A register transfer level (RTL) IC design describing a IC as comprising a plurality of logic blocks communicating via signals and using a high level language to describe the logic blocks according to the logical relationships between signals they receive and signals they generate. A computer-aided synthesizer processes an RTL IC design to produce a gate level design for the IC describing its logic blocks as comprising instances of cells communicating via signals. A synthesizer or emulator processes the gate level design to produce a gate level dump file referencing signals of the gate level design and indicating how those signals behave in response to time-varying signals supplied as inputs to the IC. The gate level dump file is converted into an RTL dump file referencing signals of the RTL design and indicating how those signals behave. A debugger processes the RTL dump file to produce displays depicting the RTL design and behavior of signals indicated by the RTL dump file. Thus while the IC is simulated or emulated at the gate level of the design to produce waveform data for a debugger, the gate level-to-RTL dump file conversion process enables a designer debug the more familiar RTL design based on the gate level simulation or emulation results.
