/*Channels can operate in two modes. Static or dynamic.Static mode is sort of like have a register control the drive and expect states of a channel.
|
|
You load the register with the logic 1 or 0 that you want to drive or detect and then this is applied by to the UUT all at one time.
|
|
The 1 / 0 values are used to determine the high / low(VIH / VIL) from the drive side or the high / low expected(VOH / VOL) from the detector.
|
|
The channel is bidirectional.The various pin opcodes determine the whether you want to drive or detect or both.
|
|
IH or IL is drive only the detect is a don't care. OH or OL is detect only the drive is off. MH or ML is both drive and detect.
|
|
This later opcode is called monitor high/low. You might use this if you want to Monitor the drive to verify the signal is being output to the UUT.
|
|
In dynamic mode, the pin opcodes are loaded into a memory, the pattern memory, behind each channel. This is the dynamic pattern loading process.
|
|
A pattern controller is used to sequence the patterns out of the pattern memory and it has a instruction memory that is used to control this sequence of this pin opcodes
|
|
from the pattern memory.You can sequence patterns one after the other, repeat a pattern memory location several times, repeat a sequence of pattern memory locations
|
|
multiple times.The repeating pattern locations can be controlled by a count or a condition of the PASS/ FAIL test result of a pattern.The pattern controller also controls
|
|
whether a test should be associated with a pattern memory location. The are also pattern controller instruction halt that defines the last pattern of a sequence.
|
|
In dynamic mode you also have a timing sets that define the pattern time, when a channel will assert a high or low in that pattern time or when to observe the
|
|
detector in the pattern time.There is a memory for holding this information as well so that you can have different timing from one pattern to another.
|
|
After the memories have been loaded, operation of the pattern sequence is turned over to the pattern controller to run.
|
|
This starts applying the patterns under the pattern controller sequence instructions until a halt instruction is executed where it returns control back to the driver.
|
|
This is called dynamic pattern set execution or a dynamic burst.During the burst, another memory element is used to capture and record the pattern to pattern
|
|
pass fail information as well as what pin have failed.There are API functions to retrieve this information.*/
