1.5.2. Ethernet Packet Generator Script

The Ethernet Packet Generator script, eth_gen_start.tcl contains the parameters and settings to configure the Ethernet Packet Generator registers in this reference design.
Table 2.  Ethernet Packet Generator Script Parameters
Parameter Description
number_packet Sets the total number of packets to be generated by the packet generator.
eth_gen Enables or disables the packet generator.
length_sel Selects fixed or random packet length.
pkt_length Sets the fixed packet length. The packet length can be a value between 24 to 9600 bytes.
pattern_sel Selects the data pattern for the random packet length.
rand_seed Sets the initial random seed for the PRBS generator. This parameter is only valid when you select random packet length.
source_addr Sets the source MAC address.
destination_addr Sets the destination MAC address.
