Abstract: Systems, methods, and products having pipelined inputs to and outputs from an emulator are disclosed. Using a pipeline may allow the round trip cable delay (RTCD) to be spread across two or more clock cycles. In an embodiment, an emulation system may store input data received from a target device during a first clock cycle at a target timing domain interfacing component (TTD), and transmit the stored input data during a second clock cycle after the first clock cycle. In another embodiment, the emulation system may delay transmitting the input data received at the TTD during the first clock cycle such that that the input data reaches the emulator at a predetermined time during the second clock cycle. As the RTCD is spread across multiple clock cycles, the emulation system may implement faster clocks.

Abstract: A method and system for dynamically injecting errors to a user design is disclosed. In one embodiment, the user design having internal states and parameters is run in a design verification system. A reconfigurable design monitor monitors a plurality of error conditions based on the internal states and parameters of the user design and generates a trigger event when a predefined error condition is met. The reconfigurable design monitor transmits a trigger event to an error injector. The error injector injects dynamic errors associated with the triggering event to the user design via a control path to test the user design under the predefined error condition.
