🐌Yet Another Simulation Architecture
Author: Jude Zhang, E-mail: [email protected]
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.

Yet another simulation architecture® top scripts
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
-co, -componly Only compile without running tests
-b BUILD, -build BUILD
assign a specific build
-test_prefix TESTPREFIX
add testcase prefix
-r REPEAT, -repeat REPEAT
testcase will random run in given repeat round
-c, -clean Remove output build dir
-fail-fast Stop immediately on first failing test
-o OUTPUT_PATH, -output-path OUTPUT_PATH
Output path for compilation and simulation artifacts
-x [XUNIT_XML], -xunit-xml [XUNIT_XML]
Xunit test report .xml file
-xunit-xml-format {jenkins,bamboo}
Only valid with --xunit-xml argument. Defines where in
the XML file the simulator output is stored on a
failure. "jenkins" = Output stored in <system-out>,
"bamboo" = Output stored in <failure>.
-exit-0 Exit with code 0 even if a test failed. Still exits
with code 1 on fatal errors such as compilation
failure
-dont-catch-exceptions
Let exceptions bubble up all the way. Useful when
running with "python -m pdb".
-v, -verbose Print test output immediately and not only when
failure
-q, --quiet Do not print test output even in the case of failure
-no-color Do not color output
-log-level {info,error,warning,debug}
Log level of Yasa internal python logging. Used for
debugging
-p NUM_THREADS, -num-threads NUM_THREADS
Number of tests to run in parallel. Test output is not
continuously written in verbose mode with p > 1
-u, -unique_sim Do not re-use the same simulator process for running
different test cases (slower)
-version show program's version number and exit
-doc print doc file
-t TEST, -test TEST assign test name
-w [{vpd,fsdb,gui}], -wave [{vpd,fsdb,gui}]
dump waveform(vpd or fsdb), default fsdb
-cov [COV] collect code coverage, default all kinds
collect(line+cond+fsm+tgl+branch+assert
-seed SEED set testcase ntb random seed
-vh set verbosity to UVM_HIGH
-prof user defined option
-wave_name WAVE_NAME set fsdb waveform name
-pre_comp_option PRE_COMP_OPTION
previous compile option
-comp_option COMP_OPTION
compile option
-post_comp_option POST_COMP_OPTION
post compile option
-pre_sim_option PRE_SIM_OPTION
previous sim option
-sim_option SIM_OPTION
sim_option
-post_sim_option POST_SIM_OPTION
post sim option

Special thanks to Apollo Li for his IPsim 👍 give me read config file demo script
and Lars Asplund for his excellent job VUnit give me test_runner and report script
