Description

VCD2FST

NAME

vcd2fst - Converts VCD files to FST files

SYNTAX

vcd2fst [option]... [VCDFILE] [FSTFILE]

DESCRIPTION

Converts VCD files to FST files.

OPTIONS

-v,--vcdname <filename>

Specify VCD/FSDB/VPD/WLF input filename. Processing of filetypes other than VCD requires that the appropriate 2vcd converter was found during ./configure.

-f,--fstname <filename>

Specify FST output filename.

-4,--fourpack

Indicates that LZ4 should be used for value change data (default).

-F,--fastpack

Indicates that fastlz should be used instead of LZ4 for value change data.

-Z,--zlibpack

Indicates that zlib should be used instead of LZ4 for value change data.

-c,--compress

Indicates that the entire file should be run through gzip on close. This results in much smaller files at the expense of a one-time decompression penalty on file open during reads.

-p,--parallel

Indicates that parallel mode should be enabled. This spawns a worker thread to continue with FST block processing while conversion continues on the main thread for new FST block data.

-h,--help

Show help screen.

EXAMPLES

Note that you should specify dumpfile.vcd directly or use "-" for stdin.
vcd2fst dumpfile.vcd dumpfile.fst --compress

This indicates that the FST file should be post-compressed on close.
