3.3. VCS Simulation Setup Script Example
The scripts for VCS and VCS MX are vcs_setup.sh (for Verilog HDL or SystemVerilog) and vcsmx_setup.sh (combined Verilog HDL and SystemVerilog with VHDL). Read the generated .sh script to see the variables that are available for override when sourcing the script or redefining directly if you edit the script. To set up the simulation for a design, use the command-line to pass variable values to the shell script.
The Quartus® Prime software can generate two types of VCS simulation scripts:
- VCS MX flow scripts—support a 3-step flow where the source files compile into separate libraries (using vlogan and vhdlan commands), and the vcs command does not take source files as arguments.
- VCS flow scripts—support a 2-step flow where the source files are specified on the vcs command-line.
Using Command-line to Pass Simulation Variables
sh vcsmx_setup.sh\ USER_DEFINED_ELAB_OPTIONS=+rad\ USER_DEFINED_SIM_OPTIONS=+vcs+lic+wait
Example Top-Level Simulation Shell Script for VCS-MX
# Run generated script to compile libraries and IP simulation files # Skip elaboration and simulation of the IP variation sh ./ip_top_sim/synopsys/vcsmx/vcsmx_setup.sh SKIP_ELAB=1 SKIP_SIM=1 QSYS_SIMDIR="./ip_top_sim" #Compile top-level testbench that instantiates IP vlogan -sverilog ./top_testbench.sv #Elaborate and simulate the top-level design vcs –lca –t ps <elaboration control options> top_testbench simv <simulation control options>
Example Top-Level Simulation Shell Script for VCS
# Run script to compile libraries and IP simulation files sh ./ip_top_sim/synopsys/vcs/vcs_setup.sh TOP_LEVEL_NAME=”top_testbench”\ # Pass VCS elaboration options to compile files and elaborate top-level passed to the script as the TOP_LEVEL_NAME USER_DEFINED_ELAB_OPTIONS="top_testbench.sv"\ # Pass in simulation options and run the simulation for specified amount of time. USER_DEFINED_SIM_OPTIONS=”<simulation control options>
