HS_VS_CLAMP

SYNTAX:

HS_VS_CLAMP_DETECT(VS_NO [, MARK_NO=x] [, CLEAR_CONT/CONT_NEXT/PTN_FORCE_STOP/PATTERN_END] [, LOG_OFF] [, BinNo=x] [, LOG_ALIAS=name] [, LOG_UNIT=unit] [, LOG_SITE=x] [, USER_MONITOR/USER_MON_ONLY] [, IGNORE_FAIL]);

DESCRIPTION:

Detect VS clamp status and return value on datalog. User can utilize "MARK_NO" to control the test flow.

Return 0: Until currently clamp detect instruction, selected VS didn't occur clamp.

Return 1: Until currently clamp detect instruction, selected VS had occurred clamp or occurring clamp now.

NOTE: After clamp detection, the clamp detect value won't be returned to zero by system. User must set "HS_CLEAR_CLAMP_DETECT" to clear the clamp detect value of all HS resources. After that, clamp detect value will be returned to zero.

REQUIRED ARGUMENT:

PARA1: VS_NO

HS_VS9~32 or power_source_name(string) that has been defined in the PRJ file. Or _C_Variable

OPTIONAL ARGUMENT:

PARA: MARK_NO=x

When selected VS occurred clamp, MARK_NO will be set.

x: a integer from 1 to 199

PARA: CLEAR_CONT/CONT_NEXT/PTN_FORCE_STOP/PATTERN_END:

CLEAR_CONT: clear the continued running of pattern. Then, pattern and main program will go on simultaneously.

CONT_NEXT: clear the continued running of pattern and wait for pattern executing to the next MI "CONT" vector or pattern end.

Then, main program will go on.

PTN_FORCE_STOP: doesn't clear the continued running of pattern but break the running pattern forcibly.

PATTERN_END: clear the continued running of pattern and wait for executing to the pattern end. Then, main program will go on.

Default: NONE

PARA: LOG_OFF

Set measured value not log to datalog windows, even it is set to be on in engineering set.

Default: Depend on engineering setting.

PARA: BinNo=x

x: a integer from 1 to 2048; While test result is fail at this driver, system classify the device to bin x.

PARA: LOG_ALIAS=name

name: a string; EX: LOG_ALIAS=ABC. The setting name will show in the .csv file and user monitor.

PARA: LOG_UNIT=unit

unit: a string; EX: V, mV ......., This setting will show after the alias name.

Parameter can be set to LOG_UNIT=unit[.X] , this function can set the significant digits of fractional portion which will be shown in the .csv file.

X: The number of significant digits of fractional portion.

PARA: LOG_SITE=x

x: site number from 1 to 64. User set the site number that needed to log to file or user monitor. EX: LOG_SITE=[1,3-5,8],

Default: Log all site.

PARA: USER_MONITOR/USER_MON_ONLY

USER_MONITOR: Log measured value to user monitor.

USER_MON_ONLY: Only show measured value in monitor without producing C.S.V file and STDF file.

PARA: IGNORE_FAIL

This argument is identical to the function "Dc Ignore Fail=On" on engineer setting menu. It ignore the detect result, and go to next driver.

Default: OFF.

EXAMPLE:

HS_FORCE_VS(HS_VS9, FORCE_V, 0.0V, 40UA, E1, I2);

WAIT(1MS);

HS_CLOSE_VS_OUTPUT_RELAY(HS_VS9, WAIT=3mS, ON);

WAIT(1MS);

HS_FORCE_VS(HS_VS9, FORCE_V, 3.0V, 40UA, E1, I2);

WAIT(1MS);

HS_VS_CLAMP_DETECT(HS_VS9, MARK_NO=10); //When selected VS occurred clamp, MARK_NO set to be 10.
