Capture
Capture On
Capture Off
The Capture phrase causes the input section to be clocked
on the opposing edge of the selected output clock (which
causes the clocking to occur near the center of the
preceding vector). Only one capture should be used for a
single data field (i.e., you can place two capture statements
in a row, but only one will be performed). The Capture
On/Capture Off pair can be placed in a file where clocking
the input section for all data fields contained between
Capture On and Capture Off is required. If INTFREQ, INT,
or POD are the selected clocks, an input capture is
guaranteed. If DRCLK is selected, the clock supplied by
the user must have an opposing edge to assure that an input
capture occurs.
Wait <x>
The Wait phrase pauses vector driving until the appropriate
rising or falling edge is detected on the Vector Output I/O
Module WAIT line before vector driving continues. <x>
may be specified as + for rising edges and - for falling
edges. <x> can only be set to one edge type in a vector file.
If more than one edge type is specified in the file, an error
message is generated.
If the vector file contains a loop/endloop pair and you start driv-
ing vectors from a data field within that loop using the TL/1
vectordrive command, vectors are driven until the count reaches
the endloop statement, and then starts the loop again on the vec-
tor just after the loop command. For example, if your vector file
looks like:
GROUPS [40-1]
DISPLAY BIN
TIME DATA
1 1111111000111110000000000000111010001110
