YASA

🐌Yet Another Simulation Architecture

Author: Jude Zhang, E-mail: zhajio.1988@gmail.com

YASA is an open source simulation framework for SystemVerilog/UVM testbentch released under the terms of Apache License, v. 2.0. It support mutli_simulators, multi_languages, lsf etc. It support several excellent features. Such as: customized command line arguments, can add any compilation options or simulation options, can running a testcase with random seeds for several rounds or running a group of testcases, each testcase has several command line options.

Dependencies:

python 3.6
configobj
argparse
vcs or incisive simulator

Typical Usage:

show help doc

%> python3 yasaTop.py -h

positional arguments:
  {lsf}

optional arguments:
  -h, --help            show this help message and exit
  -g GROUP, -group GROUP
                        assign test group name
  -show {test,group,build}
                        show test list, group list or build list
  -so, -simonly         Only run simulation without compile step

  -test_prefix TESTPREFIX
                        add testcase prefix
  -r REPEAT, -repeat REPEAT
                        testcase will random run in given repeat round
  -c, -clean            Remove output build dir
