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.
Example Usage
# Start a new control sequence.
begin_logic_analyzer_interface_control -hardware_name "USB-Blaster \[USB-0\]" -device_name "@1: EP1C20 (0x020840DD)" -file_path "lai_demo.lai"

# Query the output pin state.
puts "Current output pin state of instance auto_lai_0:"
puts [get_current_state_of_output_pin -instance_name "auto_lai_0"]

# Change input bank source to the output pins
change_bank_to_output_pin -instance_name "auto_lai_0" -bank_name "Bank 1"

# Query the output pin state.
puts "Current output pin state of instance auto_lai_0:"
puts [get_current_state_of_output_pin -instance_name "auto_lai_0"]

# Change input bank source to the output pins
change_bank_to_output_pin -instance_name "auto_lai_0" -bank_index 0

# Query the output pin state.
puts "Current output pin state of instance auto_lai_0:"
puts [get_current_state_of_output_pin -instance_name "auto_lai_0"]
