Migration Guide

If you are migrating from a previous release to the latest version, please refer to the link below:


A) New features:

1) New v6.1 8110.08 Gbps (Option 7A) line bit rate support for Stratix V and Arria 10 device families. See Figure 1.

B) Enhancements:

1) New transceiver analog reset acknowledge port "tx_analogreset_ack" and "rx_analogreset_ack" for line bit rate auto-negoatiation feature

2) Port name change for "cpri_10g_coreclk" to "cpri_coreclk" in 10.1376 or 8.11008 Gbps configuration

3) CPU Interface Avalon-MMM new addressing type option, option are "word" or "byte". See Figure 2

4) Removal of reconfig_clk, reconfig_reset ports and transceiver management interface when line bit rate auto-negotiation and startup sequence state machine are not enabled

5) Enable ADME, transceiver capability, control and status register access. This option expose the transceiver management interface, reconfig_clk/reconfig_reset ports and supercede 4). See Figure 3.

C) Bug fixes:

1) Line Bit Rate Auto-Negotiation during configuration from 10.1376 Gbps to other rates with following scenarios:

a) Assertion of rx_freq_alarm when the link reached Hyperframe synchronization

b) Link lost synchronization

2) Ethernet PCS with GMII with following scenario:

a) Not able to transmit Jumbo packet in 614.4, 9830.4 and 10137.6 Mbps

3) CPU Interface and registers with following scenario:

a) Write/read transaction to address other than 0x30, 0x34 and 0x38 does not assert waitrequest. Now change to compliant to Avalon-MM specification chapter 3.5.1

b) Register INTR (0x00) bit 16,17 and 18 incorrect _pending value

c) Register L1_STATUS (0x04) bit 8,9,10,11 and 12 incorrect _hold value

4) Rx state machine toggle between 0 and 1 when new scramble seed is transmitted with protocol version active at 2. De-scramble unable to retrieve new seed on Rx.

5) Simulator VCS or NCSIM may halt compilation due to error related to "always_ff" syntax
