21.13.1.54 run_frequency_monitor

Description

This tcl command calculates the frequency of any signal in the design that can be assigned to Live Probe channel A and displays the Frequency. The Frequency unit of measurement is in Megahertz (MHz).

It is run after setting the live probe signal to channel A.

run_frequency_monitor [-deviceName "device name"] \
                      -signal "signal name" \
                      -time "time in seconds to delay before calculate"

Arguments


Parameter	Type	Description
deviceName	string	Specify device name. This parameter is optional if only one device is available in the current configuration.
signal	string	Specifies the signal name assigned to Live Probe channel A. This parameter must be specified with the -time parameter.
time	integer or double	Specifies the duration in seconds to run frequency monitor. The value can be 0.1, 1, 5, 8, or 10.


Return Type	Description
String	Displays the Frequency with value-property format.

Error Codes


Error Code	Description
None	No recognized device 'device_name' is available for debugging.
None	Parameters are missing.
None	Parameter '-signal' is missing.
None	Parameter '-time' is missing.
None	Invalid monitor time specified. The values can be either 0.1, 1, 5, 8 or 10.
