Getting Started

• DirectC Interface — this interface allows you to directly embed

user-created C/C++ functions within your Verilog design

description. This results in a significant improvement in

ease-of-use and performance over existing PLI-based methods.

VCS atomically recognizes C/C++ function calls and integrates

them for simulation, thus eliminating the need to manually create

PLI files.

• Incremental Verilog Compilation — reduces the turnaround time

from design modification by minimizing the amount of

recompilation. This capability enables VCS to automatically

compare the current design against the previously compiled

database; it then recompiles only those portions of the design that

have changed. For details, see “Incremental Compilation” on page

3-3.

• 64-Bit Cross-Compilation and Full 64-Bit Compilation — VCS

offers a choice of methodologies for high-capacity compilation

and simulation. Its -comp64 option invokes a cross-compilation

process that compiles a design on a 64-bit machine, which can

then be simulated on a 32-bit machine. The -full64 option both

compiles and simulates a design on a 64-bit machine.

• Mixed Signal Simulation — Synopsys provides the Discovery

AMS: NanoSim-VCS User Guide and the Discovery AMS:

Enhanced NanoSim-VCS User Guide to NanoSim and VCS users

who need to do mixed signal simulation. See “Accessing the

Discovery AMS Documentation” on page 1-20.
