data

Specifies the sequence in which the bits are to be arranged. It can be used to create both simple and nested bit patterns.

In case of nested patterns, ensure that the specified value conforms to the following rules:

• A pattern multiplier is preceded only by a space character or an opening bracket.
• Every opening/closing bracket has a corresponding closing/opening bracket.
• A closing bracket for a pattern to be multiplied is followed only by a space character or a closing bracket.

For example, if data = 4(01) 2(11001) 10, then the final bit sequence is: 01 01 01 01 11001 11001 10.

Seed

lfsrseed

For PRBS source, lfsrseed is an integer array which sets the initial state of the LFSR. Array elements sets the locations of non-zero bits. Locations are 1-based and ordered from MSB to LSB of the LFSR. For example, assume lfsrtaps=[6] and lfsrseed=[1 3 5]. The width of the register is then 6 bits and the initial state is 101010.

Threshold

triggerthreshold

For PRBS, when triggerthreshold is set and the source is instantiated with optional control terminals (terminals 3 and optionally 4; if terminal 4 is unspecified it is assumed to be connected to ground), triggerthreshold defines the crossing threshold for the trigger event. The event causes the emission of the next PRBS pulse.
