Multiple clock domain debug capability |
摘要 |
An integrated circuit with debug capability includes a first packer and synchronizer to combine a multiple number of values of a first trigger signal received from a first circuit to form a first packed trigger signal and to output a synchronized first packed trigger signal in response to a trigger clock signal, the first trigger signal being synchronous with a first source clock signal, a first logic gate to provide a first output trigger signal indicative of whether any of the first multiple number of values of the first trigger signal in the first synchronized packed trigger signal is in a first state, and a debug state machine responsive to the first output trigger signal to selectively provide a first action signal. |

1. An integrated circuit with multiple clock domain debug capability comprising:
a first packer and synchronizer to combine a first plurality of values of a first trigger signal received from a first circuit to form a first packed trigger signal and to output a synchronized first packed trigger signal in response to a trigger clock signal, said first trigger signal being synchronous with a first source clock signal; a first logic gate to provide a first output trigger signal indicative of whether any of said first plurality of values of said first trigger signal in said first synchronized packed trigger signal is in a first state; and a debug state machine responsive to said first output trigger signal to selectively provide a first action signal. |
