| Description |
$reset and $save $restart are all optional informative tasks described in annex C, however the VPI related callbacks and control constant vpiReset are normative. I suggest that we describe the behaviour of the VPI related features dependent on the support of the optional functionality from the simulator. |
| Fix |
Proposal is: in section 27.3 (vpi_control) to replace: vpiReset causes the $reset built-in Verilog system task to be executed upon return of the user function. with: vpiReset if $reset is supported by the tool, causes the $reset built-in Verilog system task to be executed upon return of the user function, otherwise it has no effect. Additionally in section 27.33.3: Create a new category of optional callbacks which would contain the save, restart and reset callbacks. Proposal: Replace: Examples of possible feature related callbacks are cbStartOfSave Simulation save state command invoked cbEndOfSave Simulation save state command completed cbStartOfRestart Simulation restart from saved state command invoked cbEndOfRestart Simulation restart command completed cbEnterInteractive Simulation entering interactive debug mode (e.g., $stop system task executed) cbExitInteractive Simulation exiting interactive mode cbInteractiveScopeChange Simulation command to change interactive scope executed cbUnresolvedSystf Unknown user-defined system task or function encountered With: List of standard feature related callbacks: cbEnterInteractive Simulation entering interactive debug mode (e.g., $stop system task executed) cbExitInteractive Simulation exiting interactive mode cbInteractiveScopeChange Simulation command to change interactive scope executed cbUnresolvedSystf Unknown user-defined system task or function encountered List of optional feature related callbacks (note the support of the following callbacks is dependent on the support of the feature by the tool) cbStartOfSave Simulation save state command invoked (e.g $save, $incsave system task invoked) cbEndOfSave Simulation save state command completed cbStartOfRestart Simulation restart from saved state command invoked (e.g $restart system task invoked) cbEndOfRestart Simulation restart command completed cbStartOfReset Simulation reset to time 0 command invoked(e.g $reset system task executed) cbEndOfReset Simulation reset to time 0 completed |
