| 5 | * Revision 1.1.1.1 2003/11/04 23:34:57 mjames |
||
| 6 | * Imported into local repositrory |
||
| 7 | * |
||
| 8 | * Revision 1.15 2003/01/02 21:37:16 mjames |
||
| 9 | * Experiment on creating NOT_ROUTABLE_H and NOT_ROUTABLE_L |
||
| 10 | * properties on the nets so that pin jumpers can be made without a problem. |
||
| 11 | * |
||
| 12 | * Still need to sort out pin assignments made to these not_routable nets |
||
| 13 | * which will become legal in some cases so that pullups and pulldown |
||
| 14 | * pins can be used on the FPGA. |
||
| 15 | * |
||
| 16 | * Revision 1.14 2002/09/30 13:20:29 MJAMES |
||
| 17 | * Modified partition rules to include 'default assignment on declaration' |
||
| 18 | * which maps to inputs being driven with default values on |
||
| 19 | * productuion of a partition. |
||
| 20 | * |
||
| 21 | * signal c : std_logic := '0'; |
||
| 22 | * |
||
| 23 | * becomes |
||
| 24 | * |
||
| 25 | * signal c: std_logic; |
||
| 26 | * |
||
| 27 | * begin |
||
| 28 | * c<= '0'; |
||
| 29 | * |
||
| 30 | * Revision 1.13 2002/09/18 08:51:24 mjames |
||
| 31 | * Removed unused variables |
||
| 32 | * |
||
| 33 | * Revision 1.12 2002/09/09 10:13:09 mjames |
||
| 34 | * Moved pin remapping function to pin ident editing function from |
||
| 35 | * sorting pin name routine. |
||
| 36 | * |
||
| 37 | * Revision 1.11 2002/01/16 11:22:47 mjames |
||
| 38 | * database.h header file is read in first as it undefined DLL stuff irrelevant |
||
| 39 | * to HPUX |
||
| 40 | * |
||
| 41 | * Revision 1.10 2001/12/13 22:17:28 mjames |
||
| 42 | * Using #ident with header to identify file |
||
| 43 | * |
||
| 44 | * removed debug messages |
||
| 45 | * |
||
| 46 | * Revision 1.9 2001/10/31 22:20:11 mjames |
||
| 47 | * Tidying up problematical comments caused by CVS |
||
| 48 | * 'intelligent' comment guessing |
||
| 49 | * |
||
| 50 | * Revision 1.8 2001/10/31 16:21:46 mjames |
||
| 51 | * Added a datastructure to hide regular expression information from programs. |
||
| 52 | * Changed call to regexec to indicate 0 subexpressions to be matched |
||
| 53 | * rather than a number dependent on strlen(string) which was wrong. |
||
| 54 | * Altered diagnostics while debugging checked in because useful at other |
||
| 55 | * times |
||
| 56 | * |
||
| 57 | * Revision 1.7 2001/10/10 20:18:23 mjames |
||
| 58 | * Added a vert_regcomp function to compile regular expressions |
||
| 59 | * with '^' (match start string) and '$' (match end string) bracketing |
||
| 60 | * this => wildcard must match entire string not just a part of it. |
||
| 61 | * |
||
| 62 | * Revision 1.6 2001/10/07 20:50:53 mjames |
||
| 63 | * Added wildcard checking (warn user about |
||
| 64 | * using wildcard '*' on the end of a string in stead of wildcard '.*') |
||
| 65 | * |
||
| 66 | * Revision 1.5 2001/09/25 23:24:18 mjames |
||
| 67 | * Update because wildcard behaviour amended |
||
| 68 | * |
||
| 69 | * Revision 1.4 2001/08/01 07:38:03 mjames |
||
| 70 | * Removed multiple informational messages |
||
| 71 | * replaced with summary unless debug level is higher |
||
| 72 | * |
||
| 73 | * Revision 1.3 2001/06/06 12:10:19 mjames |
