Xilinx 3.2 manual Functional Simulation, Timing Simulation

Chapter 3: Quick Start Example Design

Functional Simulation

This section provides instructions for running a functional simulation of the CAN core using either VHDL or Verilog. Functional simulation models are provided when the core is generated. Implementing the core before simulating the functional models is not required.

To run a VHDL or Verilog functional simulation of the example design:

1.Set the current directory to:

<quickstart>/simulation/functional/

2.Launch the simulation script.

ModelSim: vsim -do simulate_mti.do

ncsim (ms-dos>):simulate_ncsim.bat

ncsim (Linux-shell%): ./simulate_ncsim.sh

The simulation script compiles the functional simulation models and demonstration test bench, adds relevant signals to the wave window, and runs the simulation. To observe the operation of the core, inspect the simulation transcript and the waveform.

Timing Simulation

Timing simulation is supported only for the Full-System Hardware Evaluation and Full license types, as the core cannot be implemented using a Simulation Only Evaluation license. This section contains instructions for running a timing simulation of the CAN core using either VHDL or Verilog. A timing simulation model is generated when the core is run through the Xilinx tools using the implement script. It is a requirement that the core is implemented before attempting to run timing simulation.

To run a VHDL or Verilog functional simulation of the example design:

1.Set the current directory to:

<quickstart>/simulation/timing/

2.Launch the simulation script:

ModelSim: vsim -do simulate_mti.do

ncsim (ms-dos>):simulate_ncsim.bat

ncsim (Linux-shell%): ./simulate_ncsim.sh

The simulation script compiles the timing simulation model and the demonstration test bench, adds relevant signals to the wave window, and runs the simulation. To observe the operation of the core, inspect the simulation transcript and the waveform.
