NAME

6       vcd2lxt2 - Converts VCD files to LXT2 files

SYNTAX

9       vcd2lxt2 [option]... [VCDFILE] [LXTFILE]
10

DESCRIPTION

12       Converts VCD files to LXT2 files.
13

OPTIONS

15       -v,--vcdname <filename>
16              Specify VCD input filename.
17
18       -l,--lxtname <filename>
19              Specify LXT2 output filename.
20
21       -d,--depth <value>
22              Specify 0..9 gzip compression depth, default is 4.
23
24       -m,--maxgranule <value>
25              Specify number of granules per section, default is 8.  One gran‐
26              ule is equal to 32 timsteps.
27
28       -b,--break <value>
29              Specify break size (default = 0 = off).  When the break size  is
30              exceeded, the LXT2 dumper will dump all state information at the
31              next convenient granule plus dictionary boundary.
32
33       -p,--partialmode <mode>
34              Specify partial zip mode 0 = monolithic, 1 = separation.   Using
35              a  value of 1 expands LXT2 filesize but provides fast access for
36              very large traces.  Note that the default mode is neither  mono‐
37              lithic nor separation: partial zip is disabled.
38
39       -c,--checkpoint <mode>
40              Specify  checkpoint  mode.   0  is on which is default, and 1 is
41              off.  This is disabled when the break size is active.
42
43       -h,--help
44              Show help screen.

48       EXAMPLES
49
50       Note that you should specify  dumpfile.vcd  directly  or  use  "-"  for
51       stdin.
52
53       vcd2lxt dumpfile.vcd dumpfile.lxt --depth 9 --break 1073741824
54              This  sets the compression level to 9 and sets the break size to
55              1GB.
56
57       vcd2lxt dumpfile.vcd dumpfile.lxt --depth 9 --maxgranule 256
58              Allows more granules per section which allows for  greater  com‐
59              pression.
60

LIMITATIONS

62       vcd2lxt2  does  not store glitches as these are coalesced together into
63       one value change during the writing of the LXT2 file.
