Support for the vpi_register_systf Routine

VCS supports the vpi_register_systf VPI access routine. To use it you

need to make an entry in the vpi_user.c file. You can copy this file

from $VCS_HOME/etc/vpi. The following is an example:

In this example:

• The routine named register_me is externally declared.

• It is also included in the array named vlog_startup_routines.

• The last entry in the array is zero.

};
