HS_VS_MI

SYNTAX:

HS_VS_MI(VS_NO [, UP_LIMIT=x] [, DOWN_LIMIT=x] [, MEAS_LOOP=x] [, AVG or MAX or MIN or MAVG] [, CLEAR_CONT/CONT_NEXT/PTN_FORCE_STOP/PATTERN_END] [, LOG_OFF] [, MEASURE_LOOP_INTERVAL=x] [, BinNo=x] [, LOG_ALIAS=name] [, LOG_UNIT=unit] [, LOG_SITE=x] [, USER_MONITOR/USER_MON_ONLY] [, IGNORE_FAIL] [, DIGITAL_FILTER=0~6] [, C_LOAD_OFFSET_BASE=B3/B1/B1_ACTIVE_LOAD] [, LCD_PIN=PinGroup] [, ADC_SWITCH_WAIT=x]);

NOTE: The argument which can use _C_Variable (VS_NO [, UP_LIMIT=x] [, DOWN_LIMIT=x] [, MEAS_LOOP=x])

DESCRIPTION:

Read back the resource measure value that connect to ADC in tester. HS_VS_MI including the measure of result and check the pass range for this result.

NOTE:

Before executing any measure command, user must execute force command first. Otherwise, system will follow the initial state.

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: UP_LIMIT=x

x : a current value, Unit: A, mA, nA or parameter name or GB1~64/MEASURE_VALUE/PinName variable or _C_Variable(double).

PARA: DOWN_LIMIT=x

x : a current value, Unit: A, mA, nA or parameter name or GB1~64/MEASURE_VALUE/PinName variable or _C_Variable(double).

PARA: MEAS_LOOP=x

Measure for x times to get the Average, Minimum, Maximum value.

Range:1-4096 or _C_Variable

Default: 1

PARA: AVG or MAX or MIN or MAVG

AVG/MAX/MIN/MAVG

AVG: Use the Average value to compare limit.

MAX: Use the Maximum value to compare limit.

MIN: Use the Minimum value to compare limit.

MAVG: get all measure values, ranking, then remove least 25% and largest 25% of measure values, average middle 50% of measure values. In this mode MEAS_LOOP range in 3~512, and take longer measure time

Default: AVG.

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: MEASURE_LOOP_INTERVAL=x

sampling time between each measure execution in measure loop

Resolution: 55ns

Range:5.1us ~ 3.281ms

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 measure result, and go to next driver.

Default: OFF.

PARA: DIGITAL_FILTER=0~6

0: 200kHz

1: 100kHz

2: 50kHz

3: 25kHz

4: 12.5kHz

5: 6.25 kHz

6: 3.125kHz

PARA: C_LOAD_OFFSET_BASE=B3/B1/B1_ACTIVE_LOAD

C_LOAD Compensation for B3/B1/B1_ACTIVE_LOAD.

PARA: LCD_PIN=PinGroup

Select LCD_PIN for C_LOAD_OFFSET_BASE.

PARA: ADC_SWITCH_WAIT=x

Wait time of ADC_SWITCH for C_LOAD_OFFSET_BASE.

x range:10us-200s or parameter name; Unit: s or ms or us;

Default: 10ms, Resolution: 10us.

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_MI(HS_VS9, UP_LIMIT=2.0UA, DOWN_LIMIT=-2.0UA);

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

WAIT(1MS);

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

WAIT(1MS);
