Add Display Scanpath Command Dictionary

When DFTInsight generates a large schematic, it may take several minutes. You can terminate a lengthy generation by entering Control-C in the DFTInsight window. This causes the display to revert back to the previously viewed schematic. If you enter Control-C multiple times, the first Control-C terminates the schematic generation as described; DFTI traps and discards all others.

Arguments

∙chain_name

A required string specifying the name of the scan chain that you want to display in the DFTInsight schematic viewer. The scan chain must be a currently-defined scan chain.

∙SCI

An optional literal that causes DFTI to begin the scan chain display with the primary input gate of the chain_name. The primary input gate connects to the scan chain cell whose cell number equals the total number of scan cells minus one. This is the default.

∙begin_cell_position

An optional integer that specifies the position in a scan cell of the first cell that you want to display. The cell position must be an integer where 0 is the scan cell closest to the scan-out pin. You can determine the position of a cell within a scan chain by using the Report Scan Cells command.

∙SCO

An optional literal that causes DFTI to end the scan chain display with the primary output gate of the chain_name. The primary output gate connects to the scan chain cell whose cell number is 0. This is the default.

∙end_cell_position

An optional integer that specifies the position in a scan cell of the last cell that you want to display. The cell position must be an integer where 0 is the scan cell closest to the scan-out pin. You can determine the position of a cell within a scan chain by using the Report Scan Cells command.
