7
9 vcd2lxt2 [option]... [VCDFILE] [LXTFILE]
10
12 Converts VCD files to LXT2 files.
13
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
62 vcd2lxt2 does not store glitches as these are coalesced together into
63 one value change during the writing of the LXT2 file.
