Normal Mode Test

In Normal mode, the MAC or UDP pattern generator constructs and initiates TX packets through the TX path of the MAC core.

Figure 1. Normal Mode Data Flow

Table 1. Normal Mode Macros
Macro Name Description
PAT_NUM Number of packets to transmit.
Setting PAT_NUM = 0 enables unlimited packet transmission.
PAT_DLEN Length of the UDP/ MAC pattern transmit packet (payload length).
PAT_IPG Interpacket gap (IPG) between frames. One IPG unit equals 8ns.
PAT_TYPE Type of packet pattern:
  • 0: MAC pattern
  • 1: UDP pattern
The following are the criteria for the test:
  • If PAT_NUM = 0, the aFramesTransmittedOK counter continues to increment until it wraps around at 0xFFFF
  • If PAT_NUM is non-zero, the aFramesTransmittedOK counter matches the programmed PAT_NUM.
  • The ifOutErrors counter remains at 0.
  • The captured packet in Wireshark matches the transmitted pattern.
