where:\n\
time: A 32-bit value in milliseconds that represents the start time of the shift\n\
relative to the completion of the previous shift.\n\
type: A 4-bit value that determines whether the shift is a DR shift or an\n\
IR shift.\n\
value: The data associated with the shift. For IR shifts, it is a 32-bit value.\n\
For DR shifts, the length is determined by length.\n\
length: A 32-bit value that specifies the length of the data being shifted.\n\
This value should be equal to SLD_NODE_IR_WIDTH; otherwise, the value\n\
field may be padded or truncated. 0 is invalid.\n\
\n\
SLD_SIM_TOTAL_LENGTH: \n\
The total number of bits to be shifted in either an IR shift or a DR shift. This\n\
value should be equal to the sum of all the length values specified in the SLD_SIM_ACTION string\n\

SIM_N_SCAN:\n\
Specifies the number of shifts in the simulation model\n\
