LCD_MV

SYNTAX:

LCD_MV(PINS [, UP_LIMIT=x] [, DOWN_LIMIT=x] [, MEAS_LOOP=x] [, AVG or MAX or MIN or MAVG or RAM] [, RESULT=name] [, PIN_INC/STEP_INC] [, LOG_OFF] [, BinNo=x] [, LOG_ALIAS=name] [, LOG_UNIT=unit] [, USER_MONITOR] [, IGNORE_FAIL] [,MEASURE_LOOP_INTERVAL=x] [,RESULT=x]);

DESCRIPTION:

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

REQUIRED ARGUMENT:

PARA1: PINS

PIN_GROUP_NAME or PIN_NAME

OPTIONAL ARGUMENT:

PARA: UP_LIMIT=x

x : a voltage value, unit: V, mV or parameter name or GB1~64/MEASURE_VALUE/PinName variable or _C_Variable(double).

PARA: DOWN_LIMIT=x

x : a voltage value, unit: V, mV 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:64K - 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 3~30000,and take longer measure time

Default: AVG.

PARA: RESULT=name

RESULT: array name

System buffer name and file name saved the log data. Log data also saved in global array Sys_SW_BUFFER_DATA[][].

If there are more than two "LCD_MV" driver in a prg file, it must set in different name to avoid system conflict.

PARA: PIN_INC/STEP_INC

Set the data mode.

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: USER_MONITOR

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: MEASURE_LOOP_INTERVAL=x

sampling time between each measure execution in measure loop

Range:6uS-106uS

default: 6uS

PARA: RESULT=name

RESULT: array name

Array saved the log data.

EXAMPLE:

ARRAY<double> AAAAA(800*2);

LCD_SET_ADC_SWITCH_TABLE(LCDPIN);

LCD_SET_SWITCH(ADC=ON, RVS=OFF, ACTIVE_LOAD=OFF,WAIT=0mS);

WAIT(3mS);

LCD_MV(LCDPIN,RESULT=AAAAA);

for(int site=0;site<Sys_TEST_DIE;site++){

for(int i=0;i<800;i++){

GBX[i+1024*site]=AAAAA[i+800*site];

}

C_COMPARE(GBX1 , UP_LIMIT=-3, DOWN_LIMIT=-4);

C_COMPARE(GBX500 , UP_LIMIT=-3, DOWN_LIMIT=-4);

C_COMPARE(GBX800 , UP_LIMIT=-3, DOWN_LIMIT=-4);
