7.1.3.4. Using the Traffic Checker (BAS Example Design Only)
To use the Traffic Checker, the host software must follow the following steps:
- Allocate a block of memory in PCIe space and initialize the memory with sequential dwords.
- Program one of the windows in the Address Mapper to point to the block of memory allocated in step 1.
Steps 1 and 2 can be done by running the Traffic Generator as described in the topic "Using the Traffic Generator".
- Set the Traffic Checker’s Read Address register to point to the base of window selected in step 2.
- Set the Traffic Checker’s Read Count to the size of the block of memory allocated and initialized in step 1 (or 1MB if that area is larger than 1MB).
- Write to the Traffic Checker’s Read Control register to:
- Set the target_size to the size of the block of memory.
- Set the transfer size to the desired size, e.g. 512 bytes.
- Set the write_enable bit to start traffic generation.
- Read the Traffic Checker’s Read Count register to check that the desired number of transfers have occurred.
- Read the Traffic Checker’s Error register to check that no error occurred.
