Format for dumpfiles generated by EDA logic simulation tools
Value change dump (VCD) (also known less commonly as "variable change dump") is an ASCII-based format for dumpfiles generated by EDA logic simulation tools. The standard, four-value VCD format was defined along with the Verilog hardware description language by the IEEE Standard 1364-1995 in 1996. An extended VCD format defined six years later in the IEEE standard 1364-2001 supports the logging of signal strength and directionality. The simple and yet compact structure of the VCD format has allowed its use to become ubiquitous and to spread into non-Verilog tools such as the VHDL simulator GHDL and various kernel tracers. A limitation of the format is that it is unable to record the values that are stored in memories.
