Trainer Script Enhancements

Teledyne LeCroy

When there are variable values in RawData, you must include SendCRC command instead

of last DWORD. Otherwise, wrong CRC value will be sent.

The constraints are:

 Variables are not allowed on First and LAST DWORD (instead of start/end

frames).

 SendCRC is only supported on last DWORD before end of frame.

SendSATAFrame

{

SATA_SOF

SATA_DATA ( 0x11223344 )

SATA_DATA (@variableName1)

SATA_DATA ( 0x55667788 )

#SATA_CRC ( 0x99AACCBB ) # good crc - can be changed to bad

SATA_EOF

}

If SATA_CRC command is not included, trainer engine computes and inserts correct CRC in

pattern.

5.13.6 Timer

Trainer script syntax allows using some timers. You can start a timer anywhere. The timer

current value is loadable on variable to be used in expressions and conditions on this

expression. There are four timers, named A, B, C, and D.

Startingtimer (setting timer value to zero) syntax is:

CLEAR_TIMER_A

CLEAR_TIMER_B

CLEAR_TIMER_C

CLEAR_TIMER_D

Loadingtimercurrentvalueinvariables:

@varName1 =TIMER_A

@varName1 =TIMER_B

@varName1 =TIMER_C

@varName1 =TIMER_D

Example:

CLEAR_TIMER_A

While(@Counter < MaxPeriodCount) {

… @Counter = TIMER_A … }

5.13.7 PATTERN Counter

Trainer script syntax allows you to use counters on a number of defined events in

generation settings.

Syntaxforloadingcountersinvariablesis:

@varName1 = COUNT_REC_RESOURCE_OUTPUT_A

@varName1 = COUNT_REC_RESOURCE_OUTPUT_B
