READING VECTOR FILES
Most canned readers require very little information in the OVF_BLOCK of the vtran command file in order to read the vector data because most of these formats contain all necessary information. The following example illustrates the reading of vector data in WGL format:
ORIG_FILE = "apple.wgl";
TABULAR_FORMAT wgl –cycle, -scan;
. . .
In the next example, a Verilog VCD file is being read which, while it does contain the signal names, does not specify the directions of the signals and thus this information must be provided in the OVF_BLOCK:
ORIG_FILE = "maples.vcd";
Inputs barcode[31:0], redrum, shining;
Outputs yoj, evol, artam[12:0];
. . .
