This defines each scan group that is contained in the circuit. A scan chain group is
a set of scan chains that are loaded and unloaded in parallel. The scan group name
will be enclosed in double quotes and each scan group will have its own
independent scan group section. Within a scan group section, there is information
associated with that scan group, such as scan chain definitions and procedures.
SCAN_CHAIN “scan_chain_name1” =
SCAN_IN = “scan_in_pin”;
SCAN_OUT = “scan_out_pin”;

The scan chain definition defines the data associated with a scan chain in the
circuit. If there are multiple scan chains within one scan group, each scan chain
will have its own independent scan chain definition. The scan chain name will be
enclosed in double quotes. The scan-in pin will be the name of the primary input
scan-in pin enclosed in double quotes. The scan-out pin will be the name of the
primary output scan-out pin enclosed in double quotes. The length of the scan
chain will be the number of scan cells in the scan chain.
