GTKWave is a digital waveform viewer useful for examining the output of various digital simulators and an analysis tool used to perform debugging on Verilog or VHDL simulation models. With the exception of interactive VCD viewing, it is not intended to be run interactively with simulation, but instead relies on a post-mortem approach through the use of dumpfiles.
GTKWave as a collection of binaries is comprised of two interlocking tools: the gtkwave viewer application and rtlbrowse. In addition, a collection of helper applications are used to facilitate such tasks as file conversions and simulation data mining. The new release fixes some problems/bugs and adds new functions/features, e.g.;
- Disable accelerator keys in twinwave single window mode to avoid focus conflicts;
- Fixes for -fstrict-aliasing and other recent warnings;
- Added fill_waveform rc variable and corresponding menu option (/View/Show Filled High Values) to allow filling in the lower portion of high values for increased visibility.
