# Simulator of RP2020 microcontroller Picosim is a system level simulator of RP2040 based boards. The simulator is based on SystemC framework. # Usage $ picosim RP2040 Simulator, Version 0.1 Usage: picosim [-L FILE] [-D] filename.elf Options: -L FILE Enable log output to the specified file -D Debug session -h Show the usage -V Show the version and finish # Build Build the SystemC library from sources for C++17 compiler: wget https://www.accellera.org/images/downloads/standards/systemc/systemc-2.3.3.tar.gz tar xzf systemc-2.3.3.tar.gz cd systemc-2.3.3 mkdir build cd build cmake .. -DCMAKE_CXX_STANDARD=17 -DDISABLE_COPYRIGHT_MESSAGE=ON -DCMAKE_INSTALL_PREFIX=/usr/local make make install The SystemC library is sensitive to the C++ standard. It must be compiled with option -std=c++17, to match the simulator. We cannot rely on a traditional install like 'apt install libsystemc-dev' or 'brew install systemc'. It would not link with the simulator. Configure and build the simulator $ cd picosim $ mkdir build $ cd build $ cmake .. $ make $ make install # Testing Run all tests: $ cd build $ make test Running tests... Start 1: tlm.smoke_test 1/91 Test #1: tlm.smoke_test ................... Passed 0.00 sec ... Start 89: c_extension.cswsp_test 89/91 Test #89: c_extension.cswsp_test ...........

Passed 0.00 sec 100% tests passed, 0 tests failed out of 91 Total Test time (real) = 0.40 sec Test run can be made faster by setting the variable `CTEST_PARALLEL_LEVEL` to the number of available processors on your workstation. For example: $ export CTEST_PARALLEL_LEVEL=16 You can also start the tests with `ctest` utility. See `ctest --help` for options. To run one specific test or a subset of tests, invoke `ctest` with `-R` option and a test name or a matching substring. Add -V to show the full output. # Links TODO
