13.9.2. Traffic Generator Block Description

The traffic generator sends traffic through the external memory interface using the ctrl_amm interface.

Figure 170. Traffic Generator Block Diagram

ctrl_amm interface

The TG2 traffic generator replaces user logic as a master on the ctrl_amm interface, and sends traffic to the external memory interface.

tg_status interface

The tg_status interface mimics simple traffic generator status; you may assign these pins to LEDs or leave them unused.

tg_cfg interface

The TG2 Configuration Interface Mode parameter determines whether this interface is exported to allow a custom configuration master, or internally connected such that system-console becomes the master on this interface. This interface consists of several configuration and status registers, described in the User-Configured Traffic Pattern and Traffic Generator Status sections.
