Getting Started with IDS-Validate

Prerequisites

To get started with IDS-Validate you need to put 3 things in place.

1. The RISC-V gcc tool chain
2. The RTL for the RISC-V
3. The UVM environment

1. RISC-V gcc tool chain

Setup procedure : riscv/riscv-gnu-toolchain: GNU toolchain for RISC-V, including GCC

Steps to install RISC-V Toolchain are updated in README.md of Git repository and step up in your server.

2. RTL for the RISC-V (Veer from Chips Alliance)

Link: https://github.com/chipsalliance/Cores-VeeR-EH1.git

Chips Alliance has published a register-transfer level (RTL) design abstraction of its in-house designed VeeR-EH1 RISC-V core and is available on GitHub.The design is licensed under the Apache 2.0 licence that allows the core to be used with or without modifications.

Set the ‘RV_ROOT’ environment variable to the root of the VeeR directory structure

Example for bash shell: `export RV_ROOT=/path/to/veer`

Example for csh or its derivatives: `setenv RV_ROOT /path/to/veer`

3. UVM home setup

• Go to:  https://www.accellera.org/images/downloads/standards/uvm/UVM-18002-2020-20tar.gz
• Download the uvm*.tar.gz file.
• Untar the file.
• Go to the extracted directory : cd uvm*uvmsrc
• Set the UVM_HOME path : setenv UVM_HOME `pwd`

(This is required to run the examples which are downloaded from this site)

• Go to UVM examples : cd ../examples/hello_world/uvm/

These are simple UVM examples designed to test the setup. They are already located in a zipped folder to test the setup.

• Co mpile the example using :

compilation_command -f compile_<toolname>.f

(example for questasim use : qverilog -f compile_questa.f)

• Run the example

4. Running Simulation

•  Irun (Cadence) setup.
  Setting up a UVM environment for Xcelium. Here’s a brief overview tailored for Xcelium:

• Install Xcelium:
  •  Ensure that Xcelium (Xcelium_Single_Core cdslmd 23.0) is installed on your machine

• Set Up Environment Variables:
  • Configure environment variables for Xcelium. Add the Xcelium bin directory to your PATH and set other required variables.
  • export PATH=$PATH:/path/to/xcelium/tools/bin

• Create Project Directory:
  • Establish a project directory where you will organise your UVM testbench and RTL code.
• Run the simulation

5. Command to Run firmware sequences on Validation Environment

Command line
Idsbatch <input file> -out “verilog arv_metal iss_firmware “ -dir <output dir> -bus apb

A directory “arv_metal” is created in the output directory with all the above files.

Run simulation :

• Change directory to the “arv_metal”
• Run one of the commands below as per the simulation environment:

           Xcelium:  make -f Makefile TEST_NAME=<test folder name> irun

Note:- The current support is for 32 RISC-V toolchain.
