||
4 | * Revision 1.1.1.1 2003/11/04 23:34:57 mjames |
||
5 | * Imported into local repositrory |
||
6 | * |
||
7 | * Revision 1.14 2002/10/02 18:39:54 MJAMES |
||
8 | * Stopped copying pin_col to index on every node |
||
9 | * |
||
10 | * Revision 1.13 2002/09/16 14:41:43 mjames |
||
11 | * Merge back pin indexing bug that meant |
||
12 | * pin AZ12 was indistinguishable from pin Z12 in |
||
13 | * rename ident/name commands |
||
14 | * |
||
15 | * Revision 1.12 2002/09/09 10:10:21 mjames |
||
16 | * Moved pin remapping function to pin ident editing function from |
||
17 | * sorting pin name routine. |
||
18 | * |
||
19 | * Revision 1.11 2002/09/09 09:53:01 mjames |
||
20 | * Moved pin remapping function to pin ident editing function from |
||
21 | * sorting pin name routine. |
||
22 | * |
||
23 | * Revision 1.10 2002/08/23 14:13:55 mjames |
||
24 | * Added legal/illegal pin identifying letters to the header file. |
||
25 | * Upgraded sort to determine row/column locations of pins identified like |
||
26 | * 'a1' and '1a' etc or '1' , '2' |
||
27 | * |
||
28 | * Revision 1.9 2001/10/31 22:33:27 mjames |
||
29 | * Suppress diagnostic print |
||
30 | * |
||
31 | * Revision 1.8 2001/10/31 22:20:17 mjames |
||
32 | * Tidying up problematical comments caused by CVS |
||
33 | * 'intelligent' comment guessing |
||
34 | * |
||
35 | * Revision 1.7 2001/10/31 16:15:36 mjames |
||
36 | * Added a datastructure to hide regular expression information from programs. |
||
37 | * |
||
38 | * Revision 1.6 2001/10/22 10:53:50 mjames |
||
39 | * Added a declaration of the Vertical regular expression compiler |
||
40 | * which validates and complains about older 'regular expressions' |
||
41 | * used by Vertical prior to using regexp in the C library |
||
42 | * |
||
43 | * Revision 1.5 2001/10/10 20:17:59 mjames |
||
44 | * Added a vert_regcomp function to compile regular expressions |
||
45 | * with '^' (match start string) and '$' (match end string) bracketing |
||
46 | * this => wildcard must match entire string not just a part of it. |
||
47 | * |
||
48 | * Revision 1.4 2001/09/16 20:36:03 mjames |
||
49 | * Second attempt to modify wire bundles to be connector rather than net |
||
50 | * centric. Allows more than one connector to carry the same net, |
||
51 | * |
||
52 | * Revision 1.3 2001/09/16 19:48:53 mjames |
||
53 | * Modified sorting algorithm to have sideffect of calculating pin rows and |
||
54 | * columns for sockets. |
||
55 | * |
||
56 | * Revision 1.2 2001/06/06 12:10:17 mjames |
