General Commands

LASER_ON

Enables exerciser to send traffic without the Link-Up process.

LINK_RESET_PROT

BE initiates link reset protocol sequence

LINK_FAILURE_PROT

BE initiates link Failure protocol sequence

EXIT_MANUAL_TRAINING

When a manual training frame command Is used, Exerciser moves to a state where it continuously sends Training frames until this command is executed.

Example

When a wait command is written after a SendTrainingFrame command, the Exerciser keeps sending the last training frame instead of idles. This command is used to exit from manual training command and move on to normal data.

Send_NOS

Exerciser sends NOS for the time specified in NOS_Transmit_time speed neg settings.

Send_OLS

Exerciser sends OLS for the time specified in OLS_Transmit_time speed neg settings.

Send_LR

Exerciser sends LR for the time specified in LR_Transmit_time speed neg settings.

Send_LRR

Exerciser sends LRR for the time specified in LRR_Transmit_Time speed neg settings.

SendTrainingFrame

Transmits a specific Training Frame.

SendRawTrainingFrame

Transmits user specified 32+256 bits of Manchester encoded data.

SendAlignmentMarkerError

Indicates which index of Alignment Marker (AM) to be corrupted.(ex: 64G FC has 4 AMs. Each index0-3 indicates 4 AMs respectively).

Format

SendAlignmentMarkerError(Index_Mask, Replace Index Mask, Count)

where:

  • Index_Mask (Index_0..index_3): Indicates which index of AM to be corrupted (e.g., 64G FC has 4 AMs. Each index0-3 indicates 4 AMs, respectively).

  • Replace Index Mask (0-3) with User-defined value: When this bit is set User defined value specified in speed neg settings will be Placed in the corresponding Alignment marker for no. of times specified in count.

  • Count: Number of AMs to be corrupted.

Example

SendAlignmentMarkerError (INDEX_0 | INDEX_1 | INDEX_2, REPLACE_INDEX_1 | REPLACE_INDEX_2, 1024)

SetAMIndexValue

Sets alignment marker default values for Index0..Index3. These values can be used later in the SendAlignmentMarkerError command to inject alignment marker error.

Speed Negotiation Settings

Command

Value

Description

AM_Remote_Degrade

OFF

When this bit set to high, Remote Degrade bit for Alignment marker is calculated according to the degrade counters specified inside Speed Neg parameter block—When disabled Zero is placed in RD bit of AM.

FEC_Degrade_interval

0

This is a 32 bit register that specifies the number of RS-FEC code words that make up a Degrade interval.

Degrade_Activate_threshold

0

This is a 32 bit register that specifies a symbol error count. If error count is more than this value, then RD bit gets high.

Degrade_Deactivate_Threshold

0

This is a 32 bit register that specifies a symbol error count. The value here controls the threshold used to deactivate RD.

NOTE: The Reed Solomon Decoder counts the number of symbol errors detected in all the code words within the FEC_Degrade_interval. If a codeword is uncorrectable, the number of symbol errors detected is incremented by 16. When the number of symbol errors detected within a FEC_Degrade_interval exceeds the Degrade_Activate_Threshold, RD will be signaled to the remote link partner using a bit in the Alignment Marker. At the end of an interval, if the number of symbol errors is less than the Degrade_Activate_Threshold, RD will be signaled to the remote link partner using a bit in the Alignment Marker. At the end of an interval, if the number of symbol errors is less than the Degrade_Deactivate_Threshold, RD will be de-asserted in the Alignment Marker.

Predefined Ordered Sets

The following ordered sets are defined by default in the FC Exerciser. They can be used inside SendData, SendFrame and Frame commands.

  • Idle

  • LPI

  • SOFi2

  • SOFn2

  • SOFi3

  • SOFn3

  • SOFf

  • EOFt

  • EOFa

  • EOFn

  • EOFni

  • R_RDY

  • VC_RDY(a, b)

  • BB_SCs

  • BB_SCr

  • NOS

  • OLS

  • LR

  • LRR

Note: VC_RDY parameters are optional and can be numbers, constants or variables. When using VC_RDY with no parameters, a and b are assumed to be zero.

Wait/Wait For Commands

After using Wait/Wait_for commands, the exerciser will wait until the specified timeout has elapsed (default value if not specified) or any of the defined conditions are satisfied e.g. SOF ordered set is received from the DUT.

Syntax

WAIT_FOR { <command1> <command2> ... <group1> <group2> ... }

Possible conditions for wait and wait_for commands:

Wait Command Name

Description

WF_TIMEOUT

Timeout Credit Available

When WF_TIMEOUT is requested in WAIT_FOR command, the wait session will be released after timeout has elapsed.

See WHEN / ELSEWHEN / ON_TIMEOUT Commands for more detailed explanation.

The Timeout value can be set two different ways:

  1. Through the global WaitTimeout setting that can appear anywhere in generation. Default value is 1000 microseconds. Syntax: Set WaitTimeout = <value> (in microseconds)

  2. Through local WaitTimeout value for this specific wait session. Syntax: WAIT_FOR (<number_of_microseconds>){WF_TIMEOUT

<other_wait_commands>}

In this case wait for other commands will be released no later than after number_of_microseconds, but global WaitTimeout value remains unchanged for future use.

WHEN / ELSEWHEN / ON_TIMEOUT Commands

The “on_timeout” command is related to the “wait-condition” command. The user can specify the statements that have to happen when the time (which is mentioned in the “wait-condition”) elapses (without any of the “when” statement taking place). Typical syntax would be:

wait (time)
{
  When {exp} do
  {
    #Some statements
  }
  elsewhen {exp} do
  {
    #Some statements
  }
  on_timeout
  {
    #Some statements, which would get executed when timeout happens (“time”)
  }
}

WF_TIMEOUT Parameter

WF_TIMEOUT is a parameter within “wait_for” command. When the user specifies it in the “wait_for” command, the wait session will be released after the timeout has elapsed. Typical syntax would be as follows:

wait_for (time) { WF_R_RDY WF_TIMEOUT }

Note that “wait_for” command can be also defined without mentioning time-out as well. Following is an example for it:

wait_for {WF_OLS}

In this case, the Exerciser waits indefinitely for the WF_OLS parameter to become true. If the user doesn’t want to get blocked indefinitely, the WF_TIMEOUT parameter can be used.

Predefined Constants

Predefined Constant

  • TRUE

  • FALSE

  • ON

  • OFF

  • INFINITE

TRUE or ON values are equal to 1 and FALSE or OFF values are equal to 0. INFINITE constant is only used in the infinite loop expressions.

Loop (INFINITE) { … }

Generation Settings

To change the default values of FC exerciser settings you can use SET command before and inside Generation block. If a setting value is updated outside Generation block multiple files (e.g. in different header files) the latest value would be used and applied only once to the Exerciser but inside Generation block, all the set commands would be applied, even if they are used back to back.

Set setting_name = setting_value

All the generation settings are applied before Generation block with their default values unless they are defined by the user or inside the “Settings.inc” in case it’s included in the script.

The following settings are only valid before Generation block:

  • GenerationMode

  • AutoConnect

  • AutoReconnect

OFF

When this bit is set, exerciser inserts fill words specified in IPG_count automatically after each frame.

Possible Values: ON/OFF

When AutoFillWordInsertion is ON, This would be the number of fill Dword inserted after each frame.

FC 16G FEC Setting
