Table 28.   GTS AXI Streaming IP Parameters: Interfaces Port 0/Interfaces Port 1 Settings Tab
Parameter Value Default Value Description
Enable PCIe* 0/ PCIe* 1 Control Shadow Interface
  • True
  • False
False

Enables the Control Shadow Interface. Host write to specific PCIe* configuration space register's bit is indicated through this interface.

Enable PCIe* 0/ PCIe* 1 Completion Timeout Interface
  • True
  • False
False

Enables the Completion Timeout Interface. Completion Timeout event is indicated through this interface.

Enable PCIe* 0/ PCIe* 1 Configuration Extension Bus Interface
  • True
  • False
False

Enables the Configuration Extension Bus Interface. You can add additional PCIe* capabilities using this interface.

When you set Enable PCIe* 0/ PCIe* 1 Configuration Extension Bus Interface to True, the following options are available:

PCIe 0/PCIe1 Standard next address pointer for PF 0x000 to 0x03F 0x00000000 Enable CEB pointer address for PF (DW address in hex).
PCIe 0/PCIe1 Extended next address pointer for PF 0x040 to 0x3FF 0x00000000 Enable CEB pointer address for PF (DW address in hex).
PCIe 0/PCIe1 Standard next address pointer for VF 0x000 to 0x03F 0x00000000 Enable CEB pointer address for VF (DW address in hex).
PCIe 0/PCIe1 Extended next address pointer for VF 0x040 to 0x3FF 0x00000000 Enable CEB pointer address for VF (DW address in hex).
PCIe 0/PCIe1 CEB REQ to ACK Latency Timeout value 1-256 100 Enable CEB REQ to ACK Latency Timeout value (in clock cycles).
Enable PCIe0/Configuration Intercept Interface
  • True
  • False
False Enables the Configuration Intercept Interface. You can intercept PCIe* configuration cycles using this interface.
When you set Enable PCIe0/Configuration Intercept Interface to true, the following options are available: PCIe0 CII REQ to ACK Latency Timeout value 1-256 100 Enables CII REQ to ACK Latency Timeout value (in clock cycles).
Enable Configuration Intercept Interface Monitor
  • True
  • False
False Enables the configuration intercept interface monitor.
Enable PCIe0/PCIe1 Virtio PCI CFG Interface
  • True
  • False
False Enables the PCIe0/PCIe1 Virtio PCI CFG Interface. Host read and write accesses to VIRTIO PCI Config Access Data register uses this interface for its alternate access functionality.
Enable PCIe0/PCIe1 Error Interface
  • True
  • False
False Enable the Error Interface
