Fetch History RAM Cycle Information (Fetch History RAM Cycle Information (2D Pin States)) (G Dataflow)

Last Modified: July 23, 2019

Returns the acquired pattern information for the specified cycles. Use this node if the pattern is using the edge multiplier feature.

Cycle numbers represent tester cycles, each of which may consist of multiple DUT cycles. When using pins with mixed edge multipliers, pins may return Not a pin state for DUT cycles where those pins do not have edges defined.

pin list

List of pins from which to collect the History RAM cycle information.

datatype_icon

session in

Instrument session obtained from the niDigital Initialize with Options node.

datatype_icon

site

Site specified as a string in the form of siteN, where N is the site number. The node returns an error if more than one site is specified.

datatype_icon

samples to read

Number of samples to fetch. A value of -1 specifies to fetch all available samples.

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

position

The sample index from which to start fetching pattern information.

datatype_icon

session out

Handle that identifies the session in all subsequent NI-Digital node calls.

datatype_icon

cycle information

The returned History RAM cycle information.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
