...\n\

(time,type,value,length))\n\

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\

\n\

SIM_N_SCAN:\n\

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

example:\n\

select index 7f\n\
