Arguments
• primary_pin
A required string that specifies the name of the core logic pin that you want to
connect to the LFSR specified by lfsr_name.
• lfsr_name
A required string that specifies the name of the LFSR to which you want to
connect the primary_pin.
• position
A required repeatable integer that specifies the bit positions of the lfsr_name at
whose outputs you wish to place connections. A bit position is an integer
number, where 0 indicates the least significant bit position. The tool assumes
the output of the 0 bit position connects to the input of the highest bit position.
Examples
The following example connects an LFSR to a scan-in pin and another LFSR to a
scan-out pin:
add lfsrs lfsr1 prpg 5 10 -serial -in
add lfsrs misr1 misr 5 15 -both -out
add lfsr taps lfsr1 1 3
