[VCDFILE] [LXTFILE] DESCRIPTION Converts VCD files to LXT2 files. OPTIONS -v,--vcdname <filename> Specify VCD input filename. -l,--lxtname <filename> Specify LXT2 output filename. -d,--depth <value> Specify 0..9 gzip compression depth, default is 4. -m,--maxgranule <value> Specify number of granules per section, default is 8. One gran- ule is equal to 32 timsteps. -b,--break <value> Specify break size (default = 0 = off). When the break size is exceeded, the LXT2 dumper will dump all state information at the next convenient granule plus dictionary boundary. -p,--partialmode <mode> Specify partial zip mode 0 = monolithic, 1 = separation. Using a value of 1 expands LXT2 filesize but provides fast access for very large traces. Note that the default mode is neither mono- lithic nor separation: partial zip is disabled. -c,--checkpoint <mode> Specify checkpoint mode. 0 is on which is default, and 1 is off. This is disabled when the break size is active. -h,--help Show help screen. EXAMPLES Note that you should specify dumpfile.vcd directly or use "-" for stdin. vcd2lxt dumpfile.vcd dumpfile.lxt --depth 9 --break 1073741824 This sets the compression level to 9 and sets the break size to 1GB. vcd2lxt dumpfile.vcd dumpfile.lxt --depth 9 --maxgranule 256 Allows more granules per section which allows for greater com- pression. LIMITATIONS vcd2lxt2 does not store glitches as these are coalesced together into one value change during the writing of the LXT2 file.
