SystemC SCV - Icarus Verilog VPI sample

Co-simulation exsample of SystemC SCV and Icarus Verilog.

SystemC testbench provides constrained random stimulus to Verilog DUT, and captures responses from the Verilog DUT.

Prerequisites

• Centos7

• Icarus Verilog version 11.0

• SystemC version 2.3.3

• SCV version 2.0.1

Setup

Configure the SYSTEMC_DIR in bin/run_iv.sh to fit to your environment. The default is "/usr/local/systemc-2.3.3".

SYSTEMC_DIR=/usr/local/systemc-2.3.3

Running the simulation

git https://github.com/Kenji-Ishimaru/scv_iv_sample.git

cd scv-iv-sample/work
../bin/run_iv.sh ../scenario/test_1.v
