This is a special case, where you can configure different AXI options to generate the desired AXI traffic for custom protocol.
- Traffic Gen
- Generates one set of traffic or repetitive traffic (One-shot, Repetitive)Based on your settings, the core internally creates a command set to meet your requirements.
- One-shot
- Internally created command set is executed once.
- Repetitive
- Internally created command set is executed repeatedly until
the core receives a stop pulse through
core_ext_stop.
- Traffic Pattern
- Length of AXI transactions, Random lengths with a minimum, maximum, and
average length value or Fixed length transactions.
When Address sweep is enabled, only a fixed traffic pattern is supported and all transactions are generated with this burst length.
The core tries to achieve the average length on a channel as the percentage of traffic share on that channel increases.
For example, the average length of transactions generated closely matches with the Vivado IDE setting when a percentage of traffic share is 50%. Rather than with a case where a traffic share is 5%.
- Transaction Type
- Read Only, Write Only or Read Write transactions.
- Inter Transfer Gap (ITG) Type
- Type of the gap between issuance of two AXI transactions. Fixed (Minimum
Fixed Gap in Clocks) or Random gap with a range of 0 to 1,024.Note: The IP in this mode always has a minimum six cycles delay between transactions, so the values from zero to six have no effect.
- Transaction Seed
- Seed value for the traffic generation. This allows you to regenerate the same traffic with the same seed.
