Abstract

A method and apparatus is provided to debug using replicated logic. A text representation of a circuit is compiled to generate a first register transfer level (RTL) netlist. The netlist may be mapped to a target architecture, such as a field programmable gate array (FPGA). The netlist may be used to program an FPGA to create a prototype board for debugging. After debug, a portion of the circuit that a designer would like to analyze is selected. The selected portion of the circuit is replicated. Delay logic is inserted to delay the inputs into the replicated portion of the circuit. The text representation of the circuit is recompiled to generate a second RTL netlist. The second RTL netlist may be mapped to a target architecture, such as a FPGA or application specific integrated circuit (ASIC).
