The GUI displays a representation of the IP symbol on the left side and the parameter assignments on the right side, described as follows:
• Component Name: The component name is used as the base name of output files generated for the module. Names must begin with a letter and must be composed from characters: a to z, 0 to 9 and “_”.
Note: The name v_tc_v6_2 is not allowed.
• Optional Features :
° Include AXI4-Lite Interface : When selected, the core is generated with an AXI4-Lite interface, which gives access to dynamically program and change processing parameters. For more information, refer to Core Interfaces .
° Include INTC Interface : When selected, the core generates the optional INTC_IF port, which gives parallel access to signals indicating frame processing status and error conditions. For more information, refer to Interrupts .
- Interlaced Video Support : When selected, the core is generated with interlaced video detection and/or generation enabled.
- Synchronize Generator to Detector or to fsync_in : When selected, the timing generator automatically synchronizes to the detector or to the fsync_in input port. Otherwise, the generator runs in free-run mode.
