA IP for PCI Express Debug Toolkit Eye Viewer isn't working in Gen3x4 End Point mode in Quartus v24.2 Console (programmer version) in Windows.
The IP is identified with its x4 lanes, but parameters are not read and I cannot Start Eye Scan. See error message at the bottom.
I see 2 optional causes:
1. The sof file was created in Quartus 23.4 in a Linux server. If I use the Console version 23.4, will it solve it?
2. In signal tap I see LTSSM state is L0 with occasionally going through a recovery sequence.
I suspect a signal integrity issue and would like to check the Eye Diagram.
But the Console GUI states "ensure that LTSSM state = L0 before pressing the Start eye diagram".
I believe not being in L0 is one of the reasons one would want to observe the eye diagram.
Error message:
SEVERE: An error occurred while running script "refresh_channel_callback 0": ftile_debug_toolkit_mcdma: intel_pcie_ftile_mcdma_0: expected boolean value but got ""
- while executing
- "if { $lane_linked_up } {

- invoked from within
- "refresh_channel_callback 0"

Hi,
1. The sof file was created in Quartus 23.4 in a Linux server. If I use the Console version 23.4, will it solve it?
>> I am suggest you to regenerate the IP/Design in Quartus v24.2 and re-test the same sequence again.
>> Let me know if you are still seeing the same issue or linkup unstable.
2. In signal tap I see LTSSM state is L0 with occasionally going through a recovery sequence.
>> Can I know exactly what stage the Ltssm is looping at ? Can you please provide me the printscreen of the signaltap ?
>> or the hexa number of the ltssm will do.
3. I suspect a signal integrity issue and would like to check the Eye Diagram.
But the Console GUI states "ensure that LTSSM state = L0 before pressing the Start eye diagram".
I believe not being in L0 is one of the reasons one would want to observe the eye diagram.
>>One of the criteria to success start up the eyes test is to make sure the PCIe link is up.
>>The link status and ltssm can be checked by signaltap.
>> is this you own custom design ? or this is example design provided in our IP catalog ?
>> if you are using your custom make design, do appreciate if you can try out the example design and see if you monitor the same error or not.

The link_up and dl_up are high and stable in signaltap. LTSSM is looping thru stages in the stp file attached once every few seconds (L0 most of the time).
Knowing that, I tried to see the eye diagram for more info.
This is my FW design on an intel devkit.
