vcd2lxt - Converts VCD files to interlaced or linear LXT files
SYNTAX
vcd2lxt [VCDFILE] [LXTFILE] [option]...
DESCRIPTION
Converts VCD files to interlaced or linear LXT files. Noncompressed interlaced files will provide the fastest access, linear files will provide the slowest yet have the greatest compression ratios.
OPTIONS
-stats
Prints out statistics on all nets in VCD file in addition to performing the conversion.
-clockpack
Apply two-way subtraction algorithm in order to identify nets whose value changes by a constant XOR or whose value increases/decreases by a constant amount per constant unit of time. This option can reduce dumpfile size dramatically as value changes can be represented by an equation rather than explicitly as a triple of time, net, and value.
-chgpack
Emit data to file after being filtered through zlib (gzip).
-linear
Write out LXT in "linear" format with no backpointers. These are re-generated during initialization in gtkwave. Additionally, use libbz2 (bzip2) as the compression filter.
-dictpack <size>
Store value changes greater than or equal to size bits as an index into a dictionary. Experimentation shows that a value of 18 is optimal for most cases.
EXAMPLES
Note that you should specify dumpfile.vcd directly or use "-" for stdin.
