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.
