VITAL source code
The source code for VITAL packages is provided in the
/<install_dir>/
modeltech/vhdl_src/vital2.2b
, or
/vital95
directories.
VITAL packages
VITAL v3.0 accelerated packages are pre-compiled into the
ieee
library in the
installation directory.
Note:
By default, Model
Sim
is optimized for VITAL v3.0. You can, however, revert to VITAL v2.2b by
invoking
vsim
(p91) with the
-vital2.2b
option, and by mapping library
vital
to
<install_dir>/vital2.2b
.

Sim
VITAL compliance
A simulator is VITAL compliant if it implements the SDF mapping and if it
correctly simulates designs using the VITAL packages, as outlined in the VITAL
Model Development Specification. Model
Sim
VSIM is compliant with the IEEE
1076.4 VITAL ASIC Modeling Specification. In addition, Model
Sim
accelerates
the VITAL_Timing and VITAL_Primitives packages. The procedures in these
packages are optimized and built into the simulator kernel. By default, VSIM uses
the optimized procedures. The optimized procedures are functionally equivalent
to the IEEE 1076.4 VITAL ASIC Modeling Specification (VITAL v3.0).
