Errata Sheet
Introduction
This document addresses known errata and documentation issues for the Altera® SerialLite MegaCore® function version 1.1.0. Errata are functional defects or errors, which may cause the SerialLite MegaCore function to deviate from published specifications. Documentation issues include errors, unclear descriptions, or omissions from current published specifications or product documents. Table 1 shows the issues that affect the SerialLite MegaCore function v1.1.0.
Table 1. SerialLite MegaCore Function v1.1.0 Issues Section
Functional Behavior
Issue
The Channel Multiplexing Options for the Priority Data Port Are Nonfunctional. The Training Sequence Appears on the Atlantic Receive Interface
Quartus II Issues Demonstration Testbench
The Quartus II Software Does Not Merge Transmit Phase-Lock Loops (PLLs) for Multiple Function Instantiations The Demonstration Testbench Fails in Unbalanced Configurations
Functional Behavior
This section describes the configuration issues.
The Channel Multiplexing Options for the Priority Data Port Are Nonfunctional
When the Multiplex channels parameter is turned on for the priority data port, the THADR port does not drive any internal logic.
Affected Configurations
This issue affects the MegaCore function variations that use the priority data ports and have the Multiplex channels parameter turned on.
Altera Corporation ES-081205-1.1
Functional Behavior
Design Impact
The channel number is not transmitted on the address bus.
Workaround
Solution Status
This issue has been fixed in the SerialLite II MegaCore function.
The Training Sequence Appears on the Atlantic Receive Interface
To request a relink, the far-end device sends a training pattern to the near-end device this training sequence may appear on the Atlantic receive interface.
Affected Configurations
This issue affects all variations of the MegaCore function.
Design Impact
Before one end of the link is brought down, a few cycles of meaningless data, including portions of the training sequence, may appear on the Atlantic interface.
Workaround
There is no workaround.
Solution Status
This issue has been fixed in the SerialLite II MegaCore function.

Quartus II Issues
This section describes the Quartus II issues.
The Quartus II Software Does Not Merge Transmit Phase-Lock Loops (PLLs) for Multiple Function Instantiations
The Quartus II software reports a no-fit for designs where more than one SerialLite MegaCore function is instantiated in each quad bank of serial inputs and outputs (I / Os). The Quartus II software consumes one ALTGXB transmitter PLL per instantiation, and does not merge the transmit PLLs even if the same reference clock is connected to each instantiation.
Affected Configurations
This issue affects single-lane and dual-lane variations that include more instantiations than the device ALTGXB transmitter PLLs.
Design Impact
Only a single instantiation can be used per quad bank of serial I / Os.
Workaround
The SerialLite top-level file can be modified to instantiate multiple SerialLite protocol core engines connected to a single ALTGXB transmitter PLL. The ALTGXB transmitter PLL can be configured to match the desired number of lanes. Each protocol core instantiation then connects to the associated bits on the ALTGXB transmitter PLL. Submit a mySupport request for help with this workaround.
Solution Status
This issue has been fixed in the Quartus II software version 5.1.
Demonstration Testbench
This section describes the testbench issues.
The Demonstration Testbench Fails in Unbalanced Configurations

3 SerialLite MegaCore Function v1.1.0 Errata Sheet
Contact Information
configurations (for example: CRC-32 payload protection for the transmitter, but no CRC payload protection for the receiver), the testbench fails.
Affected Configurations
This issue affects all variations of the MegaCore function.
Design Impact
The demonstration testbench reports an error, and indicates that the testbench has failed.
Workaround
No workaround is available for this issue. For unbalanced configurations, you must create an environment that uses two independent SerialLite MegaCore functions.
Solution Status
This issue has been fixed in the SerialLite II MegaCore function.
