Control Interface Programming Example
The following conservative pattern connects all outputs to input number 7, except output 16 which is connected to input number 32.
The vector clock period, T
0
is 15 ns. It is possible to accelerate the execution of this pattern by deleting vectors 1, 4, 7, and 9.
