Chapter 3: Quick Start Example Design
R
To run a VHDL or Verilog functional simulation of the example design:
1. Open a command prompt or shell, then set the current directory to:
<project_dir>/<component_name>/simulation/functional/
2. Launch the simulation script:
ModelSim: vsim -do simulate_mti.do
IUS: ./simulate_ncsim.sh
The simulation script compiles the functional simulation model, the example design files,
the demonstration test bench, and adds relevant signals to a wave window. It then runs the
simulation to completion. After completion, you can inspect the simulation transcript and
waveform to observe the operation of the core.
Timing Simulation
Note:
Available only with a Full license.
This section contains instructions for running a timing simulation or the Ethernet
1000BASE-X PCS/PMA or SGMII core using either VHDL or Verilog. A timing simulation
model is generated when run through the Xilinx tools using the implementation script.
You must implement the core before attempting to run timing simulation.
To run a VHDL or Verilog timing simulation of the example design:
1. Run the implementation script (see “Implementing the Example Design” ).
2. Open a command prompt or shell, then set the current directory to:
<project_dir>/<component_name>/simulation/timing/
3. Launch the simulation script:
ModelSim: vsim -do simulate_mti.do
IUS: ./simulate_ncsim.sh
The simulator script compiles the gate-level model and the demonstration test bench, adds
relevant signals to a wave window, and then runs the simulation to completion. You can
then inspect the simulation transcript and waveform to observe the operation of the core.
