Operator Reference

Operator Library: Hardware Platform

This operator allows transmission of trigger packets to a CoaXPress over fiber (CoF) camera in VisualApplets design.

The operator generates trigger packets according to the trigger type provided on the input port I. The TX trigger is a 4-bit value, which represents the trigger type as defined in the CXP standard. Up to 16 different trigger types can be defined. Every valid input value on the port I results in transmission of a CoF trigger packet of the type equal to the provided value.

The operator docks to the TX master lane within the connection between camera and frame grabber. The Design Rules Check (DRC) checks whether a corresponding camera operator is instantiated and the master lane selection between the CoFCamera and the CoFTxTrigger operators matches. In case of errors, the DRC provides an error message, and the operator will get a red background overlay. There is no instantiation order, both CoFCamera and CoFTxTrigger can be used as desired. But to pass the DRC, both operators and the correct mapping to ports are required.

资源

该算子将 FiberConnection 参数设置镜像到 FPGA Device Resources 对话框中，作为只读参数。如果您从 Analysis 菜单中打开 FPGA Device Resources 对话框，则可以查看 FPGA 设备资源。设备资源为只读：

Depending on the allocated port, the resource is of the type Port[0] CoF TX Trigger Lane or of the type Port[1] CoF TX Trigger Lane with the index range from 0 to 3. The operator allocates always only one lane, as the transmission of trigger packets is running always over the master lane.

Signal Output Ports

There are several status signal output ports that indicate the processing state of the trigger packet. These ports provide information about what happens to the trigger signal during operation.
