4.1.3. Functional Simulation with Verilog HDL
Simulation scripts for the Synopsys* , Cadence, and Siemens EDA simulators are provided for you to run the design example.
Simulation scripts in the simulation folders for design example are located as follows:
- sim\ed_sim\mentor\msim_setup.tcl
- sim\ed_sim\synopsys\vcsmx\vcsmx_setup.sh
- sim\ed_sim\xcelium\xcelium_setup.sh
For more information about simulating Verilog HDL or VHDL designs using command lines, refer to the Questa - Intel FPGA Edition, ModelSim, and QuestaSim Simulator Support chapter in the Quartus® Prime Pro Edition User Guide, Third-party Simulation.
