READING VECTOR FILES

Canned Readers- Examples:

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:

OVF_BLOCK

 BEGIN

 ORIG_FILE = "apple.wgl";

 TABULAR_FORMAT wgl –cycle, -scan;

 END;

PROC_BLOCK

  .  .  .

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:

OVF_BLOCK

 BEGIN

 ORIG_FILE = "maples.vcd";

 TABULAR_FORMAT verilog_vcd;

 Inputs barcode[31:0], redrum, shining;

 Outputs yoj, evol, artam[12:0];

 Bidirects level4[8:2];

 END;

PROC_BLOCK

 BEGIN

  .  .  .
