Simulating Your Design
In this example there is no DPI or PLI application and VCS does not
write a VCD or VPD file.
VCS used 1163834 bytes of memory, 56.66% of the total memory, to
simulate the design.
VCS used 890408 bytes of memory, 43.34% of the total memory, for
internal operations, such as scheduling, that can’t be attributed to any
part of the design. The designation KERNEL, is for these internal
operations.
The designation VCD is for the simulation time used by the callback
mechanisms inside VCS for writing either VCD or VPD files.
The Module View
The module view shows the amount of memory used, and the
percentage of memory used, by each module definition.

In this example the instances of module bigmem used 1048704 bytes
of memory, 51.05% of the total memory used. The instances of
module bigtime used 115030 bytes of memory, 5.6% of the total
memory used.
