10.1.4.2. Toolkit Parameters

The Toolkit parameters window has the following sub-tabs.

Tile Information

This lists a summary of the PCIe IP parameter settings in the PCIe IP Parameter Editor when the IP was generated, as read by the Debug Toolkit when initialized. If you have port subdivision enabled in your design (for example, x8x8), then this tab will populate the information for each core (P0 core, P1 core, etc.).

All the information is read-only.

Use the Refresh button to read the settings.

Table 166.  Available Parameter Settings
Parameter Values Descriptions
Intel Vendor ID 1172 Indicates the Vendor ID as set in the IP Parameter Editor.
Device ID 0 This is a unique identifier for the device that is assigned by the vendor.
Protocol PCIe Indicates the Protocol.
Port Type Root Port, Endpoint 1 Indicates the Hard IP Port type.
Intel IP Type intel_pcie_mcdma Indicates the IP type used.
Advertised speed 8.0GT, 16.0GT Indicates the advertised speed as configured in the IP Parameter Editor.
Advertised width x16, x8, x4 Indicates the advertised width as configured in the IP Parameter Editor.
Negotiated speed 2.5GT, 5.0GT, 8.0GT, 16.0GT Indicates the negotiated speed during link training.
Negotiated width x16, x8, x4, x2, x1 Indicates the negotiated link width during link training.
Link status Link up, link down Indicates if the link (DL) is up or not.
LTSSM State Refer to the P-Tile Avalon Streaming Intel FPGA IP for PCI Express User Guide Indicates the current state of the link.
Lane Reversal True, False Indicates if lane reversal happens on the link.
Retimer 1 Detected, not detected Indicates if a retimer was detected between the Root Port and the Endpoint.
Retimer 2 Detected, not detected Indicates if a retimer was detected between the Root Port and the Endpoint.
Tx TLP Sequence Number Hexadecimal value Indicates the next transmit sequence number for the transmit TLP.
Tx Ack Sequence Timeout Hexadecimal value Indicates the ACK sequence number which is updated by receiving ACK/NAK DLLP.
Replay Timer Timeout Green, Red

Green: no timeout

Red: timeout

Malformed TLP Status Green, Red

Green: no malformed TLP

Red: malformed TLP detected

First Malformed TLP Error Pointer
  • AtomicOp address alignment
  • AtomicOp operand
  • AtomicOp byte enable
  • TLP length mismatch
  • Max payload size
  • Message TLP without TC0
  • Invalid TC
  • Unexpected route bit in Message TLP
  • Unexpected CRS status in Completion TLP
  • Byte enable
  • Memory address 4KB boundary
  • TLP prefix rules
  • Translation request rules
  • Invalid TLP type
  • Completion rules
  • Application
 

PIPE PhyStatus (For F-Tile debug toolkit only)

0,1
Indicates the PMA and PCS are in reset mode.
  • 0: PMA and PCS are out of reset
  • 1: PMA and PCS are in reset

Event Counter

This tab allows you to read the error events like the number of receiver errors, framing errors, etc. for each port. You can use the Clear P0 counter/Clear P1 counter to reset the error counter.

Figure 63. Example of P-Tile Event Counter Tab

P0/P1 Configuration Space

This tab allows you to read the configuration space registers for that port. You will see a separate tab with the configuration space for each port.
