Description

Drive the JTAG controller into the Run_Test_Idle state for a number cycles specified with the -num_clocks

option.

Example

# List all available programming hardware, and select the USB-Blaster.

# (Note: this example assumes only one USB-Blaster is connected.)

puts "Programming Hardware:"

foreach hardware_name [get_hardware_names] {

puts $hardware_name

if { [string match "USB-Blaster*" $hardware_name] } {

set usbblaster_name $hardware_name

}

puts "\nSelect JTAG chain connected to $usbblaster_name.\n";

# List all devices on the chain, and select the first device on the

# chain.

puts "\nDevices on the JTAG chain:"

foreach device_name [get_device_names -hardware_name $usbblaster_name] {

puts $device_name

if { [string match "@1*" $device_name] } {

set test_device $device_name

}

puts "\nSelect device: $test_device.\n";

# Open device

open_device -hardware_name $usbblaster_name -device_name $test_device

# Retrieve device id code.

# IDCODE instruction value is 6; The ID code is 32 bits long.

# IR and DR shift should be locked together to ensure that other

# applications

# will not change the instruction register before the id code value is

# shifted

# out while the instruction register is still holding the IDCODE

# instruction.

device_lock -timeout 10000

device_ir_shift -ir_value 6 -no_captured_ir_value

puts "IDCODE: 0x[device_dr_shift -length 32 -value_in_hex]"

# Goto the Run_Test_Idle state and stay there for 8 cycles.
