39.5.1. Register Maps

This section describes the register maps for the data pattern generator and checker cores.

Data Pattern Generator Control Registers

Table 390.  Data Pattern Generator Register Map
Offset Register Name
base + 0 Enable
base + 1 Pattern Select
base + 2 Inject Error
base + 3 Preamble Control
base + 4 Preamble Character (Lower Bits)
base + 5 Preamble Character (Higher Bits)
Table 391.  Enable Field Descriptions
Bit(s) Name Access Description
[0] EN RW Setting this bit to 1 enables the data pattern generator core.
[31:1] Reserved
Note to Table 29–4 :
  1. When the core is enabled, only the Enable register and the Inject Error register have write access. Write access to all other registers are ignored.The first valid data is observed from the Avalon® -ST Source interface at the fourth cycle after the Enable bit is set. When the core is disabled, the final output is observed at the next clock cycle.
Table 392.  Pattern Select Field Descriptions
Bit(s) Name Access Description
[0] PRBS7 RW Setting this bit to 1 outputs a PRBS 7 pattern with T [7, 6].
[1] PRBS15 RW Setting this bit to 1 outputs a PRBS 15 pattern with T [15, 14].
[2] PRBS23 RW Setting this bit to 1 outputs a PRBS 23 pattern with T [23, 18].
[3] PRBS31 RW Setting this bit to 1 outputs a PRBS 31 pattern with T [31, 28].
[4] HF RW Setting this bit to 1 outputs a constant pattern of 0101010101… bits.
[5] LF RW Setting this bit to 1 outputs a constant word pattern of 1111100000 for 10-bit words, or 11110000 for 8-bit words.
[31:8] Reserved
Note to Table 29–5 :
  1. This register is one-hot encoded where only one of the pattern selector bits should be set to 1. For all other settings, the behaviors are undefined.

This register allows you to set the error inject bit and insert one bit of error into the stream.

Table 393.  Inject Error Field Descriptions   (Note 1)
Bit(s) Name Access Description
[0] IJ RW Setting this bit to 1 injects error into the stream. If the IJ bit is set to 1 when the core is enabled, the bit resets itself to 0 at the next clock cycle when the error is injected.
[31:1] Reserved
Note to Table 29–6 :
  1. The LSB of the data beat is flipped at the fourth clock cycle after the IJ bit is set (if not being backpressured by the sink when it is valid). The data beat that is injected with error might not be observed from the source if the core is disabled within the next two cycles after IJ bit is set to 1.

This register enables preamble and set the number of cycles to output the preamble character.

Table 394.  Preamble Control Field Descriptions
Bit(s) Name Access Description
[0] EP RW Setting this bit to 1, at the start of pattern generation, enables the preamble character to be sent for Numbits cycles before switching over to the selected pattern.
[7:1] Reserved
[15:8] Numbits RW The number of bits to repeat the preamble character.
[31:16] Reserved

This register is for the user-defined preamble character (bit 0-31).

Table 395.  Preamble Character Low Bits Field Descriptions
Bit(s) Name Access Description
[31:0] Preamble Character (Lower Bits) RW Sets bit 31-0 for the preamble character to output.

This register is for the user-defined preamble character (bit 32-39) but is ignored if the ST_DATA_W value is set to 32.

Table 396.  Preamble Character High Bits Field Descriptions
Bit(s) Name Access Description
[7:0] Preamble Character (Higher Bits) RW Sets bit 39-32 for the preamble character. This is ignored when the ST_DATA_W value is set to 32.
[31:8] Reserved

Data Pattern Checker Control and Status Registers

Table 397.  Data Pattern Checker Control and Status Register Map
Offset Register Name
base + 0 Status
base + 1 Pattern Set
base + 2 Counter Control
base + 3 NumBits (Lower Bits)
base + 4 NumBits (Higher Bits)
base + 5 NumErrors (Lower Bits)
base + 6 NumErrors (Higher Bits)
Table 398.  Status Field Descriptions
Bit(s) Name Access Description
[0] EN RW Setting this bit to 1 enables pattern checking.
[1] LK R Indicate lock status (writing to this bit has no effect).
[31:2] Reserved
Note to Table 29–11 :
  1. When the core is enabled, only the Status register’s EN bit and the counter control register have write access. Write access to all other registers are ignored.
Table 399.  Pattern Select Field Descriptions
Bit(s) Name Access Description
[0] PRBS7 RW Setting this bit to 1 compares the data to a PRBS 7 pattern with T [7, 6].
[1] PRBS15 RW Setting this bit to 1 compares the data to a PRBS 15 pattern with T [15, 14].
[2] PRBS23 RW Setting this bit to 1 compares the data to a PRBS 23 pattern with T [23, 18].
[3] PRBS31 RW Setting this bit to 1 compares the data to a PRBS 31 pattern with T [31, 28].
[4] HF RW Setting this bit to 1 compares the data to a constant pattern of 0101010101… bits.
[5] LF RW Setting this bit to 1 compares the data to a constant word pattern of 1111100000 for 10-bit words, or 11110000 for 8-bit words.
[31:8] Reserved
Note to Table 29–12 :
  1. This register is one-hot encoded where only one of the pattern selector bits should be set to 1. For all other settings, the behaviors are undefined.

This register snapshots and resets the NumBits, NumErrors, and also the internal counters.

Table 400.  Counter Control Field Descriptions
Bit(s) Name Access Description
[0] SN W Writing this bit to 1 captures the number of bits received and number of error bits received from the internal counters to the respective NumBits and NumErrors registers within the same clock cycle.

Writing this bit to 1 after disabling the core will still capture the correct values from the internal counters to the NumBits and NumErrors registers.

[1] RST W Writing this bit to 1 resets all internal counters and statistics. This bit resets itself automatically after the reset process. Re-enabling the core does not automatically reset the number of bits received and number of error bits received in the internal counter.
[31:2] Reserved

This register is the lower word of the 64-bit bit counter snapshot value. The register is reset when the component-reset is asserted or when the RST bit is set to 1.

Table 401.  NumBits (Lower Word) Field Descriptions
Bit(s) Name Access Description
[31:0] NumBits (Lower Bits) R Sets bit 31-0 for the NumBits (number of bits received).

This register is the higher word of the 64-bit bit counter snapshot value. The register is reset when the component-reset is asserted or when the RST bit is set to 1.

Table 402.  NumBits (Higher Word) Field Descriptions
Bit(s) Name Access Description
[31:0] NumBits (Higher Bits) R Sets bit 63-32 for the NumBits (number of bits received).

This register is the lower word of the 64-bit error counter snapshot value. The register is reset when the component-reset is asserted or when the RST bit is set to 1.

Table 403.  NumErrors (Lower Word) Field Descriptions
Bit(s) Name Access Description
[31:0] NumErrors (Lower Bits) R Sets bit 31-0 for the NumErrors (number of error bits received).

This register is the higher word of the 64-bit error counter snapshot value. The register is reset when the component-reset is asserted or when the RST bit is set to 1.

Table 404.  NumErrors (Higher Word) Field Descriptions
Bit(s) Name Access Description
[31:0] NumErrors (Higher Bits) R Sets bit 63-32 for the NumErrors (number of error bits received).
