vzt2vcd(1)

vzt2vcd1

Converts vzt files to vcd

Usage

vzt2vcd [option] ... [VZTFILE]

Overview

Converts VZT files to VCD files. If an output filename is not specified, the VCD is emitted to stdout.

Options

-v,--vztname <filename>

Specify VZT input filename.

-o,--output <filename>

Specify optional VCD output filename.

-f,--flatearth

Emit flattened hierarchies.

-c,--coalesce

Coalesce bitblasted vectors.

-n,--notruncate

Do not shorten bitvectors. This disables binary value compression as described in the IEEE-1364 specification. (i.e., all values except for '1' left propagate as a sign bit on vectors which do not fill up their entire declared width)

-h,--help

Display help then exit.

Examples

To run this program the standard way type:

vzt2vcd filename.vzt

The VCD conversion is emitted to stdout.

Limitations

vzt2vcd does not re-create glitches as these are coalesced together into one value change during the writing of the VZT file.
