Simulation and debugging
Breakpoints in processes, simulation-time control, time travel, and the signal viewer.
HDL Studio drives GHDL through a small VPI agent and, for source-level debugging, through GDB. The result is one debug session that understands both kinds of stepping: through sequential statements, and through simulated time.
The debuggerBreakpoints, stepping, simulation-time control, data breakpoints, assertions and the Debug Console.
Time travelStep back, reverse continue and Run Back To: rewinding a debug session in simulated time.
The signal viewerLive, GPU-drawn waveforms of the running simulation: navigation, cursors, radixes, analog traces and deposits.
Waveform filesOpen GHW and VCD files in the signal viewer, and choose which format to record.
