Command Dictionary Add Capture Handling
FastScan and FlexTest Reference Manual, V8.6_4 2-41
Arguments
You must choose one of the following three literals to indicate the data capture
handling behavior for the specified state elements:
•Old
A literal specifying that the source state elements determine their output values
for data capture by using the data that existed prior to the current clock cycle.
FastScan then passes the data on to the source state element’s sink state
elements. This option is the default behavior upon invocation of FastScan.
•New
A literal specifying that the source state elements determine their output values
for data capture by using the data from the current clock cycle. FastScan then
passes the data on to the source state element’s sink state elements.
•X
A literal specifying that the source state elements use the output values from
the current clock cycle for data capture unless the previous values are different
from the current values. If the values differ, the source passes unknown (X)
values onto the source state element’s sink state elements.
The following lists the four methods for naming the state elements on which the
function operates. You can use any number of the four argument choices, in any
order.
•gate_id#
A repeatable integer that specifies the gate identification number of the object.
The value of the gate_id# argument is the unique identification number that
FastScan automatically assigns to every gate within the design during the
model flattening process.
•pin_pathname
A repeatable string that specifies the name of a pin within the design.
