| Description |
This came up in discussion of priorities group. It is useful to be able to change the default initialization of variables from X to 0 or to 1 or to a random value. Some studies suggest that it improves detection of bugs due to uninitialized or wrongly reset signals. We discussed a new idea of compiler directives for initialization of variables to 0 or 1 or random. Some tools do this today by a command-line switch. Both methods have advantages and disadvantages. An advantage of compiler directives is that they can be selective, i.e., on part of the design. A disadvantage is that it involves touching the design files. We recommend this for further consideration with priority MEDIUM. |
