Structure/Syntax
The VCD file comprises a header section with date, simulator, and timescale information; a variable definition section; and a value change section, in that order. The sections are not explicitly delineated within the file, but are identified by the inclusion of keywords belonging to each respective section.
VCD keywords are marked by a leading $ (but variable identifiers can also start with a $). In general every keyword starts a section which is terminated by an $end keyword.
All VCD tokens are delineated by whitespace. Data in the VCD file is case sensitive.

Famous quotes containing the word structure:
“Vashtar: So it’s finished. A structure to house one man and the greatest treasure of all time.
Senta: And a structure that will last for all time.
Vashtar: Only history will tell that.
Senta: Sire, will he not be remembered?
Vashtar: Yes, he’ll be remembered. The pyramid’ll keep his memory alive. In that he built better than he knew.”
—William Faulkner (1897–1962)
