摘要
A prototype debugging system controlled by a host processor over a host bus includes: (a) a vector processor interface bus; (b) one or more programmable logic circuits, at least one of which provided to implement: (i) a logic circuit under verification; (ii) one or more programmable embedded debug circuits each receiving a first group of selected signals from the logic circuit under verification and providing control signals for (1) selecting a portion of the first group of selected signals, or (2) affecting the values of a second group of selected signals in the logic circuit under verification based on a portion of the first group of selected signals satisfying a predetermined triggering condition, wherein the programmable embedded debug circuits each including a built-in memory for storing signal vectors, the programmable embedded debug circuits each being configured according to a trigger specification defining one or more trigger states and triggering conditions; and (iii) a local debugging controller that controls programmable embedded debug circuits and transfers signal vectors between the built-in memories of the programmable embedded debug circuits and the vector processor interface bus; and (c) a vector processor which controls transferring of signal vectors between the host processor and the vector processor interface bus.
