13.9.4. Configuration and Status Registers

You can configure the user traffic pattern by writing to configuration registers that influence the resulting traffic pattern.

Configuration registers that govern the resulting traffic pattern affect one of the following aspects of the pattern:

  • Test duration / Instruction pattern
  • Address pattern
  • Data pattern
Note: This section describes the registers that configure a traffic pattern as seen on the ctrl_amm interface.

0x640 TG_ADDR_FIELD_RELATIVE_FREQ 16 6 Readable and Writeable Address Pattern Frequency setting for both reads and writes. Consists of 6 registers, where each register specifies after how many read or write operations an address field generates a new address. To understand relative frequencies of address fields, refer to Address Generator Relative Frequencies.
0x680 TG_ADDR_FIELD_MSB_INDEX 6 5 Readable and Writeable Address Pattern Most significant bit (MSB) position setting for both reads and writes. Consists of 5 registers, where each register specifies the index of the MSB of the corresponding field. This ties each of the 6 address generators to a bit range of the generated address. Field number 5 is implied to have an MSB index of AMM_WORD_ADDRESS_WIDTH-1 and need not be specified. The width of an address field is derived from these MSB indices. To understand MSB indices of address fields, refer to Address Generator MSB Indices.
0x6C0 TG_BURSTLENGTH_OVERFLOW_OCCURRED 1 1 Read Only Status A value of 1 indicates that an attempt was made to write outside of the address space. This occurs when the current address plus the burst length is greater than the total address space. This is an invalid operation and the burst length is clipped to prevent an invalid operation on the Avalon® interface.
0x700 TG_BURSTLENGTH_FAIL_ADDR_L 32 1 Read Only Status The address at which the burst length overflow was attempted (lower 32 bits). The value at this register is valid only if TG_BURSTLENGTH_OVERFLOW_OCCURED is 1.
0x704 TG_BURSTLENGTH_FAIL_ADDR_H 32 1 Read Only Status The address at which the burst length overflow was attempted (upper 32 bits). The value at this register is valid only if TG_BURSTLENGTH_OVERFLOW_OCCURED is 1.
0x740 TG_WORM_MODE_TARGETTED_DATA 32 ceil(TG_RDATA_WIDTH/32) Readable Status Checker Received data from the targeted read. Targeted read data is set when WORM mode is enabled and the result of the second read to the first fail address occurs. Bus Width = TG_RDATA_WIDTH.

In the table above, some configuration settings and status information can fit within one 32-bit register, while others are broken into several registers. The Starting Address column indicates the address of the first register in the set while the Number of Registers column indicates the number of registers located after the start address.

For example: TG_PPPG_SEL occupies 8 registers when TG_NUM_DATA_GEN=8, so the data can be accessed by reading from addresses 0x5C0, 0x5C4, … 0x5E0.
