SerialLite MegaCore Function
October 2005, MegaCore Version
This document addresses known errata documentation changes SerialLite MegaCore® function version 1.0.0. Errata design functional defects errors. Errata cause SerialLite MegaCore function deviate from published specifications. Documentation changes include typos, errors, unclear descriptions, omissions from current published specifications product documents. These documentation changes clarifications will incorporated into upcoming release SerialLite MegaCore function documentation.
SerialLite MegaCore Function v1.0.0 Issues
Altera identified following issues that affect SerialLite MegaCore function v1.0.0. "Some Configurations Operational Stratix Devices" page "Some Configurations Operational Stratix Devices" page "Retry-On-Error Problems with Packets Greater Than Segment Size" page "Cyclic Redundancy Code Checking (CRC) Cannot Enabled Some Configurations" page
Some Configurations Operational Stratix Devices
Some SerialLite MegaCore function configurations supported this release because preliminary model compiler support Stratix devices. simulation model compiler support mature, these configurations will operational.
Altera Corporation ES-92905-1.0
Preliminary
SerialLite MegaCore Function
Affected Configurations
This issue affects following configurations:
Unidirectional mode Asymmetric mode Broadcast transmitter only receiver only mode Lane rates above 3.125 gigabits second (Gbps) corresponding data path widths bits lane
Design Impact
Only symmetrical mode (including broadcast) with data rates below 3.125 Gbps operational this release SerialLite MegaCore function.
Workaround
There workaround.
Solution Status
affected configurations will available future releases SerialLite MegaCore function, released conjunction with Quartus® software releases service packs:
Quartus Version Service Pack-2GX Lane rates above 3.125 Gbps corresponding data path widths bits lane Quartus Version Service Pack Unidirectional mode Asymmetric mode Broadcast transmitter only receiver only mode
Some Configurations Operational Stratix Devices
Some SerialLite MegaCore function configurations supported this release because model support Stratix devices. simulation model support matures, these configurations will operational.

Retry-On-Error Problems with Packets Greater Than Segment Size
retry-on-error feature requires that segment transmitted uninterrupted (except link management packets) without being suspended continued. This version SerialLite MegaCore function suspends continues segments, does increment counter causing segment retransmitted three times before function times out.
Affected Configurations
This issue affects variations that have retry-on-error feature enabled with packets larger than segment size interleaved packets.
Altera Corporation
Preliminary
SerialLite MegaCore Function
Design Impact
link time outs data errors reported.
Workaround
Ensure that packets smaller than segment size when retry-on-error feature enabled.
Temporarily disable retry-on-error feature until this issue corrected.
Solution Status
This issue will fixed next release SerialLite MegaCore function.
Cyclic Redundancy Code Checking (CRC) Cannot Enabled Some Configurations
checking generation never enabled when transfer size equal number lanes transmitter receiver equal
Affected Configurations
This issue affects variations MegaCore function that have transfer size only lane transmitter receiver.
Design Impact
checking generation functional. Packets passed normally, other functionality unaffected. However, should data error occur, MegaCore function only detect error results 8B/10B data error (disparity, length violation, invalid control word).
Workaround
There workaround.
Solution Status
This issue will fixed next release SerialLite MegaCore function.
