Performing HDL Functional Simulation
with Aldec Active-HDL
To perform HDL functional simulation with Aldec Active-HDL, first create a
script, “aldec_script.do,” and place it in the simulation directory. Copy the
following commands into the script:
cd “<path_to_toplevel_directory>/Platform/simulation”
workspace create sim_space
design create sim_design .
design open sim_design
cd “<path_to_toplevel_directory>/Platform/simulation”
set sim_working_folder .

# the VSIM command uses the Aldec for Lattice pre-compiled FPGA
# libraries. If the Aldec for Lattice simulator is not being
# used, it will be necessary to compile the behavioral code for
# the FPGA. For the ECP2, the behavioral code is located at:
# <isptools>/cae_library/simulation/verilog/ecp2
vsim testbench –L ovi_ecp2
Launch the Active-HDL software and execute the following command in the
console window:
cd <path_to_toplevel_directory>/Platform/simulation
# verify that you are in the correct directory
pwd

Performing HDL Functional Simulation
with Mentor Graphics ModelSim
To perform HDL functional simulation with ModelSim, first create a script,
“modelsim_script.do,” and place it in the simulation directory. Copy the
following commands into the script:
