New Horizons

Welcome to my blog

My name is Sven Andersson and I
work as a consultant in embedded
system design, implemented in ASIC
and FPGA.
In my spare time I write this blog
and I hope it will inspire others to
learn more about this fantastic field.
I live in Stockholm Sweden and have
my own company

FPGA design from scratch. Part 5
I have decided to use the Cadence Incisive HDL simulator for my functional verification. I will setup my own simulation environment using a tool called Mongoose. Mongoose is a graphical user interface (GUI) program, designed  for setting up and running a simulation testbench. It can be used as an interactive tool or used for running regression testing in batch mode.
I started to develop the Mongoose program more than 10 years ago and have been using it in all my ASIC verification work. It can be setup to utilize any Verilog or VHDL simulator and it can also integrate
Specman for automatic generation of functional tests. In this chapter I will describe how to setup and use the Cadence Insisive HDL simulator in the Mongoose Simulation Environment. Read more about Mongoose in the Zoo Design Platform presentation.

Setting up the simulation environment

Before starting Mongoose we have create a working directory. The working directory is the directory from where we start all our simulations:
mkdir /home/svenand/root/projects/ETC/verification
We don't want to remember this long file name so we will define an environment variable instead:
/home/svenand/root/projects/ETC/verification (csh and tcsh)
Add this statement to your .cshrc file
ETC_VERIFICATION=/home/svenand/root/projects/ETC/verification (sh and bash)
Add this statement  to your .bashrc file
Go to the working directory: cd $ETC_VERIFICATION
and start the Mongoose program: mongoose &

Open the terminal window by clicking the button.

Next thing to do is to create the file structure needed to support all activities during the simulation phase. Select Create Environment from the Setup menu and fill in the information:
  • Design name : ETC
  • Environment Variable Name : ETC_VERIFICATION
  • Working Directory : $ETC_VERIFICATION
  • Language : Verilog
  • Simulator : NC-SIM (Incisive HDL Simulator)
  • Simulation Setup : Functional
  • Script File : $ETC_VERIFICATION/CreateEnvironment

Click the Setup Script button to generate and run the environment setup script. When finished click the Mongoose Setup button to save the whole Mongoose setup in the file .mongoose-setup stored in the working directory. The next time you start Mongoose the setup file will be read and your are back to where you were the last time.

Too see what the file structure looks like open the File Tree Browser and click the Set Root button to display the first level of files. Double-click on a directory to see the next level of files.

This table explains the usage of the different directories. This is only a recommendation, you can change almost everything if you like to.

 Directory  Description
 bookmark Stores the directory bookmark file
 command Stores saved commands
 database Stores the compiled simulation libraries
 debug Stores debug commands for interactive debugging
 design Stores the verilog or VHDL design files
 designDefine Stores design definition files (behaviour, RTL, netlist)
 help Stores help information
 input Stores TCL input files to the simulator
 key Stores the key file from the simulation
Stores macro library definition files
Stores log files
Stores the macro library files
Stores all the script files generated from Mongoose
Stores Simvision waveform viewer plot files
Stores different result files from the simulation
Stores auxilary script files
Stores sdf setup files
Stores Mongoose setup files
Stores simulator setup files (cds.lib, hdl.var)
Stores Verilog task files
Stores Verilog testbench file
Stores Verilog testcase files

To display the current directories setup open Setup->Environment.
