Made the following changes:
  • Changed descriptions in the register definitions.
-
Table 2.  10GBASE-KR IP Core Register Definition Changes v16.0Register definitions added or modified in version 16.0 for word address 0x4D0.
Bit RW Old Register Name New Register Name Description
1 RW dis_max_wait_tmr When set to 1, disables the LT max_wait_timer. Used for characterization mode when setting much longer BER timer values. The default value is 0.
14:12 RW equal_cnt [2:0]
Adds hysteresis to the error count to avoid local minimums. The following values are defined:
  • 000 = 0
  • 001 = 2
  • 010 = 4
  • 011 = 8
  • 100 = 16
  • 101 = 32
  • 110 = 64
  • 111 = 128

The default value is 101.

21:20 RW rx_ctle_vga_mode dfe_freeze_mode
Defines the behavior of DFE taps at the end of link training
  • 00 = do not freeze any DFE taps
  • 01 = Freeze all DFE taps
  • 10 = reserved
  • 11 = reserved

The default value is 01.

Note: These bits will be effective only when bit [19] is set to 0.
22 RW adp_ctle_vga_mode
Defines whether or not CTLE/VGA adaptation is in adaptive or manual mode. The following values are defined:
  • 0 = CTLE sweep before start of TX-EQ during link training.
  • 1 = manual CTLE mode. Link training algorithm sets fixed CTLE value, as specified in bits [28:24]. The default value is 1 for simulation.

The default value is 0 for hardware.

31:29 RW Manual VGA

Defines the VGA value used by the link training algorithm when in manual VGA mode. These bits are only effective when 0x4D0[22] is set to 1.

The default value is 4 for simulation. The default value is 7 for hardware.

22 RW adp_ctle_vga_mode
Defines whether or not CTLE/VGA adaptation is in adaptive or manual mode. The following values are defined:
  • 0 = CTLE sweep before start of TX-EQ during link training.
  • 1 = manual CTLE mode. Link training algorithm sets fixed CTLE value, as specified in bits [28:24]. The default value is 1 for simulation.

The default value is 0 for hardware.
