Summarize the syntax of the digital test program in agilent3070.

Enter digital in the basic window and press F1 to enter the digital editing window. Press F1 again to return to the command state.

Enter:

Assign XX (name) to pins YY (pin definition, which assigns a name to the pin on IC)

Assign ZZ (name) to pins NN

.

Family LVT (what is the voltage to power up the IC, select the type of family in the board file)

Power XXX (define what the power pins are)

Inputs XX (define input pin)

Outputs XXX (define output pin)

Bidirectional XX (defines two-way pin)

Set load on groups XX to pull up (sets the initial state of the output pin or bi-directional pin to pull up)

Disable XXX with YY to "1" / "0" (XXX pin will not be available when YY pin is 0 or 1)

There are two methods for digital testing, which are pcf and vector testing

(1) pcf

To continue on the basis of the previous:

Pcf order is XXX, XX,X... (define the order of pcf tests)

Unit'test' (Test name)

Pcf

"00 HH" (based on the previous definition of the order of pcf, when pin1, input is 0, pin3 and pin4 output

For high. For more information, please see the datasheet of IC)

"11 HH" (ibid., write down all the tests of IC respectively)

.

End pcf

End unit

(2) vector

Vector test name (vector test name)

Drive AA (when it is a two-way pin, you need to distinguish when it is drive and when it is receive)

Receive BB

Set XXX to "1" (view the specific vector situation according to datasheet)

Set YYY to "1"

End vector (end vector definition)

. (multiple vectors can be defined as in the case of Amus00)

Unit "test" (start testing)

Execute Agg00 (executes a program with a vector name of Aq00)

Execute B_00

.

End unit (end test)
