GTKWave is VCD/EVCD/LXT/Synopsis .out format electronic waveform viewer built using the GTK+ toolkit. The project was originally developed by Tony Bybell but development has now passed to the APT group and we hope to extend and improve GTKWave to support new formats and features. Installation 1) Type ./configure 2) make 3) make install (as root) Make sure you copy the .gtkwaverc file to your home directory or to your VCD project directory. It contains the prefs for a good configuration that most people find ergonomic. Note that Ver Structural Verilog Compiler AET files are no longer supported. They have been superceded by LXT. Also note that the AMULET group will be taking over maintenance of the viewer effective immediately.
