METHOD AND SYSTEM FOR CONTROLLING CIRCUIT INPUT-OUTPUT TIMING |
摘要 |
An integrated circuit (IC) includes a plurality of input/output (I/O) terminals through which signals pass into or out of the IC and an I/O timing module. The I/O timing module is configured to add propagation delay to signals passing between the I/O terminals and I/O subsystems of the IC. The I/O timing module includes a plurality of delay elements associated with each of the I/O terminals, a control register associated with each of the I/O terminals, a memory, and I/O delay control logic. The control register is coupled to each of the delay elements associated with the I/O terminal. The memory is encoded with delay information. The I/O delay control logic is configured to initialize the propagation delay associated with each of the I/O terminals by selecting which of the delay elements are to be applied to produce the propagation delay based on the delay information stored in the memory. |
