Tcl Package and Version | Belongs to ::quartus::logic_analyzer_interface |
||
Syntax | begin_logic_analyzer_interface_control [-h | -help] [-long_help] -device_name <device name> -file_path <file path> -hardware_name <hardware name> | ||
Arguments | -h | -help | Short help | |
-long_help | Long help with examples and possible return values | ||
-device_name <device name> | Name of the device to be controlled | ||
-file_path <file path> | Path of the Logic Analyzer Interface (.lai) file | ||
-hardware_name <hardware name> | Name of the hardware that connects to the JTAG chain | ||
Description | Starts the Logic Analyzer Interface control sequence to query the Logic Analyzer Interface output pin state and change output pins state. The control sequence should be terminated with end_logic_analyzer_interface_control. The hardware and device name can be obtained by using get_hardware_names and get_device_names respectively from the jtag package. |
