Abstract
An apparatus for generating a digital signal pattern may comprises a memory, a program sequencer, first and second circuits, and an event execution unit. The memory may have stored therein a plurality of instructions that, when executed, cause a digital signal pattern to be generated on a plurality of nodes. The program sequencer may be configured to control a sequence in which the plurality of instructions are retrieved from the memory and executed. The first circuit may sequentially step through a plurality of different output states in response to a clock signal. The second circuit may identify an output event when an output state of the first circuit corresponds to an output state identified by retrieved instructions of a particular type. The event execution unit may control states of signals on the plurality of nodes in a manner specified by the retrieved instructions of the particular type in response to the second circuit identifying an output event.
