ABSTRACT:
Some embodiments provide a configurable integrated circuit (IC) comprising multiple deskew circuits for delaying data passage. Each of the deskew circuits comprises a stepwise delay circuit with multiple outputs and an input selection circuit with multiple inputs. Multiple outputs connect to multiple inputs. In some embodiments the configurable IC is a subcycle reconfigurable IC. In some such embodiments each of the deskew circuits further includes a space-time load control circuit for commanding the stepwise delay circuit to load during a selected subcycle. In some embodiments the multiple deskew circuits send data to trigger circuit. In some such embodiments the trigger circuit triggers a trace buffer to stop recording a data stream. In some such embodiments the trigger circuit triggers the trace buffer to stop after a programmable delay.
